Bought this system about a month ago. Was working fine until I noticed the base was no longer booming. On closer inspection I discovered there was no sound coming from the subwoofer on the Bose module. I doublechecked my cables, connections, checked through the menu for my receiver (Sony) and found no problem. The other mini bose apeakers work fine but absolutely nothing from the sub woofer. HELP! I'm about to drag it back to Circuit City but want to make sure it's nothing small that I've overlooked. Any advice will be appreciated.
We had the same problem, finally came to the conclusion the sub had blown,but then we thought we would check one last thing,even thought we had checked EVERYTHING, and we revered the speaker wire connections going to our reciever and that corrected the problem,the sub started sucking air and booming like it always did. sometimes its the simple things.

The setup is possible, but with several compromises. First off, to use the active equalizer, you'll need to insert this into one of the 2 channel AV channels limiting your listening with the equalizer to stereo only. The acoustimass subwoofer acts a driver/power regulator for the little cube speakers. It probably will not be able to drive the 901s at the correct level when attached to the Acoustimass unit as front left/right speakers. You could try running a dedicated set of speaker leads to the 901s which may work and still allow surround sound, but you'll lose the equalization capability on the 901s.
If you have it literally conencted the way you say not much good will happen.
The speaker OUTPUTs for the Yamaha feed the INPUTS on the Acoustimass Module then the satellites branch out of the Acoustimass Module's OUTPUTs.
Bose® recommends putting your Acoustimass module at the same end of the room as the
television monitor. To prevent interference, keep the module at least 2 feet (.6 m) from the
• You may hide the Acoustimass module behind or under furniture, but do not block the
opening. Be sure there is at least 2 inches (5 cm) between the opening and any surface.
• If the opening faces the wall it increases the bass; if it faces away it decreases the bass.
For the most bass response, place the opening 2 to 3 inches (5 to 8 cm) from a wall or
• Stand the Acoustimass module vertically or horizontally (Figure 6). To stand it on the
cable connection end, remove the cover by gently pulling it away
Move the sub closer to a wall or corner to increase the bass.
This is a SYSTEM and as such is not designed to be pieced out or separated. I don't recommend that you try it that way. I doubt it will improve the sound.
Clarify, did it ever work for you? Were both receivers used properly configured for the subwoofer? Did you also test the other speaker moduels running off the subwooferto see if they work?

Read the clues - Out of Phase means you have one or more of the speakers wired minus (-) to plus (+) instead of like pole to like pole. Having any speakers out of phase with their counterparts can **** the bass response out of the room. Check your wiring.
If it's a wireless system, the circuits are drifting off frequency or could be picking up interference from just about anything. If not wireless, you probably have a part (transistor or chip) inside that is developing noise by itself.
