If anyone can help, it would be greatly appreciated!
I have a Bose Acoustimass 15 sound system (5.1) and Denon amp which have been working fine for the last 3 years.
A couple of weeks ago the subwoofer (SW) and rear left speaker (SL) stopped working.
Spent a couple of hours trying to fix it.
Have been through all the menu options etc and when i do a speaker test, its detected SW and SL but no noise comes out like before (the FR, FL, C and SR speakers are fine)
Ive checked all the wires / connections and reconnected just to be sure.
Ive also swapped a working speaker to the SL and still no noise emitted.
Ive also changed the fuse in the SW 3 pin plug and still no SW noise
Thanks for your time guys.

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
Instructions
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..
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.
Acoustimass module
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
television.
• 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
corner.
• 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.
The entire 5.1 amplification system, in the Bose Lifestyle 35, is actually part of the Bose Acoustimass (subwoofer) module. The RJ-45 (network type) connector passes a low-voltage signal from the console to the Acoustimass module. If you were to hack the connection, and plug the speaker outputs of a 5.1 receiver to the RJ-45 socket on the Acoustimass module, you would blow the amplifier.
If you are really itching to replace the Bose Lifestyle 35 console with a regular 5.1 receiver, I strongly suggest you sell your Bose system, and purchase a Bose speaker system, such as the Acoustimass 10 Home Theater Speaker System, which is made for use with a standard 5.1 surround sound receiver.
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?
Speaker Receiver setting
• Left and right LARGE
• Center LARGE
• Left and right surround LARGE
• Center surround* LARGE
• LFE/Subwoofer ON
With an Acoustimass 16 Series II system or upgraded Acoustimass 15 Series IlI system only.
I will try as best I can... There is no light on the unit. There is a two position switch, that's your on/off switch located on the botttom of the unit next to the pwr cord input... When the straight lined side is pushed down the unit is energized. When you pwr up the unit you should hear a light bump, not a cracking noise. There is a fuse on the main input/output board that is pretty easy to pop and swap.
Well to be hones 85 sounds pretty loud to me, generally the bose acoustimass module shouldnt really be distorting or crackling unless under extremely high sound levels.
It could possibley be that the speaker cone in the bass module has a slight perforation so it would distort at high levels. However other problems could be loose connections inside the unt or outside the unit. If your friend doesnt have it above 85 under normal circumstances I wouldnt worry to much about it but if there is a tear in the cone the problem could get worse.
Hi, I have just had the same problem and the advice from BOSE was to turn everything off and disconnect the sub from the main unit, wait 10 mins and turn everything back on, making sure to turn the sub on first.
As it happens i then noticed I had connected the sub via the BOSE link speakers plug to the main unit rather than the correct "MAIN" socket. - so if you are reading this you know I am a fool! But the sound now works.
Basically BOSE confirmed the reason for error 10 is that the main unit is not detecting the sub and speakers.
Anyway, I hope my foolish mistake, helps save time and blushes for anyone reading this link.
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.
