introduction
Congratulations, and thank you for purchasing an a/d/s/ powered subwoofer. The culmination of
years of acoustic research, these subwoofers are designed to flawlessly reproduce the lowest
octaves of music and to add incredible impact and realism to movie soundtracks, while perfectly
complimenting a/d/s C-series and H-series loudspeakers. Please read this manual carefully to fully
understand and maximize the performance of your a/d/s system, and to enjoy years of superb
musical and home theater sound reproduction.
Be sure to save your sales receipt. It is your best record of the date of purchase, which is required
for warranty service.
Read and follow all cautions, warnings and notes.
cautions
WARNING
To reduce the risk of electric shock, do not remove any parts of the speaker. There are no user
serviceable parts inside. If service is required have it performed by a qualified service
professional.
WARNING
To help prevent electric shock, connect the speaker using the power cable into properly
grounded electrical outlets. These cables are equipped with 3-prong plugs to help ensure proper
grounding. Do not use adapter plugs or remove the grounding prong from a cable.
WARNING
To help prevent fire or shock hazard, do not expose the speakers to rain or submerge in water.
The speakers should be situated away from heat sources such as radiators, heat registers, stoves
or other heat sources. Be sure all the components in the system are turned off while making
audio and power connections.
