Quick Install Steps

The purpose of this section is to provide a fast
and easy overview of installation and setup for

your BG loudspeakers. However, your

speakers are high performance devices which
will benet from taking time and attention dur­ing set-up. Reading the entire manual will also
greatly assist in achieving the best possible per­formance.

If you encounter any problems or difculties in
installation, please refer to the Installation portion

of this manual.

If any questionss are, please contact your autho­rized BG dealer, as they will provide you with the
appropriate technical and eld support.

Step 1 : Unpacking and Assembly

Open the package and remove your new BG
speaker form it’s packing materials.

Screw in spiked feet or stick on rubber feet and

position them as needed. Adjust them so that the

speaker is stable and rests on all four feet.

Step 2: Placement

Place your Z-Series loudspeaker in the desired
location. (Please refer to our setup guide on

pages 5-10.)

Step 3: Signal Connection

Using the speaker cabling of your choice, con­nect the terminals on the rear panel of your
speakers.

Pay attention to connect the speaker’s red termi-

nal post to the ampliers positive (+) post and the
speaker’s black terminal to the amplier’s nega­tive (-) post. Tighten down the terminals onto the

connectors or wire.

Step 5: Congure and Calibrate

In multi-channel systems and when using a sub-

woofer, set the crossover, distance and level of

each speaker. (Please refer to our setup guide

on pages 5-10.)

Step 6: Enjoy!

General Infomation

Important Ownership information

Read and Follow Instructions – Please read

this entire manual thoroughly before unpacking
and setting up your BG Z-Series loudspeakers.

For maximum performance and years of trouble­free enjoyment, all operating and use instructions

should be followed.

Retain – DO NOT discard any factory packing
material. The packing and shipping materials may
be required in the unlikely event your loudspeak­ers need to be moved or shipped to another loca­tion or be serviced.

Cleaning – Use a wax-free cleaning substance
only (i.e. Pledge™) with a soft, dry polishing cloth

not a paper-based chamois. DO NOT apply any
cleaning solutions to the grill cloth.

General Considerations

Break-In Times: Typically a BG loudspeaker

requires not less than 48 hours of operation at

moderate sound level before reaching its opti-

mum sound quality. This improvement may be

rather subtle but noticeable for a trained listener.

Note: Do not play your loudspeakers excessively

loud to try to accelerate this process!

Amplier: BG loudspeakers are extremely ac­curate and deliver a high degree of detail and
resolution. Therefore a good 100-150 watt per

channel amplier or receiver will deliver adequate

power for a typical system and room size. Your
authorized BG dealer can recommend an ampli-

er best suited to your needs.

Liquid – DO NOT place BG loudspeakers near

an open source of liquid that may spill on the

loudspeaker surfaces.

Heat – DO NOT place BG loudspeakers near a
direct heat source.

Tipping – Place your loudspeakers on a smooth

at surface and with the Z-7 tower, use the en­closed spiked feet on carpeted surfaces. A loud-

speaker tipping over can pose a hazard for small
children and pets.

Stereo Music and Home Theater

Optimum Setup

Refer to the diagram on page 7 that depicts a
recommended layout for BG loudspeakers. This
diagram is an overhead view of a typical listening
room with the video screen located at the top of

the diagram (the front of the room). Keep in mind

that the room is a part of the sound reproduction

system and has a signicant effect on the sound
you experience. This is especially true for lower
frequencies (see subwoofer setup on page 9).

Locating your loudspeaker close to the wall
increases bass output. It may also increase the

boominess of the bass and articially alter the

loudspeaker’s tonal balance. We recommend

that you adjust the position of the loudspeakers,

moving them in and out gradually (from the front

and side walls), to get the sound you prefer. You

may toe them in or out (rotate them around their

vertical axis towards or away from your listening
position) to improve high frequency balance (as
indicated by the dashed lines on the diagram). In
general, best results are obtained when the front
left and right loudspeakers have their axis inter-

secting behind the position of the listener.

The relative location of your listening position
to the loudspeakers is important as well. If pos-

sible, do not select a listening position less than
three feet (one meter) from the rear wall of the
room. As with adjusting the placement of your
loudspeakers, you can also adjust your listening

position to get the most desirable bass reproduc-

tion and high frequency resolution.

If you place BG loudspeakers on a shelf or in
a wall unit make sure the loudspeakers are not
recessed too deeply and nothing is in front of or

in close proximity to the drivers to obstruct the

sound.

Installation

Multi-Channel Music and Home Theater

If you plan to use your BG loudspeakers for home
theater or multi-channel audio, here are some ad­ditional recommendations:

1. The center channel loudspeaker should be
positioned directly above or below your television.

NOTE: The Z1, Z5 and Z7 models are mag-
netically shielded and can be used in very close

proximity to tube (CRT) television. When using
the Z62 and Z92 with a CRT TV, do not place the
speakers closer than 2 feet (0.6 m) to it, to avoid

interference.

2. If you are using a projector, you will need a

suitable stand to position the center channel loud-

speaker on the oor below the screen or a brack­et above or below the screen. Aim the loudspeak-

er so it is directed at your listening position. The
center channel loudspeaker should be as close
as possible to the screen so the voice soundtrack
appears to come from the video image.

If you place BG loudspeakers on a shelf or in a

wall unit, make sure the loudspeakers are not

recessed too deeply and nothing is in front of or

in close proximity to the drivers to obstruct the

sound.

Processor Setting – We recommend using the
small loudspeaker mode on your processor to

protect your loudspeaker’s low frequency driv­ers from extremely low bass signals. This setting

will also allow higher dynamic range and cleaner
sound at louder levels.

This manual addresses 5.1 surround sound
systems. Where 7.1 or higher systems are being
utilized, see your authorized BG dealer for ad­vanced setup procedures.

The optimum position for all ve loudspeakers

should be the same distance from the listening

position (distance A, B and D are equal), see dia­gram on opposite page. If it is not possible, the

delay and level adjustment functions available in
most home theater processors can compensate
for the differences in distances. The diagram
shows the optimum placement for the rear loud­speakers. The subwoofer should be placed be­side or behind either the left or right front speak­er. For multiple subwoofers see your authorized
BG dealer for advanced setup procedures.

Subwoofer Setup

Optimal Setup for Your BG Z-Sub

The Z-Sub Active Subwoofer by BG Corp is the

perfect complement to the entire Z-Series line
of loudspeakers. The Z-Sub is a compact yet

powerful, active subwoofer designed to partner
perfectly with our loudspeakers for use in stereo,

high performance home theater or multi-channel
audio. Or you may choose our Z-Sub for use with

any high quality loudspeaker system.

The Z-Sub consists of one 10” long excursion
composite cone woofer, augmented with a 10”
down-ring passive radiator, 150 watt RMS class
AB power amplier and detachable power cord.
Features include input signal sensing Auto/On,
phase switch, line-level input, speaker-level input/
output, variable crossover and variable volume

control.

Connections

1. L&R line-level input jacks. These inputs are
designed for low-level RCA component connec­tions and interconnects derived directly from your
receiver or processor. If your receiver or proces-

sor only has one subwoofer output, plug it into

the Right or Left low-level input.

2. L&R speaker-level / high-level ve-way bind­ing posts are provided as well. These inputs and
outputs are designed for high-level subwoofer
connections and pass-through loudspeaker inter­connections. Five-way binding posts are provided

to accept up to 14 AWG speaker cable.

3. Detachable power cord. This subwoofer is
supplied with a detachable power cord for ease
of installation and transportation.

Subwoofer Placement, Connection and
Adjustment:

Placement – The Z-Sub should be placed beside
or behind either the left or right front speaker (see

diagram). When using more than one subwoofer

consult with your authorized BG dealer for ad­vanced setup procedures.

Care should be taken when handling the Z-Sub
as it contains a bass driver (a.k.a. passive radia-

tor) on the bottom that could be damaged with

mishandling. The feet included with the Z-Sub
help protect the passive radiator and provide the

required 1” (2.54 cm) clearance from the oor to

the passive radiator.

Subwoofer Setup

Adjustments

4. On/Off power switch. Once the Z-Sub is po­sitioned in the room and the proper cables are

installed, the On/Off switch should be engaged in

the on position for initial power up. The LED turn­ing red indicates the unit is powered on.

5. Auto/On switch. In the Auto position, the ampli­er is in stand-by mode and turns on automati­cally when the signal arrives from the amplier

or receiver. It turns off after 10 minutes when

a signal is not present. In the On position, the
amplier is always on regardless of the presence
of a signal. The Auto position is recommended for

normal operation.

6. Phase switch. This switch is specically de­signed to eliminate phase discrepancies between
the Z-Sub as well as the primary LCR loudspeak­er’s phase. The phase relationship depends
on the relative distance between the sub and
loudspeakers. If your sub is located within 5 feet

(1.5m) from either loudspeaker or between them,

try the switch in the 0-degree position. If your

sub is located further away than recommended,
experiment with both switch positions and choose
the position where you experience fuller base.

7. Low frequency cut-off control. This allows
adjustment of the cut-off frequency (within 50­150Hz) of the subwoofer’s low pass crossover.
When using the sub for two-channel stereo, the

knob should be adjusted to match the primary

loudspeaker’ low frequency roll-off to create a

seamless integration between them. For home

theater, set the subwoofer at 150Hz while setting

your processor/receiver to crossover the system

at 80Hz or 100Hz.

8. Volume control. This control adjusts the loud-

ness level of the subwoofer and matches it with

the loudness level of the loudspeakers. Adjust

the level to achieve a balanced sound between

the subwoofer and the loudspeakers. Your room,

source material and your preferences will deter­mine this.

BG Planar Ribbon Technology

Concept

BG’s Radia Planar Ribbon technology consists

of an extremely thin, low mass, high-temperature
polymer diaphragm as a carrier for at aluminum

conductors made via a special etching process.
This is suspended within a symmetrical mag-

netic eld created by a double sided (push-pull)
Neodymium magnet structure. As the alternat­ing electrical current of the musical signal ows
though the conductors, the diaphragm moves in

and out producing sound.

Key Benets

- Low Mass, High Temp Diaphragm - for high

power handling. outstanding transient response

and damping,

- Push-Pull Symmetrical Magnet Structure – pro-

duces symmetric magnetic eld for high sensitiv­ity and extremely low distortion.

- High strength Neodymium Magnets – are 20
times stronger than ceramic magnets resulting in

higher sensitivity, higher output and reduced size

and weight.

- Patented PDR technology and patent pending

NEO10 technology allow wider high frequency
dispersion while maintaining extended bandwidth

and new levels of output without audible distor­tion.

- Resistive Impedance - non-reactive load is
amplier friendly. Very low self inductance mini­mizes intermodulation and phase distortion for
increased accuracy and coherency.
