Bose Acoustimass 15 Series II subwoofer not working

The system is just a year old and the subwoofer has stopped working; the remaining five small speakers are working fine. About six months ago it did the same but the sound came back when i moved the subwoofer by tilting it. The same procedure didn't work the second time the sound quit on me.

Has anyone else come across this problem? Would love to hear of it and the steps taken to resolve the problem

SOURCE: Bose Acoustimass 6 No Subwoofer sound

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.

SOURCE: 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.

SOURCE: BOSE ACOUSTIMASS SYSTEM 15 SUBWOOFER - NO POWER

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.

All I did was unplug my surge protecter for a 1 minute and once I did that I had bass from the module again.  I am using a Belkin PURE AV power console.

I aquired Bose Acoustimass 15 surround sound through home purchase. Hooked wires up to reciever and hdmi to tv and i got nothing. my question is, how do you turn on the sub? just plug it in?


Hey Any chance you have the Acoustimass 15 II or III? The first Acoustimass 15 has a switch. The II and II models turn off and on when it receives a signal from the source you are using. Amplifier, ect. All you need to do is make sure everything hooked up correctly and plug it in.

How do i use my ipod to play through my 12 year old Bose Acoustimass series 5 system


You don't connect an Ipod directly to any unpowered speakers since they need an amplifier between them and your source. Presumably, your speakers already have an amp source? Then what you need to know is how to connect the Ipod to the amp. Without specifics, I can only offer general advice. Get an adapter for the Ipod headphone it to make it compatible with either an RCA input or a headphone jack.

Can I connect my Bose Acoustimass 5 - Series II to Bravia unit?


Yes, there should be no issues using your Bose speakers with your Sony receiver. Sony has a "hookup guide" to help here -
