Bose Lifestyle 35 Accoustimass module rattles at high volume
Today my friends Accoustimass module tipped over and hit the wood floor pretty hard when we were hooking it up in his new house. When we finally got everything connected and turned it all on, we put in a DVD that had a THX sound demo at the beginning. When the bass tried to max out the sub starting crackling and breaking up. We had the volume at around 85 at that time. When we reduced it to 75 it hardly breaks up. But it seems to me it shouldn't even at the higher volume. Is it possible something got damaged when it fell over on the floor? Or is it likely that you can't run it at a volume of 85? He's had it for several years and had it in an apartment and probably hasn't typically had it over a 65 volume setting. It was my fault it fell over and I'm trying to determine if it broke today or if it's probably always been that way and he didn't know it.
Re: Bose Lifestyle 35 Accoustimass module rattles at high...
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, 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..
I had the same problem as this, but have lost my remote, so the system is know useles. Any way back to the point if you wiggle the cable around that goes in the speaker zone port then turn it off and back on then it should work :-D.
This is probably correct as modern equipment uses electronic volume controls rather than potential dividers the range is normally biased towards the bottom end so there is lots of the range that is quiet and a smaller part that is loud.
Unless you find that at the top of the volume range the system does not seem to be loud then it is probably correct. It is not uncommon for modern equipment to clip at 80 / 90% of the volume range. Where as old style equipment with volume pots used to clip at arround 30% of the volume range as it gave the apperance there was loads of extra volume available. In fact all that happened if you turned it up louder was it clipped more and more.
Sounds like you have a problem in the circuits, which of course would take an experience technician to find and repair. But a 1994 electronic item has pretty much reached the end of its expected life cycle (sadly, compared to older equipment which is still working great). Basically, it sounds like the power amp circuit is shutting down a few seconds after startup. Might check to make sure no speakers or cables have shorts, which could activate a protection shutdown circuit. If any of the cubes don't hiss when you turn it on, that would be the first place to look for a problem.
You dont have to crank up the volume to hear the bass man. It sounds like you have a bad connection some where. check all your connections and also if the wires are shinning and not dull at the connection point. having carbon or dust there will not help.
