Introduction
Boston Acoustics Horizon Subwoofers
Thank you for choosing Boston Acoustics. The HPS 8Wi Horizon wireless subwoofer incorporates high-quality components
that produce the famous Boston sound. It is ideally suited for use in a high-quality 5.1 channel home theater or stereo music
system. The HPS 8Wi is capable of impressive deep bass and high output from a remarkably compact enclosure. In addition, it
features BassTrac®, a proprietary Boston-designed circuit that tracks the input signal to the subwoofer and prevents its ampli-
er from being driven into audible distortion. The bene t: the bass stays clean and strong at any listening level.
The HPS 8Wi also provides a wireless audio signal connection. This minimizes the number of cables in the system and allows
for easy placement anywhere in the room. You just need to plug it into an AC outlet.
The HPS 8Wi is designed to literally sound as good as it looks. With its elegant pro le and the soft smooth surfaces of its
cabinet, it complements the décor of any room and o ers no-compromise audio excellence.
Features
• 8” woofer
• 150 watts RMS
• Wireless audio connection to the subwoofer
• High-output front ring, rear ported design
• Deep Channel® Design (DCD) woofers for more bass from less ampli er power
• BassTrac® circuitry for tight, distortion-free bass at all output levels
• Adjustable polarity and gain control
• Removable foot
• Ultra-rigid reinforced cabinetry
• Soft-touch nish with color coordinated rubber trim

Unpacking
Carefully unpack the subwoofer and transmitter. 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.
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-o permits 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 di erent 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.
The foot on the bottom of the subwoofer can be removed to produce a slight backward tilt. Remove the thumbscrew from
the back of the foot to remove it. The screw is slotted for easy removal with a screwdriver or a coin.
IMPORTANT: Do not place the subwoofer where there is a chance of contact between the rear panel and drapes or furniture.

Connections
After the subwoofer is placed you can make the audio and power connections. The wirelss transmitter lets you deliver the
audio signal to the subwoofer with a minimum amount of cable. However audio signal cables can also be connected directly
to the subwoofer if you prefer.
NOTE: Power is always supplied to the subwoofer electronics unless it is unplugged or switched to the o position using the
power switch located on the rear panel. The auto-on circuitry only activates or deactivates the power ampli er. Make sure
your subwoofer and receiver are unplugged when making the connection.
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. These on board electrical outlets do not o er the amount of current
or proper isolation required by a power ampli er, such as the one in your ampli er.
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 “5V DC”.
Line level or LFE: On most systems use the line level in or the LFE input. These inputs accept the line-level signal 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-frequency (LFE)
information (such as explosions and thunder) contained in digitally-encoded soundtracks.
Select ”subwoofer-yes” from your receiver’s set-up menu. Hooked up this way, the receiver’s ampli er is relieved of having to
reproduce the di cult 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 AUX input of the
transmitter or the LFE input on the subwoofer.

Connecting to Electronics Without a Subwoofer Output
If the electronic in your system does not have a subwoofer of LFE output you can connect the HPS 8Wi to a preamp output.
Use a stereo RCA cable (not included) to connect the preamp outputs to the Left and Right inputs of the transmitter or the
subwoofer.

Adjusting the Crossover Control
When using the Line Level inputs (not the LFE input) the subwoofer’s built-in crossover 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-tune
the 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
Wireless ID Switches
Both the Subwoofer and Transmitter have Wireless ID switches. The various switch settings change frequency of the wireless
signal the Transmitter 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 so that, if you have more than one HPS 8Wi in your house you can use di erent
Wireless ID switch settings so the subwoofers won’t interfere with each other.
Operation
Power On/Auto/Standby
Plug the subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver. Set the Power switch on
the subwoofer to the desired setting.
OFF – The subwoofer is o and will not produce any sound. You may want to turn your subwoofer o if you will not be using
it for some time or wish to conserve electricity.
AUTO – The subwoofer will power on whenever a signal is detected. If no signal is detected after several minutes, it will auto-
matically enter the Standby mode.
ON – The subwoofer is always on.
An LED indicator between the Power switch and the Polarity switch indicates what mode the subwoofer is in.
OFF – The subwoofer is o
RED – STANDBY (No signal detected, Amp O )
GREEN – ON (Signal detected, Amp On)
The subwoofer will automatically enter the Standby mode after several minutes when no signal is detected from your system.
The subwoofer will then power ON instantly when a signal is detected.
Volume Control
Turn the subwoofer Volume control to the 11 o’clock position. If no sound emanates from the subwoofer, check the AC-line
cord, Power switch, and input cables. (Are the connectors on the cables making proper contact? Is the AC-line cord connect-
ed to a “live” receptacle, is the subwoofer in either the Auto or On position?)
Adjust the subwoofer Volum e 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.

Polarity Control
(0° or 180°): Selects regular (0°) or inverted (180°) phase for the subwoofer. Set this switch to provide the fullest, most dy-
namic bass. The e ect of phase will be most audible on low-frequency percussion instruments or music with a continuously
repeating bass line.
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 di erent location within the system. Should the problem persist then the problem is
within the speaker. If the speaker sounds ne 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 www.bostonacoustics.com/dealers for a list of dealers in your area.
