Question about Boston Acoustics BA745 Computer Speakers

BA745 Boston subwoofer does not work

I just bought a replacement for my BA745 subwoofer, because I thought that I blew it out about a year ago. However now that I have plugged in the new one the subwoofer still doesn't work, the bass is non existent. Could it be the controller speaker? Is there a way to test that? it lights up and sound can be adjusted from it but it does not adjust the subwoofer. So do I have a subwoofer problem or some other problem?

Did you check to see if the subwoofer is receiving power?

It sounds more like the power supply is at fault (a filter capacitor dried up), but it'll take an oscilloscope to verify that - take it to a TV repair shop (if you can find one) or find a ham radio operator who still has test equipment. (If it happens even from an iPod, it'll be easy to troubleshoot, since the person doing it can use any audio source to cause the problem.)

SOURCE: I have no sound

Yes you must have the correct drivers installed. If you formatted your drive, you will most probably have to download all motherboard drivers also

SOURCE: Install Boston Acoustic speakers BA7800 to a new Imac?

Partial Solution anyway - I just got a Mac Pro (2.66 Nehalem )and couldn't find the manual from my old Gateway 700XL. This is what I did: Plug the green wire into the analog output, and the pink wire (if you really need an external mic, but you shouldn't since our new computers both have a built-in mic) into the analog input. Just ignore the black wire. You won't have the 2 surround speakers, but I'm still looking for a fix for that. I got tired of the crappy speakers in my new Apple Cinema display (the ONLY crappy thing about my new system). As you know, the sound from the BA7800 is great, even with just the two front speakers and sub-woofer. I'll keep you posted if/when I figure out how to set up the surround speakers! Likewise, if you hear something, please post here and I'll keep checking back.

I just took my sub apart and found that the surround on the driver speaker inside the sub was totally crumbled and lying in pieces throughout the sub box.

I'm looking around now for specs on the sub speaker so I can find a replacement.

How do i connect the boston BA745 comp. speakers to my gateway desktop?

Assuming you have the BA745 2.1 speaker set up, all of the cables connect to the subwoofer and then to the computer or the satellite speakers (these are built into the speakers IIRC). Take the cable with the black box (2 pins) to red and green. The red and green plugs go into the matching color ports on the computer and the pins on the black end fit into the jacks between the those for the two satellites. Plug the single end speaker cable into the subwoofer port all the way to the right on the back of the subwoofer. Plug the wire with the two plugs into the matching color jacks (blue to the left, red to the right). Then plug in the power adapter cable in the farthest left jack and plug in the other end to a surge protected power strip (that is plugged in and turned on).

The subwoofer isnt working but speakers are

You mean the right and left satellite speakers are working but the subwoofer is not. Try to adjust the bass control of the subwoofer at the back. Set it to full.
