Acoustimass 15 subwoofer

[db113]

Im new to home theater and apparently have already committed the cardinal sin of buying Bose speakers. At least I bought a used set of Bose Acoustimass 15 and paid about one quarter of the price of a new set. I also bought a Yamaha RX-V2500 receiver (130 w x 7). Is it possible to use the Acoustimass subwoffer w/o using the special wiring that came with the speakers. My room is already wired with standard speaker cable and I would like to us ethe Acoustimass subwoffer with the standard speaker wiring. If this is not possible, could someone recommend a subwoofer that would work well with the Yamaha receiver.
Thanks,
db113

You made a mistake buying them. Don't compound it by using them.

You can probably use normal wiring with the Bose subwoofer, but I don't know if you would need to modify it.

You could build yourself a nice subwoofer!

Just looked at the B*$e web site & found their Acoustimass 15 manual. Looks like you should just be able to plug in the RCA jack on the funky cord to the LFE output on the receiver, but you will need the cord from receiver --> sub (or cobble your own for the LFE).

Good luck!

BTW, don't worry about the "sin". I stumbled across diyaudio a couple of years ago when I was looking to buy B*$e, 'cuz of course they're the best . (But not before I'd spent $300 on some other speakers that are now acting as doorstops).

P.S. - The individual double cube speakers go for $75 - $150 each on ebay... If you liked the sub, you could keep it, sell the cubes!

The bose sub and speakers pretty much go together, because the subwoofer probably has high pass filtering for the cubes so that they don't start to sound like they're farting, and then catch on fire at high levels.

the "subwoofer" is actually not techinically a subwoofer because of its frequency range. that is why its called a bass module by bose.

it will play very high as it doesnt have an adequate crossover for a subwoofer. so, you will get voices through it unless you send it an appropriate bass signal from the preamp or whatever.

you might be best off selling it all and doing some DIY (i assume that's why you are here).

Neither are most so called subs on the market

One of the truest things they have ever said to their customers.

Pretty awful isn't it?

Now there's some sage advice.

i once thought of getting one of the passive bass moduals on ebay and adding a plate amp to see what would happen...

oh oh i just remembered, something...
back in '95 or '97 or something, my aunt got a adcom preamp, amp, amd cd changer, and a bose acoustimass 2.1 system, she asked me to hook it all up and so i did... it sounded all right till i put the bass outlaws
"illegal bass" cd in the player. i in my entire life have i ever heard that much distortion at such a low volume. i barely turned up the volume and it sounded like a a bunch of fast farts... put culture club in and it sounded all right again, bass outlaws, crap... i left so sickened

A buddy of mine inherited one, we did just that with my PE plate amp. IIRC It was the 2.1 system, there were no surrounds or place on the 'module' for them.

Horrible dips and peaks with a slow sine sweep. Sounds like its bandpassed by enclosure or passive xo.
