Question about Bose Acoustimass 6 III System

Bose Acoustimass 6 No Subwoofer sound

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.

Re: Bose Acoustimass 6 No Subwoofer sound

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.

Take it back for refund or exchange without delay. Too many times, there are cases of faulty factory assembly. Most likely a poorly connected wire inside sub, which fell off after a few booms.

I have a Bose Acoustimass 6 Series III the receiver is Yamaha 3066, this system is a 5.1 surround sound. Then I bought a pair of Bose 901 Series VI Direct/Reflective speaker system with active equaliz

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.

Unable to receive optimum output. The bass is totally flat !

Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.

Things You'll Need:

* Amplifier
* Speaker cable
* Extra subwoofer


Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.

Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.

Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.

Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.

If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..

Have a nice day..

Have this Bose system connected to my Yamaha a/v receiver

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.

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.

I am unable to get the required base sound from my Acoustimass 16

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.

Geiger counter sound from subwoofer

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.

Acoustimass Subwoofer has a low "hummm" sound when turned on.

Sounds like an inadequate ground wire in the signal cable. You may have to replace the cable between the reciever and bass module. It also, however, may be IN the bass or reciever module.
