THANK YOU FOR CHOOSING BLAUPUNKT!

KEY FEATURES

– 2 –

Congratulations! You are the now the owner of an exceptional loudspeaker from the audio enthusiasts at Blaupunkt. Our engineering staff has spent considerable time refining our ProComponent subwoofers in order to introduce great sound to the consumer at an affordable price. Now entering our third generation of the PC family of product, we still feature the rugged design and flexible installation. But now, we have evolved the speaker design with a new polypropelyne cone material and more aggressive cosmetics.

Not only do we offer you a great product but also a supportive owners manual. This manual can be used as a teaching guide due to its brief, but informative, explanations of loudspeaker and enclosure design and references to other reading and computer materials available today. We are also are very concerned about the end consumer using proper installation techniques for the highest performance possible from their new loudspeakers. MOST important are the concerns with safety and the installation process. Since our Blaupunkt retail dealers have the tools and experience for an optimized and safe installation, we always recommend they do the final vehicle integration. But, should you choose to install these products yourself, please take the time to read this manual completely and abide by all precautions.

It has been repeatedly proven that remarkably high audio system performance can be achieved by moderately priced components. 90% of all consumers really don’t need $500 woofers with 120 oz magnets for their listening habits. The PCwg subwoofers are designed for HIGH POWER HANDLING LEVELS, HIGH SOUND PRESSURE LEVELS, and

FLEXIBLE INSTALLATION CHOICES.

The focus on our new subwoofers is the vacuum formed polypropylene cone material offering lighter mass compared to older paper cones but without the flexing properties common to paper. This gives a much “tighter” bass response without distortions often found at high listening levels. Below is a good summary comparing old cones with the new technologies.

In addition to the vacuum formed poly cones is the expansion of our extended pole program. The extended pole piece of the subwoofer is lengthened by a few millimeters but the performance results are significant. The non-linear fields around the voice coil’s gap are greatly reduced thus improved heat dissipation (higher power handling) and increased cone movement control (higher power but with “cleaner” response).

Vacuum Formed Poly Cones

V ACUUM FORMED POLY

New “VFP” Vacuum Formed Polypropylene Cones

•Lightweight, and mechanically rigid, poly cones play louder with

less power

•Acoustically inert, poly cones do not “color” the sound of the music

•Environmentally resilient poly maintains shape & thickness,

ensuring premium tonal quality for years

Conventional Inexpensive Paper/Plastic Cones

•Non-uniform cone thicknesses (are heavy & often generate

internal “bending” motions)

•Self-resonant materials & construction (standing waves occur

yielding strong tonal shifts)

•Paper & cheap plastic cones warp & change mass over time

due to swings in temperature & humidity (degrading performance)

Speaker Cone

New “EXP” Extended Pole Design

• Increased cone travel for higher “clean” sound pressure

levels

• More symmetrical magnetic operating field for lower distortion

• Better heat dissipation offering higher power handling

capability

Conventional Magnetic Pole Design

• Limited linear cone travel (high level distortion at lower

volume levels)

• Uneven magnetic field distribution throughout cone travel

(common distortions)

• Average heat dissipation (therefore only average power handling)

Before disassembling your beautiful new car you need some basic installation knowledge and skill with common hand and power tools. Following such basic installation tips and warnings will prevent possible damage to the vehicle and also prevent possible fires.

■

AGAIN...READ THE MANUAL! There is a lot of helpful information in this manual that will save time and prevent problems later.

■

COVER THE VEHICLE WORK AREAS - Use fender covers or blankets to protect the work areas from scratches or dings.

■

DISCONNECT THE (-) LEAD ON THE BATTERY - No sparks or fires please!

■

“REVIEW” THE INSTALLATION - Before using any tools or moving vehicle components, take five minutes to review the installation intentions (e.g., verify that an enclosure will fit in an area of a car before tearing out all the interior).

■

“REVIEW” THE VEHICLE - Before drilling any holes or cutting into any surfaces, make sure there are no fuel or hydraulic lines behind the surfaces. Also make sure there are no wires routed directly behind or near the desired mounting area (remember...screws can often extend 1-2 inches behind the mounting surface).

■

ENSURE PROPER FIT - Before cutting or drilling, make sure the speaker will physically fit in its desired location. Check for clearance around rear deck torsion bars or other structural elements.

■

EVERY CAR IS ASSEMBLED DIFFERENT - Every auto manufacturer uses different assembly techniques. Take care in removing/modifying all trim panels and mounting surfaces since they often use unique screws or snap fasteners that are difficult to replace if they are lost or broken.

■

BE CAREFUL WITH CABLE ROUTING - When routing audio cables, make sure RCA and speaker wires are routed away from high current power lines for audio amplifiers and vehicle systems lines when possible. This will help prevent noises from creeping into the audio system, plus prevent potential damage to the vehicle wiring itself.

■

BE CARFUL WITH ALL CONNECTIONS - When making connections, make sure each connection is clean and properly secured. Observe all polarity markings carefully to ensure proper end performance.

■

CAUTION - FUEL TANKS AND FUEL LINES ARE NOW LOCATED DIRECTLY BENEATH THE REAR DECK IN MANY CARS - CHECK FOR ADEQUATE CLEARANCE BEFORE EVEN CONSIDERING SUCH A MOUNTING LOCATION!

SAFETY CONCERNS

INSTALLATION WARNINGS!

– 3 –

We always recommend you have your Blaupunkt speakers professionally installed but the installation process is often so easy that the average consumer can achieve success with little trouble. Regardless of the person installing, you should be sure to review the following points before proceeding with the installation:

■

READ THE MANUAL! Understanding the product and installation limitations before lifting a screwdriver.

■

WEAR SAFETY GLASSES AT ALL TIMES - Flying debris are always dangerous.

■

PROTECT THE VEHICLE - Always disconnect the negative battery cable before starting any kind of installation work. This prevents a possible high current electrical short (potential fires).

■

HEAT - Keep all speakers away from nearby hot components such as amplifiers or vehicle components that heat up over time such as hoses, high current wires, and braking system components.

■

GIVE YOURSELF LOTS OF TIME - Rushing to complete an installation nearly always ends up with problems.

■

DO NOT LISTEN AT HIGH SOUND LEVELS FOR A PROLONGED TIME - If connected to high power amplifiers, these speakers have the potential to cause permanent hearing loss after listening at maximum volume levels for several hours.

SYSTEM DESIGN GUIDELINES

– 4 –

SYSTEM PLANNING The largest possible impact on any audio system (home or car) is the tonal quality of the loudspeakers, their respective placement, and their overall efficiency (loudness). A 4x20 watt amplifier and four dual-cone speakers is never going to make an impressive performance. The first major improvement comes with the addition of a strong low frequency performance which give the emotional sensation of “strength” to the audio system. Often many newer cars have acceptable coaxial speakers in acceptable mounting locations. By adding a subwoofer speaker and amplifier, the system, although only moderate performance, becomes surprisingly pleasant for most listeners. To move to the next step up in performance you must install some good component speakers for the mids and highs (“satellite” speakers) then add a separate subwoofer speaker for the lows.

SYSTEM IMPLEMENTATION Speaker configurations are a common problem in autosound installations. We want to achieve a sound field in front of us (like a live concert) as compared to sound partly from the front and partly behind us. This dictates good midrange and tweeter speakers in front, usually mounted in the doors for good left/right balance, with high-pass crossovers set greater than 80-100 Hz. The best stereo image will occur when the front speakers are spaced as far forward as possible attempting to achieve nearly equal distance from the speakers to the listening position. For deep bass a subwoofer is required but is nearly always located behind us in a rear trunk or rear hatch area. If the subwoofer crossover is too high in frequency male voices can be heard “gurgling” out of the subwoofer speaker and therefore pulls the sound-stage to the rear of the car, which is very unnatural and therefore undesirable.

MULTI-CHANNEL SYSTEMS Moving up to amplifiers around 4x50 watts on the satellite channels with component speakers is a common and acoustically rewarding step. The improvements in acoustical left/right balance and stereo imaging are quickly obvious. By adding a dedicated subwoofer amplifier the perceived “strength” of the system is often dramatic.

In order to achieve such a multi-channel system a dividing network must be installed that keeps the low frequencies out of the midrange speakers. Such a “crossover” network directs the higher and lower frequencies to their respective drivers. Such a crossover can be “passive” (simple coils and capacitors) that limit the operating frequencies seen by their respective speakers. A crossover can also be “active” where an electronic box must be installed in front of a dedicated amplifier and process the signal via small signal RCA cables before its amplification. In general, active crossovers are most common for the low/mid transition area because they best filter the low frequencies and are physically small compared to the passive equivalent. Passive crossovers are most often used where they provide adequate filtering in the mid/high frequency transition with satellite midranges and their tweeters. Passive crossovers at these higher frequencies require only small coils and capacitors so they are easy to install and perform well.

AMPLIFIER POWER Amplifier choice and power is important but less so compared to speaker choice and placement. Matching the rms (continuous) power capability to that of the speaker is important but it should be noted that “under-powering” a system can often damage more tweeters than providing slightly more power than stated by the speakers. If the speakers are rated to 50 watts rms, you can often run 60-80 watt rms amplifiers without concern IF

the amps are not driven into clipping (deep distortion). IMPEDANCE is the electrical resistance to AC current flow and is typically 4 ohms for most car speakers. Impedance loads should not fall below the manufacturer’s recommended minimum impedance or the amp will heat up and sometimes shut down (2 ohms/channel is common).

SOUND QUALITY VS. LOUDNESS All well designed sound system can provide good sound quality and still play loud. Above about 120 dB (decibels) the sound isn’t perceived as getting much louder due to the non-linearities of the human ear. A four loudspeaker system with the perspeaker efficiency rating of 90 dB (1 watt/1 meter) will often achieve about 110-115 dB if driven by 100 watts per speaker channel. (Although often debated, this is more than enough sound pressure level for most humans to enjoy and can easily

cause hearing loss if listened to at such levels for hours at a time.)

SUBWOOFER ENCLOSURE TYPES

In the car audio world there are 5 types of subwoofer enclosures commonly used; Infinite Baffle, Sealed Box, Vented Box, Single-Vented Band-Pass, and Dual-Vented Band-Pass. No single design is superior because each has its own compromises in performance, power handling, and design/construction complexity. You need to make the choice based upon personal listening habits and requirements.

Having “Multi-Box” design characteristics, your Blaupunkt subwoofer performs remarkably well in ALL installations, but is optimized for Sealed, Vented, and Single-Vented Band-Pass configurations due to its moderate Qts values. Below is a summary of these 5 popular enclosures. More importantly their respective advantages and disadvantages are noted so an intelligent choice can be made regarding the best box for you.

INFINITE BAFFLE (a.k.a. “Free-air”) is simply a woofer installed in the back shelf of the car that uses the trunk as the enclosure. Advantages: simple installation and adequate performance; Disadvantages: only moderate sound pressure levels and poor power handling.

SEALED BOX (a.k.a. “Closed Box”) offers one of the best compromise in performance and power handling. Advantages: simple box construction, high power handling, excellent transient response, and smooth low frequency roll-off. Disadvantages: moderate to large box sizes, moderate efficiency, moderate sound pressure levels.

VENTED BOX (a.k.a. “Ported Box” and “Bass Reflex”) is simply a sealed box but with a specifically tuned tube inserted. It extends the low frequency response compared to a sealed box. Advantages: low cut-off frequency, low distortion in its operating pass-band, excellent efficiency, good transient response, moderate power handling (in its pass-band), and small box sizes. Disadvantages: complex design and limited power handling if driven hard at very low frequencies (below port tuning frequency).

SINGLE-VENTED BAND-PASS (a.k.a. “4th Order Band-Pass”) is one of the best designs for the car. It is basically a “compromise” between a sealed and vented box in performance and reliability. Advantages: small box volumes, extended low frequency performance, and can be used with VERY high power amplifiers. Disadvantages: slight drops in efficiency compared to a vented box and increased box design and construction complexity.

DUAL-VENTED BAND-PASS (a.k.a. “6th Order Band-Pass) is unfortunately often used in the car as an acoustical “fog-horn” - lots of high-SPL but marginal tonal quality if the enclosure isn’t precisely constructed. Advantages: tr

emendous SPL’s from VERY small boxes Disadvantages: VERY complex construction and susceptibility to cone overexcursions for frequencies outside its operating region if a high quality electrical filter is not used.

At some point, the subwoofer speaker must be electrically connected to an audio amplifier, be it a dedicated bass-only amp or the amplifier built inside the radio. Clearly, the highest performance level will be from the outboard dedicated amp due to its typically higher power (e.g., 100 watt amp vs. 20 watts from the radio). To avoid disappointing performance we recommend power amps with rms power levels exceeding 50 watts if possible. This is NOT a minimum value; it is simply a nice power point where you begin to really FEEL the substantial improvements in sound offered by a good subwoofer/amplifier system.

Now that we have concluded that an outboard dedicated subwoofer amplifier is needed for optimum performance we must somehow process the signal in order to limit the audio signals to only low frequencies. This must be done via a “crossover” which can be “active” or “passive”. As stated earlier in this manual, the active system is preferred due to its small size and better frequency contouring. But it must be placed in front of the amplifier and process the signals via the RCA cables. This is rarely a problem in most installations.

The passive design is more of a “brute force” process requiring large inductors and capacitors but it is often a “cheap and dirty” way to get bass response into the car quickly and without noise problems sometimes associated with active crossovers. Its bigger advantage is when you wish to operate in a combination stereo high-pass/bridged subwoofer mode common with 2 channel amps. Such configurations are shown in the manuals of most amplifiers. Below is a simple summary showing how to connect such a passive installation.

For most installations, simple hand tools are adequate if replacing the factory speakers. If the factory locations, or other convenient mounting locations are not used, you will need power tools for drilling and cutting plastics and metal. A good starting list is summarized below:

■

Tape measure and ruler

■

Marking pen and starting punch

■

Phillips and flat blade screwdrivers (small and medium sizes)

■

Nylon wire bundle ties

■

Pliers: standard vice-grip and needle nose styles

■

Light-duty trim pry-bar for removing door trim

■

Cutting shears or nibbling tool for cutting thin and medium gauger metal

■

Wire cutters, wire strippers, electrical tape, crimping pliers and appropriate crimp-on terminals

■

Power drill with appropriate sized drill bits (1/8", 3/16", and 1/4" to start)

■

Electric jig-saw (sabre saw)

We strongly recommend that you have your Blaupunkt subwoofers professionally installed. If you choose to do your own installation please note the following important information:

■

Before cutting any trim or metal make sure your final installation will clear all moving parts, factory cables, wires, and hoses.

■

Be sure to leave enough slack in the wiring to prevent the need to pull or street wires if service is needed later.

■

Tie down all loose wires with nylon wire ties to prevent them from getting caught in moving parts or shorted out due to abrasions from moving over time.

■

Never mount speakers in a vehicle’s wheel wells or areas where they may be subjected to moisture or road spray.

■

Proper speaker polarity must be observed. The polarity positive side is marked by a (+) symbol or a red colored dot. At low frequencies woofers out of phase will acoustically cancel one another thus resulting in little bass output.

■

Although components used in Blaupunkt speakers exceed most production quality standards, speaker frames can still be twisted by improper installation on uneven surfaces.

■

This can occur when surfaces are heavily padded or carpeted and the screws are unevenly tightened or over tightened. The results will be a damaged voice coil assembly due to knocking it off center.

■

When installing more than one speaker per amplifier channel be sure that the combined impedance values will not damage the amplifier should they be too low (i.e., a common minimum impedance value of 2 ohms is common).

■

Speaker wire size should be sufficient to carry the full power of the amplifier (16 gauge or larger is sufficient in about 90% of all audio systems assuming <100 watt amplifiers and wire runs under 20 feet)

■

Speaker wires should be electrically and physically isolated from the vehicle and routed away from any factory wiring that carries high currents or noises (e.g., ABS brake systems and engine computer signals)

FINAL SYSTEM TEST & TROUBLESHOOTING

Once the system is installed, turn on the total audio system main power switch and SLOWLY turn the volume up using a music selection with a full range of frequencies. If you experience any of the following problems take corrective action immediately to prevent damage to the speaker, amplifier, and vehicle.

AREA AND VOLUME CALCULATIONS

Although many enclosures can now be purchased in prefabricated form, building your own enclosure is often fun, acoustically rewarding, or even a necessity to properly fit many vehicles. In order to build such a box there MUST be a basic understanding of mathematic principals or you will wind up wasting incredible amounts of time and money by making mistakes in the box design and assembly.

BASIC MATHEMATICS FOR ENCLOSURE CONSTRUCTION

– 9 –

The areas of surfaces or openings are calculated in square inches (in2). Such calculations depend upon height and width values or diameters for circles

AREAS

circle or a hole rectangular wall or area triangle wall or area

AREA CALCULATIONS

Circle or hole Area = 0.79 x d x d Rectangular wall or area Area = h x w Triangle wall or area Area = 0.5 x h x w

The volumes of assemble shapes are measured in cubic inches (in3). Such calculations depend upon height, width, and depth calculations for rectangular shapes and a diameter and height for a tube shape.

AREA AND VOLUME CONVERSIONS

Technical data for speakers are often given in English and Metric unit values (e.g., inches and meters). Also, when calculating dimensions we must often flip between size formats (e.g., cubic inches and cubic feet). To easily convert back and forth between two formats you can use the conversion table below.

Before final design, wood cutting, and assembly of the enclosure some basic box construction issues need to be understood. These items are acoustically related, some are construction tips, and some are simply to ensure a long lasting product for the listener.

■

Infinite baffles are simply a piece of wood holding up the woofer to the back deck of a car. If you chose this installation (which is generally a poor performer) you must take great care in sealing/caulking all holes that vent into the back seat for proper bass response.

■

Wedge shaped boxes are simply a triangular box added to a rectangular box.

■

Mathematically add up the volumes of these two boxes and you have the total of a wedge shaped box.

■

When making the calculations, be sure to adjust interior box volumes for port volumes and woofer displacement volumes.

■

All calculations should be made in advanced of cutting wood out. If the final box is off by +/- 5% of optimum values don’t worry about it; you will rarely be able to hear the difference! This is very important since prefabricated boxes often work well even if off a little bit. Also, if you do forget to compensate for woofer and port tube volume displacement, it is rarely acoustically noticed by most people.

■

Very low frequencies simply do not care about the shape of the box. Such wavelengths allow for nearly any reasonable shape or length but really odd shapes should be avoided so they can be easily cut and glued.

■

Particle board, MDF, or high grade birch plywood are good materials to build boxes with thicknesses of 5/8"-1" (1425mm). Solid wood panels should actually be avoided of splitting and warping over time in the car environment.

■

All seams in the box should be glued, screwed, then caulked to prevent panel separation and air leaks over time.

■

Cross bracing of panels is important for large boxes to prevent the panels them selves from radiating sound.

■

Acoustical damping material (e.g., fiberglass batting material 2-4" thick) should cover about 50% of the interior walls. This helps reduce high frequency resonances and increase the box volume as seen by the woofer by about 10-15%.

■

Spraying the interior walls of the box with a damping material such as tar based automotive undercoating is one of the best things to help dampen wall resonances.

■

The final box should allow for servicing the woofer at a later time should it be damaged for any reason.

■

5-way binding posts mounted on the box for electrical connections are highly recommended. It is then easy to remove

the box from the vehicle for service or theft protection.

■

Where possible, use the largest diameter port tubes to prevent wind noise. PVC plumbing pipe is inexpensive and is common in 3, 4, and 5" diameters. PVC “elbow” connectors allow you to make turns inside the box with the average diameter being along the centerline of the tube.

■

Try to always use active (electronic) crossovers. Today, most power amps have them built in. The mounting distance from the side of the woofer and the port should be less than 12" or so if possible. Regarding simple vented boxes, you CANNOT achieve lower frequency response by simply lowering the port tuning frequency from its recommended value. This severely over-damps the box and results in a very “muddy” sound for the box.

Before gluing and screwing everything together, lightly “tack nail” the sides together and make sure the box fits in the vehicle. Also, look carefully to see if the woofer magnet has enough depth of clearance from the back wall. There are many other things to think about when design and building subwoofer boxes but they are too numerous to mention here. But, for those interested, please refer to some of the related reading for more information on speakers and audio in general.

This page is offered ONLY as a “starting point” for box construction. Although our woofers work well in a wide range of box volumes, many people try to build boxes too large assuming they will get better bass response with such monstrous sized boxes. This is NOT acoustically correct and you need to pay attention to the recommended volumes and predicted performance data when making your box decision. On the other hand, the more common mistake is to jam a big woofer in an extremely small box and have virtually no low frequency response due to the “choking” effect of an undersized box.

To help understand how large a “cubic foot” really is we have provided the drawings and tables below with some common relationships for height, width, and depth. These are not “magical” sizes or relationships in any way, just popular sizes that will fit in most vehicles and perform well.

All dimensions are stated for exterior sizes and are calculated with compensations for box wall thickness using 3/4" wood. Also, each volume is adjusted for air volume displacements for a woofer (average 0.15 cu ft for 10/12" woofer) and a mid size port (3" dia. x 7" long). Please be aware of the small impact that box size fluctuations has on the end sound quality: loudspeaker enclosure interior size deviations of +/- 5% from ideal are rarely heard. In addition, interior objects such as port volume displacements and cross braces can usually be forgotten about in all but the smallest of boxes.
