Acustimass 15 Subwoofer Not Working

I moved into a house and they left us a Bose Acoustimass 15 system. When I try to use it with my receiver, I get sound through the speakers, but nothing through the subwoofer. Its like the subwoofer is not even turning on. I know it is plugged in and turned on, but no sound through the subwoofer. Could there be an easy fix for the subwoofer or should I just order a replacement? Thanks

Could be the amp is burned out? Maybe that is why they left it. Not worth the effort to move

SOURCE: Bose Acoustimass Subwoofer not working; front/center are working

From the speaker output from your amp, connect left and right to the sub box. Turn on amp and try to play some music. If the sub is working, turn amp off and connect the satellite speakers and turn amp on. Make sure amp is on speaker "A" and the lines are coming from the same connectors on the rear of amp. Check your amp with another speaker to make sure it is working if you have no output. Does the Bose box have its own power cord (self-powered)? If it is self-powered, the internal amp might have tripped or is not working. If unit is not powered, the crossover or thermal protection could be damaged. Refer to Bose for parts.

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


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..

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.

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.

I have a Lifestyle 35 and want to replace head unit with a 5.1 receiver. The Bose subwoofer model LSPS uses a network type cable connector on the sub side and a male din plug on the head unit side of...


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.

How do I connect my Acoustimass® 5 Series III Stereo Speaker System to my Onkyo SR506 av receiver?


Well, first of all this speaker system is designed to give you a subwoofer where you do not have a sub-woofer output on your receiver/amp. However, that is not the case with the Onkyo. The way I would set it up (only because of the speakers you have) according to the Acoustimass Manual. You take the left and Right "Speaker" outputs to the Left and Right input on the Acoustimass and the speakers crossover does the rest. The Onkyo is designed to have a powered subwoofer so in this format you would just tell the receiver to turn off the sub channel which would tell the Onkyo to send the low end to LR. That should do it.

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.
