IMPORTANT NOTICE

All new speakers require a minimum of 60 hours break-in-time before they begin to
sound the way they are supposed to. A speaker's performance improves significantly once
broken in. It is critical that you have at least 60 hours on your speakers before you evaluate
them. Don't worry if your speakers do not sound perfect the first time you play them. This is
normal until they are broken in. If you are having difficulty getting enough hours on your
speakers and your 30 day return privilege is getting near, call us. We will work with you.
Please give us the courtesy of breaking the speakers in before you determine they don't
sound right.

Many of our customers break their speakers in by:

3

A) Leaving them on at moderate listening levels when they are not home.
B) Leaving them on at moderate listening levels while they sleep.
C) Running pink noise through them.

These methods are not convenient for everyone and we understand this. But please
know that you are not giving yourself, your speakers or us a fair chance if you do not break
them in before critical evaluation.

THANK YOU!

The Titan XL Powered Subwoofer

Thank you for your order and congratulations on becoming the owner of an ACI speaker system. The
Titan XL powered subwoofer(s) will provide you with many years of listening pleasure!

The Titan XL was designed to please music lovers who don’t want to fashion their habitats around
large, obtrusive boxes. Attractive and reasonably sized, the Titan XL takes up little space and there are many
options for room placement including “hidden” placements. The attractive cabinets are excellent as a small
end table or plant stand. Hookup to any music system is easy! The Titan XL is a fantastic addition to your
video system as well. The Titan XL will allow you to “feel” the impact and power of The Matrix, War of the
Worlds, Lord of the Rings, Chronicles of Narnia, etc. We know you will enjoy many years of satisfaction with
your Titan XL(s)!

The Titan XL has plenty of powe r to move a lot of air. The downfiring driver reproduces all low organ
pedals, symphonic bass drums, tympani, video special effects and synthesizers with stunning realism. Equally
important, the Titan XL does a fine job with the subtle but musically critical qualities of difficult instruments
such as piano and string bass.

The enclosure is constructed of ¾” non-resonant high-density fiberboard with extensive internal
bracing. The standard finish is a classy black satin. Optional finishes include an inlaid cherry veneer or piano
gloss black finish. The specially developed ACI 12” driver has extremely long excursion and a balanced cone­motor system supported by a heavy cast-frame that operates with very low distortion. A specially developed
rubber surround precisely terminates the stiffened fiber cone.

4

Many subwoofers add unacceptable colorations and actually degrade the performance of otherwise
fine speakers. The Titan XL is adaptable for use with virtually any satellite, electrostatic or ribbon speaker. If
you are satisfied with your present speakers but just want more bass power and extension, the Titan XL(s)
may be the perfect answer. If you own speakers from manufacturers such as B&W, KEF, Apogee, Quad,
Thiel, Magnaplaner, Martin Logan, Wilson, etc., you’ll find your listening pleasure greatly enhanced with the
Titan XL subwoofers.

Titan XL Subwoofer Setup

Integrating a sub is a process that requires following ordered steps. You’ll find it easy in some
rooms/systems, and very time consuming in others. The key is to eliminate each variable one at a time. It
really helps to have a test CD with sinewave or warble tones. That’s why we include just such a disc, free with
purchase of our subs. Use of the setup CD is optional. Please refer to the attached directions for the test CD.

The electronics of the Titan XL performs the following functions:

Input Level: This controls the volume of the Titan

XL when using the Right and or Left inputs. The
volume needs to be set at the same volume as
your main speakers to get a seamless blend. When
using the Theater input, the volume on the
subwoofer is bypassed and will be controlled by
your processor/receiver.

Lowpass Filters A & B: Each filter has a 12db/oct
roll off and is used to set the upper cutoff point of
the subwoofer. Normally, you will set both filters at
the same frequency for a 24db/oct roll off. In some
systems it may be advantageous to be able to
independently adjust these filters for the optimum
blend.

Phase Control: The phase is variable from 0-180
degrees. Correct phase is dependent on
positioning of the sub relative to the main and the
listening position. The correct phase setting will
yield the greatest level of bass.

5

Left & Right Line Level Inputs: Use either or both
of these inputs. You will need to set the Input Level
and Lowpass Filters A & B.

Theater Input: Connect to this input from your sub
output on your receiver, preamp or processor. Set
Lowpass Filters A & B to 250Hz. Input Level is
bypassed and volume is controlled from your
system's subwoofer volume control.

Left & Right High-Pass Outputs: Works with the line level inputs, they cut the frequency of your main
speakers off at 100Hz with a 12db roll off. Rarely used we suggest using the optional passive high-pass filters
instead.

LED Light: It is red for a few seconds as the amp warms up. The light will turn green when the amp is ready,
even if there is no signal going to the amp.

On/Off Switch: Used to turn the amp on and off. Normally the amp is left on all the time. When not playing, it
draws about the same about of power as a nightlight.

Power Cord: The cord is non-detachable and can be plugged into any standard two-prong outlet.

Miscellaneous:

• A limiter and current sensing feedback circuitry protect the driver from being overdriven and reduce
distortion.

• The discreet outputs of the amplifier deliver over 250 watts RMS to the woofer with extremely low
distortion.

• A temperature switch monitors the output devices. In the event of excess heat the switch will shut
down the circuitry to prevent damage. Once the heat sinks cool the power will be restored. Because
the electronics have been designed and "tuned" to the woofer and cabinet, the Titan XL offers
incredible performance in relatively small cabinet.

Speakers Level Adapter

Y-Adapter
RCA Female-Female Adapter

Two of these are supplied with each Titan XL subwoofer. The Speaker Level

Adapter converts an amplified, (speaker level), signal to the line level signal required by the subwoofer. Not
required for line-level hookup. The adapters may be installed directly in parallel with your main speakers.
This can be done at the speaker outputs on your receiver or amplifier. Alternately you may put these in
parallel with your speaker at your speakers input terminals. You may attach any type of speaker cables to
the speaker cable end using either electricians twist nuts or a twisted, soldered and wrapped connection. If

running shielded interconnects to sub, you will need to purchase RCA Female - Female adapters.

Used to split a line level output into dual outputs. Use with shielded RCA interconnects. For

example; use Y-Adapters at pre-amp outputs to get dual outputs. One set of outputs goes to the subwoofer(s),
one set of outputs goes to the main amplifier inputs.

Used to join two shielded RCA interconnects. May also be used to join the ACI Speaker Level Adapter to any
RCA shielded interconnect.

Step One: Initial Placement

Determine initial placement of the sub. This is often a matter of "where it will fit" in the room. You will also need
to plug the Titan XL into a 120-volt wall receptacle. The Titan XL is supplied with a power cord. If this is not
long enough, you may use an extension cord of at least 16 gauge. Three of the best places to put your Titan
XL:

1. Place the sub in one of the corners behind the main speakers. A corner placement behind the main
speakers usually yields the deepest, cleanest bass. As long as the subwoofer is correctly adjusted it
will not be boomy or overbearing. The sub doesn’t have to be placed “tightly” in the corner, just as
near as possible.

2. Place the sub near the wall, behind the main speakers. Approximately 1/3 of the width of the room is
often ideal.

3. Place the sub along one of the sidewalls. Approximately 1/3 of the length of the room is often ideal.

If you have the flexibility to try different placements, we’d encourage you to do so. Every room is different.
Experimentation is the best way to find the best placement. One trick is to place your subwoofer in your normal
listening position. Listen or take measurements from your subwoofer placement options to find the ideal
position. For example, if your two options are the left front corner and somewhere along the right sidewall,
you’ll listen and or take measurements at these two positions.

(See also placement diagrams later in the manual.)

Step Two: Hookup and Adjustment

The Titan XL subwoofer may be integrated into virtually any quality audio or audio-video system. First you
must determine your hookup scheme. Select from the choices below and then make adjustments.

There are essentially two types of hookup and adjustment:

1. Home Theater ( 5.1 - 7.1 systems ) Systems with a subwoofer output on your receiver or processor

OR

2. Stereo (two-channel) Systems without subwoofer output

The following diagrams and descriptions illustrate various hookup options . *Please note, for the sake of

clarity only one channel is show.

Home Theater - Hookup

This approach requires a shielded RCA cable from the subwoofer output on your receiver or processor to one
of the inputs on your Titan XL.

• Choose either the Left or Right input for the highest sound quality and the greatest bass extension.

• With the Left or Right input you can adjust volume at the sub and at your receiver or processor.

• Choose the Theater input only in the unlikely situation that you are able to drive your Titan XL into

shutdown mode. This can occasionally occur with certain content played at high levels for extended
periods of time, or if the Titan XL is placed such that the rear mounted amplifier is not able to cool
adequately. The Theater input adds additional filtering that rolls off the low end response of the sub to
allow higher sound pressure levels.

• The Theater input bypasses the subwoofer volume control so level will be controlled at your receiver
or processor.

If you wish to use multiple subs simply split the signal with a Y-adapter and run separate interconnects to each
sub. Check your receiver or processor documentation for instructions in how to turn on the subwoofer output
as well as how to adjust the level.

Home Theater - Adjustments

Adjusting the Titan XL for Home Theater

1. Set the crossover frequency dials A & B initially to 250Hz. For best sound quality, experiment with
adjusting these controls to the crossover frequency of your receiver or processor, usually 80 or 100Hz.

2. Adjust phase to give the highest output level. (Please refer to the test CD procedures for this)

3. Input level is bypassed when using the theater input and your processor controls the volume. If using
the Left or Right input you can adjust volume at the sub and at your receiver or processor.

Stereo (Two-Channel) - Hookup

First you must determine your hookup scheme. Your choice of hookup will be determined by the capabilities of
the rest of your system. The Titan XL has RCA, line-level inputs and Speaker Level Converters are also
provided for speaker level connection. (Additional hookup options may be found on our website at

www.audioc.com.) Select from the following and then make adjustments:

A) Systems that do NOT have preamp outputs:

1. Hookup with Speaker Cable using Speaker Level Converters

This is sometimes referred to as "bass augmentation". The main speakers are run full-range and the
subwoofer is used to augment or fill in just the lower bass. Connect a second set of speaker cables in
parallel with your existing speaker cables. This set of cables is run to our speaker level converters, which
plug into the subwoofer left and right inputs. (If using stereo subs you will run one cable to each sub). Set
filters A & B, the input level, and phase controls to get a seamless blend with your main speakers.
As an option, you can add a capacitor(s) in series with your main speakers. The capacitor will block some
of the lows that might otherwise overdrive your main speakers. This is a very imprecise method and
generally only used with small speakers with limited low frequency power handling. We recommend trying
approximately 200mfd of capacitance. Polypropylene capacitors are suitable though expensive.
Alternately, non-polarized electrolytic (NPE) capacitor(s) with a minimum 100 volt rating may be used.

8

2. Hookup with Shielded Interconnect using Speaker Level Converters

Connect speaker level converters in parallel with your main speakers. Connect a female to female RCA
adapter to the speaker level converter and use shielded RCA interconnect cables to connect to the
subwoofer. (If using stereo subs you will run one interconnect to each sub). (DH Labs Subsonic Cable is
perfect for this application) Same capacitor option as #1

B) Systems that DO have preamp outputs:

1. Processor with Preamp outputs & Main amp inputs

Use Y-Adapters to split the signals from the left and right preamp outputs. Connect one end of each Y-Adapter
to left or right main amp input, (using a short RCA interconnect). Use proper lengths of shielded interconnects
to connect the other ends of the Y-Adapters to the right & left inputs on the sub. (If using stereo subs you will
run one interconnect to each sub). Your main speakers will receive a full range signal. To reduce low
frequency content to your main amp and speakers, use optional High Pass Filters plugged into the main amp
inputs.

9

2. Separate Preamp & Amp

Shown with Y-Adapters. If your preamp has two sets of outputs you will not need the Y-Adapters. Use
proper lengths of shielded interconnects to connect one set of outputs to your main amplifier and one set
of outputs to your sub left and right inputs. (If using stereo subs you will run one interconnect to each sub).
Your main speakers will receive a full range signal. To reduce low frequency content to your main amp
and speakers, use optional High Pass Filters plugged into the main amp inputs.

Stereo (Two-Channel) - Adjustment

Adjusting the Titan XL for Stereo:

1. Set Initial Adjustments: Crossover frequency dials: 80Hz, Phase: 0, Input Level: ½ way

2. Set Phase: Adjust volume level so sub is audible with an 80Hz test tone from the included test CD.
Adjust phase for maximum output at the listening position. This is most easily accomplished with an
extra person to work the switch / control. If using an SPL meter such as the Radio Shack, it might be
easier to track the change with the 80Hz Warble tone rather than the 80Hz Sinewave.

3. Set Input Level: Start with input level all the way down and set both crossover frequency filters to
35Hz. As you play music with a repetitious bass line, adjust the input level upward until it is just
consistently audible. The low bass should fill in naturally. You are looking for bass that goes deeper,
not necessarily louder.

4. Set Crossover Frequency: With the frequency filters at 35Hz, gradually adjust upward until the bass
seems full, without any missing notes , and then back off just a bit. At first, move both filters up an
equal amount. Adjust up or down until the subwoofer best matches the cutoff of your main speakers. It
may help to adjust crossover B higher in frequency than crossover A. The most natural results will be
with the lowest crossover point that doesn’t leave a “gap” in the response. Lower crossovers will allow
the subwoofer to audibly “disappear” and placement is less critical.

5. Fine-tune: Sit back and listen with a variety of music. Make any changes one at a time to fully assess
the effect. Take your time!

Troubleshooting Setup and additional considerations

• If you try to use the sub to adjust for recordings that lack bass you'll go nuts, adjust the sub to well
recorded music and leave it alone. You'll never get it perfect for all music because the music isn't
recorded consistently!

• If the music seems to lack warmth, try adjusting the frequency control up just a bit at a time. Too
much, and the sub becomes easily audible by itself.

• If your main speakers have ports (vents) try stuffing them; this sometimes improves the transition
drastically. The ports can easily be stuffed with cloth. Just stuff it so that you no longer get air pressure
coming from the vent when the speaker is playing. Stuffing the port changes the response from fourth
order to second order and yields a more gradual rolloff in the main speakers. It can make all the
difference in the world!

• If you have a problem with hum there are generally three possible causes:

1. Ground loops or power issues are the most common cause of subwoofer hum. Turn everything

off and remove all connections from the Titan XL to the rest of the system. Turn the Titan XL back
on. If the hum is gone, the problem was probably caused by a ground loop. In this case, you will
need to either use a "cheater" plug on the Titan XL power cord, or use a GLE (Ground Loop
Eliminator), available from Radio Shack. If the hum is still there, plug the Titan XL into an outlet
on a different house circuit. If the hum is gone, it might be a matter of the subwoofer picking up
interference from something in the house electrical system such as fan speed control or light
dimmer. Use a different outlet. If the hum remains, continue to step #2.

2. Poor connections or RCA interconnects can cause hum. If you move the shielded cable that

connects the Titan XL to your system and you hear a change in the hum it is likely you have poor
shielding or a defective RCA plug. Replace the cable.

3. Amplifier damage is the least likely cause of hum. However, if you have ruled out ground loops,

power issues, or a defective connecting cable, it is possible that there is a problem with the
amplifier. Contact ACI service for assistance.

determine which is best for you.

Other System Considerations

If the rest of your system does not work properly or is not correctly connected you will not get the best
performance from your system.

To eliminate problems we recommend the following:

• Use the finest associated components you can afford. Turntable, cartridges, pre-amps, amplifiers,
(receivers) and cables all have profound impact on the sound of your system. Accurate speakers let more
detail through. You will hear more of the beauty of the music, but flaws in your system and/or source
material may be more obvious. Any good audio system is made up of matched components. You wouldn’t
use bargain recap tires on a new Ferrari, and you shouldn’t use inferior components with a high quality
speaker. Your ACI Titan XL(s) performs like subwoofers costing far more. Keep this in mind when
selecting the rest of your system.

• Know your source material. People often blame their audio gear for poor recordings. A great number of
popular recordings are of inferior sound quality. Unfortunately this applies to records, tapes, DVDs and
CDs. There are more good quality recordings available now than just a few years ago, but poor
recordings with rolled off low bass, harsh and constricted mids and highs and little stereo monitor speakers
that are grossly inaccurate. Consider that some producers still mix recordings to sound best on cheap
table and car radios! This doesn’t mean you can’t enjoy these recordings, but you should try a few of the
best audiophile recordings just to see how terrific your system can be when fed a good signal.

14

Should you have more than one Titan XL?

A single Titan XL provides a major and cost-effective improvement for most people in most rooms with most
music. However, there are a number of reasons to consider more than one Titan XL.

-Stereo subwoofers: This is more important if the main speakers used need a rather high crossover

frequency. Some very careful listeners may want stereo subwoofers with a crossover as low as 85Hz while
many others might be more than happy with a single subwoofer crossed over above 120Hz. Many of the

popular 3 piece satellite subwoofer systems in the $500-$1000 range have crossovers above 160Hz! Some
listeners can hear the problems immediately while many people never notice the problem.

-Increase output levels and lower distortion: Some people with large rooms and/or a need for higher than

average output levels will want to use more than one Titan XL. For large spaces and/or very high volume
requirements any number of Titan XLs can be added to a system. The Titan XL adds bass power and
extension, it takes nothing away from the main system.

-Get smoother in-room response than with a single subwoofer: In some situations, loading the bass into

the room from two or more points can give a better balanced bass throughout the room.

-A third Titan XL may be used for the rear surround channels: The Dolbytm standard calls for a bass roll-

off in the rear channels…but Dolby Digital recordings have full-range bass content in the rear channels. Some
film lovers feel that having a subwoofer for the rear channel improves impact and realism with such films.

Avoiding Damage

Audio Concepts, Inc. speaker systems are designed for the purpose of accurate reproduction of music
in the home. We do our best to make our speakers rugged and reliable. We invested effort in the Titan XL to
make it as indestructible as possible. We’re happy to say that after producing and selling the Titan Series for
years we’ve yet to have one blown driver returned! Of course there’s always Murphy’s law! Under certain
abusive conditions it may be possible to overdrive the Titan XL. This is possible with your receiver or pre-amp
volume control way up with excessively high distorted signal levels.

MORE IMPORTANTLY, as reliable as the Titan XL has been designed, you still need to be careful not
to over-drive and damage your main speakers. So please read over the following causes of speaker failure.
Remember, just because you added the power and bass response of the Titan XL, your main speakers won’t
handle any more power than before.

You can protect your system by following a couple of very simple guidelines:
A) If it sounds at all distorted, turn it down. Distortion is a warning sign that should not be ignored.

B) Don’t use tone controls or equalizers if possible. IF you must use them, monitor the system carefully.
C) Beware the party damage epidemic. Speakers are more often damaged during parties. All those bodies
soak up sound, requiring more output to sound as loud, bass and treble controls are sometimes cranked up
and nobody is listening for distortion.

In over twenty-nine years of daily evaluation of all types of speakers on everything from ten to one
thousand watts with all kinds of music, we have never damaged a driver without hearing audible distortion. If it
sounds bad, turn it down, and you will never damage a speaker.

Speaker Break-in ****Important!!!

Allow at least 60 to 70 hours of playing time before your new ACI Titan XL(s) will sound the best. The
adhesives and materials used in manufacturing must stretch and flex properly before a speaker will sound its
best. After break-in the bass will be tighter and go lower.

15

For quicker break-in:

-Play the Titan XL(s) at medium-high volume while away from home. Use music with a lot of low bass
content. A CD player on repeat works fine.

Troubleshooting

Occasionally we get a call from someone who feels there is a problem with their ACI speaker. At least
a couple of times a year we will get a call or letter that goes something like this: “Speaker not working properly,
can’t get enough sound even with the volume turned way up.” The problem may be different, but with this little
information to go on it is almost impossible to trouble shoot the problem “long distance”.

The following checklist may help:

1) Are all system hookups properly connected, no partial shorted wires, or reversed connections, etc?

2) Did you try the rest of your system with other speakers to determine if the problem exists with the

speakers?

3) Please be realistic in your expectations. Our speakers offer excellent value, but we can’t beat the laws of

physics. For instance, a medium sized speaker such as the Sapphire XL sounds excellent but will not play
as loudly as a very large speaker.

IF for any reason you aren’t satisfied with the sound you’re getting from your speakers we want to
know about it. Make sure the speakers have had adequate break-in time. Before you call or write, please
try to narrow down the problem and eliminate other factors. We will need to know:

◊ The size of your room

◊ Where you have the speakers placed

◊ What other equipment is in your system

◊ Have you tried other speakers (which ones, and did they eliminate the problem)

◊ Any other specific symptoms or information you can provide
