Precautions
Operating voltage: Before powering the subwoofer make sure the operating voltage of
the local power supply is identical to that specified for the subwoofer.
AV amplifier: Ensure that your AV amplifier is switched off before connecting the
subwoofer. Make sure you have connected the plus (+) and minus (-) binding posts
of each speaker to the corresponding plus (+) and minus (-) terminals on the amplifier
or receiver.
Connection with AV amplifier: Turn off the subwoofer before connecting the input signal
cable to its internal amplifier.
Binding Posts: Make sure all binding posts are tight, especially if using bare speaker
wires. Contact between + and - wire strands may cause a short-circuit and potentially
damage your equipment.

2.2 Product features
Bipolar BPS and BPT Speaker Systems are designed to be used with TX-8SUB / TX-
10SUB or our THX Select Certified Subwoofers. BPS and BPT Systems, due to their slim
cabinets, should use your receiver’s “Small Speaker” setting with a crossover point of
150Hz or more for best performance. This is also dependent on your room’s dimensions,
the subwoofer placement in the room, as well as your listening taste.
BPS satellites are especially designed so that they can either be placed horizontally or
vertically, surrounding you with a high-quality, wide-dispersion surround sound.
Crystal Acoustics BPS and BPT speakers are available as 2.0 pairs of satellites or towers
or 5.1 system sets with TX-8SUB / TX-10SUB subwoofer, as following:
1. Bipolar satellites BPS 2.0 (pair of satellite speakers)
•• Bipolar Satellites BPS with 2 x 3” woofers and 1 x 1” tweeter for use as front or surround
speakers.
6
2. LCR speaker (pc)
• LCR speaker for use as a center, front or surround speaker on any system
3. Bipolar Towers BPΤ-3Τ 2.0 (pair of tower speakers)
•• Bipolar Tower Speakers BPT with 2 x 3” woofers and 1 x 1” tweeter for use as front
or surround speakers.
4. Bipolar System 5.0 BPT
•• 4 Bipolar Tower Speakers BPT with 2 x 3” woofers and 1 x 1” tweeter for use as
front or surround speakers
•• 1 LCR center
5. Bipolar System 5.1 BPS & TX-8SUB / TX-10SUB
•• 5 Bipolar speakers BPS for use as the centre, front and surround speakers
•• 1 subwoofer TX-8SUB / TX-10SUB
The overall presentation is engagingly vivid with your TX-8SUB / TX-10SUB subwoofer
supporting flat anechoic response from 40Hz to 200Hz. It also features accurate room
response from 29Hz to 300Hz. With these specifications, your new speakers reproduce
sound beautifully and deliver powerful action films with the authority of larger and more
expensive speakers.
Your new speakers feature:
• Electronic protection for tweeters and woofers
• Magnetic shielding
• Wide horizontal dispersion that permits full, flat frequency response throughout a room
• Controlled vertical dispersion diminishes ceiling and floor reflections for superior
focus and imaging.
• High sensitivity for low power amplifiers and A/V receivers
• TX-8SUB / TX-10SUB 8-inch or 10inch long-throw woofer
• TX-8SUB / TX-10SUB flat frequency response from 30Hz or 40Hz to 200Hz
• TX-8SUB / TX-10SUB line level (RCA) input (AUDIO IN)
• TX-8SUB / TX-10SUB variable volume control
•• TX-8SUB / TX-10SUB selectable phase control (0
ο
or 180
ο
)
•• TX-8SUB / TX-10SUB signal sensing auto turn ON/OFF

3 Positioning your new Bipolar speakers
The sound field reproduced by a multi-channel audio system envelops listeners to create a
very three-dimensional image. To achieve the best results follow these set-up procedures.
> Ideally, all five speakers should be equidistant from the listener and develop identical
sound levels when fed identical signals.
> BPT floor standing placement: Due to the woofers at the rear of the cabinet, avoid
placing the BPT-3T floor-standing speakers close to the wall, but at a distance. This
way the BPT speakers will surround you with a wide range response for a truly lifelike
sound.
> BPS placement: The BPS speakers can be placed horizontally or vertically and either
on a shelf or on a wall with their metal wall brackets. Due to their unique bipolar 45
0
design they can be placed as close to the wall as you like without dispersion problems.
Depending on the placement you prefer and the distance from your listening position
you may experiment with the exact on-axis position of the BPS speaker by shifting the
speaker left and right in regards to the centre. Choose the position you like most.
> It may not be practical for your speakers to be set equidistantly in your room, but
electronic time delay circuits easily compensate for this and can be found in any
processor or receiver’s set-up menu.
> We recommend positioning your TX-SUB close to the listening position (Figure 1).
*** Additionally, using the Crystal Acoustics Wireless Transmitter-Receiver you can easily
connect your subwoofer with the minimum of fuss and free from the clutter of speaker wires.
> Avoid positioning the subwoofer equidistantly from room boundaries like walls.
> Avoid positioning it near corners where walls are not of solid construction.
> Corner placement may exacerbate room resonance, resulting in boomy, muddy bass.
> Further experiment with speaker positioning; place the subwoofer near your listening
position and play jazz with acoustic bass and move around the room.
> Place the subwoofer where you hear the deepest, best controlled and most articulate
bass frequencies.

Figure 1: Speaker and subwoofer placement
> Your TX-8SUB / TX-10SUB subwoofer is magnetically shielded to reduce the amount
of stray magnetic energy emitted from the speaker’s motor structure. This greatly
increases flexibility when placing the unit close to video monitors, as there is very little
stray magnetism. Certain types of TV are particularly sensitive to stray magnetic fields.
If your TV produces distorted colours after installing your subwoofer, simply increase
the distance between your TV and the subwoofer, until normal colour and operation is
returned.
CAUTION! This subwoofer has electronics built into the cabinet. Do not place the
cabinet next to sources of heat or near sources of excessive moisture.

Figure 1: Speaker and subwoofer placement
3.1 Placing BPS, LCR or BPT speakers as front left and right
Try to follow these set-up suggestions as illustrated in Figure 1. Use our online
Room Acoustics Designer® (www.crystal-acoustics.com) to find other placement
suggestions.
1. Place your BPS or BPT speakers equidistantly from your TV/projector’s screen
2. Measure the distance between your left and right speakers
3. Measure the distance between the listening position and the midpoint between your
left and right speakers
4. The difference in length between them should be no greater than 15%
5. Angle your speakers inwards towards the listening position and find the optimum
angle for best sound
6. Adjust your speakers so that the tweeters are about ear-height at the listening position
if possible
7. Move the speakers towards room boundaries (walls or corners) to reinforce low
frequencies. Do the opposite to reduce lower frequencies
8. Do not place the speakers too far apart or a hole develops in the centre image
9. Do not place the speakers too close together or the soundstage collapses into a fuzzy
mono centre -only image.
3.2 Placing BPS or LCR as a centre channel speaker
> TV screen: Place your your BPS or LCR speaker directly above or below the screen
depending on which is closer to ear level.
> Projector screen: Place your BPS or LCR speaker behind or in front of the centre of
the screen whether it is acoustically transparent or not.
3.3 Placing BPS, LCR or BPT speakers as left and right surrounds
Due to their bipolar design both BPS and BPT speakers are optimized to deliver an
attractive, engaging, powerful and enveloping sound field. Follow the setup suggestions
as illustrated in figure 1.
1. Place the speakers slightly behind the primary listening position
2. Adjust the speakers to fire towards each other behind the seating area
*** Additionally, using the Crystal Acoustics Wireless amplifiers TR-100 or TR-60 (optional) you
can easily connect your surround speakers with the minimum of fuss and free from the clutter
of speaker wires.
The LCR speaker includes an invisible wall mounting system at the rear of the cabinet for
either vertical or horizontal placement.
1. Due to their unique bipolar 45
ο
design they can be placed as close to the wall as you
like without dispersion problems.
2. Depending on the placement you prefer and the distance from your listening position
you may experiment with the exact on-axis position of the BPS speaker by shifting the
speaker left and right (when placed horizontally) or up and down (when placed vertically),
in regards to the centre. Choose the position you like most at the listening position.
Wall bracket Installation
1) Screw the Bracket top (4) on the back of the speaker.
2) Place the bracket bottom (8) on the wall. Make sure to use the appropriate screws so
that the bracket is fully and stably placed.
3) Position the speaker Bracket top (4) on the Bracket bottom (8) until they are fully
seated and use the Molded nut (1) to tight them together adjusting the speaker position
on the same time. Make sure the Metal nut (9) is fully tightened in order to hold the BPS
speaker weight.
