Boston Acoustics Classic Series Wireless-ReadySubwoofers

Thank you for choosing Boston Acoustics. The Classic Series Wireless-Readysubwoofers incorporatehigh-qualitycomponents that produce the legendary Boston Sound. The subwoofers are ideally suited for use in ahigh-quality5.1 channel home theater or stereo music system. They are capable of impressive deep bass and high output from remarkably compact enclosures. In addition, they feature BassTrac®, a proprietaryBoston-designedcircuit that tracks the input signal to the subwoofer and prevents its amplifier from being driven into audible distortion. The benefit: the bass stays clean and strong at any listening level.

Unpacking the System

Carefully unpack the subwoofer. If there is any sign of damage from transit, report it immediately to your dealer and/or delivery service. Keep the shipping carton and packing materials for future use. Be sure to keep your purchase receipt in a safe place, as it may be required for warranty purposes.

CPS 12Wi, CPS 10Wi, and CPS 8Wi subwoofers

Placement Options

Place the subwoofer next to a wall or in a corner near your main speakers. The sound is typically best when the subwoofer is within 15 feet (4.5m) of the main speakers. The sharp 24dB/octave crossover roll-offpermits placement farther from the main speakers if necessary. Since the ear is unable to localize the low frequencies of the subwoofer, the bass still appears to come from the main speakers. Experimentation is key, however most positions in the room will work well.

The level of bass output from the subwoofer will vary at different positions in a room. When placed near walls, its loudness is emphasized. Corner placement provides the most bass output. Placement completely away from walls may produce too little bass. Regardless of the natural bass level within the room you will always have the ability to adjust the level of the subwoofer from the built in volume control. If at any time you move the subwoofer be sure to check all of your settings.

IMPORTANT: Do not place the subwoofer where there is a chance of contact between the rear panel and drapes or furniture.

Position subwoofer

in corner for maximum bass output



After your speakers are properly placed, you are ready to wire your system.

NOTE: Power is always supplied to the subwoofer electronics unless it is unplugged or switched to theMute position using theAudio On switch located on the rear panel. Theauto-oncircuitry only activates or deactivates the power amplifier. Make sure your subwoofer and receiver are unplugged when making the connection (230v models include a main power switch which turns off all power of the subwoofer).

Power: When plugging your subwoofer in be sure to use a wall outlet, or dedicated electrical outlet. Some receivers will provide a switched outlet. Do not use this. Theseon-boardelectrical outlets do not offer the amount of current or proper isolation required by a power amplifier, such as the one in your subwoofer.

Line level or LFE: On most systems use theline level input or theLFE input. These inputs accept theline-levelsignal from your receiver’s subwoofer output. Your receiver’s manual should indicate which input is most appropriate.

Connecting the Subwoofer to Digital Home Theater Systems Using LFE

Digital 5.1, 6.1 and 7.1 home theater electronics dedicate one channel (the “.1”) to reproduce the special low-frequencyeffects (LFE) information (such as explosions and thunder) contained indigitally-encodedsoundtracks.

Select ”subwoofer-yes”from your receiver’sset-upmenu. Hooked up this way, the receiver’s amplifier is relieved of having

to reproduce the difficult low bass signals that can drive the receiver into audible distortion. In some cases it can also depend on several other settings within a receiver. We recommend consulting your receiver manual for further assistance in this area.

Use an RCA cable (not included), as shown, to connect your digital receiver’s LFE/subwoofer output to the subwoofer.

Connect the other end to the Line Level/LFE input.

Connecting the Subwoofer to Stereo or Dolby® Pro Logic®

For stereo or Dolby Pro Logic systems use the “sub out” connection from your receiver to the input on the subwoofer marked

“L” or “R”.

Connecting to Electronics Without a Subwoofer Output

If the receiver in your system does not have a subwoofer or LFE output you can connect the CPS Wi subwoofer to a preamp output. Use a stereo RCA cable (not included) to connect the preamp outputs to the “L” and“R” Line Level inputs.

CPS 12Wi

Adjusting the Crossover Control

When using the Line Level inputs (not theLFE input) the subwoofer’sbuilt-incrossover is engaged. As a starting point, set the crossover control on the subwoofer about 10Hz higher than the lower limit of your main speakers’ bass response.Fine-tunethe crossover setting by ear for the smoothest blend with your main speakers. The best setting of the crossover control will depend on speaker placement and personal preference.

Speaker level

Use these high-levelterminals with receivers that do not have subwoofer output. The speaker inputs accept both left and right channel speaker signals from your receiver. When using a home theater receiver, set the speaker type to “Large.”The large setting will produce a fuller sound.

CPS 12Wi



Certain receivers use speaker grounding circuits that may be incompatible with external powered audio products, such as powered subwoofers. When speaker wire is used instead of line level cables, this incompatibility can result in an audible hum when the receiver is turned off or switched to a different speaker channel.

If this should happen with your Boston Acoustics subwoofer, you will need to make a ground cable and connect it to either RCA line input on the subwoofer and any unused

RCA line input or output on your receiver

(see diagram). The proper ground cable for this application should consist of two male




RCA plugs that have their negative outside






terminals (or “sleeve”) connected to each





other by any length of single conductor



copper cable. The inside positive (or “pin”)

Optional WT 50 Wireless Transmitter

Transmitter Power

Plug the transmitter power supply into a power outlet. The transmitter power supply requires very little power so you can plug it into an auxiliary power outlet on the receiver. Plug the connector on the power supply cable into the transmitter power input labeled 18V DC.

Wireless ID Switches

Both the CPS Wi Subwoofer and optional WT 50 Wireless Transmitter have Wireless ID switches (located on the rear of the subwoofer and transmitter). The various switch settings change the digital identification code of the wireless signal the WT 50 sends to the subwoofer. The two switches must be set to the same position. Typically you’ll never need to adjust these switches. They are included in case you have more than one CPS Wi subwoofer in your house. Use differentWireless ID switch settings so the subwoofers won’t interfere with each other.

Note: Do not connect the same audio source to the subwoofer and WT 50 wireless transmitter at the same time.


Audio On/Auto/Mute

Plug the subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver. Set the audio switch to the desired setting.

AUDIO ON – The subwoofer audio is always on.

AUTO – The subwoofer audio will turn on whenever a signal is detected. If no signal is detected after several minutes, it will automatically enter the Mute mode.

MUTE – The subwoofer is muted and will not produce any sound. You may want to unplug your subwoofer if you will not be using it for some time or wish to conserve electricity. (On 230v models only, you may turn off the main power switch, located next to the power cord)

An LED indicator next to the Polarity switch indicates what mode the subwoofer is in:OFF – The subwoofer is unplugged (or the main power switch is off on 230v models)RED – Mute (No signal detected, Amp Off )

gREEN – Audio On (Signal detected, Amp On)

The subwoofer will automatically enter the Mute mode after several minutes when no signal is detected from your system. The subwoofer audio will then turn ON instantly when a signal is detected.

Polarity Control

(0° or 180°): Selects regular (0°) or inverted (180°) phase for the subwoofer. Set this switch to provide the fullest, most dynamic bass. The effect of phase will be most audible onlow-frequencypercussion instruments or music with a continuously repeating bass line.

Crossover Control

Adjusts the frequency of the low pass filter for the subwoofer. Note: This control is not active when using the LFE input jack.

Volume Control

Turn the subwoofer Volume control to the 11 o’clock position. If no sound emanates from the subwoofer, check theAC-linecord,Audio On switch,Power switch (on 230v models), and input cables.

Adjust the subwoofer Volume control until you hear a match between the main speaker and subwoofer. Bass response should not overpower the room but rather be adjusted so there is a natural blend across the entire musical range.


Maintenance and Service

All wiring connections should be inspected and cleaned or remade at least once a year.

If a problem does occur, make sure that all connections are properly made, secure and clean. If a problem occurs in one loudspeaker, rewire that speaker in a different location within the system. Should the problem persist then the problem is within the speaker. If the speaker sounds fine in the new position it is a strong indication of a more in depth issue with the electronics in the system. In the event that your speakers ever need service, contact your local Boston Acoustics dealer or visit for a list of dealers in your area.
