Recently purchased a house with has Yamaha SW 3 subwoofer and speakers. I hooked it up to my RCA surround sound system receiver (per the Yamaha manual) and nothing is coming out of the subwoofer.

have u checked that the sub option on the reciver is on?

Had the same problem with KLH E-10D Preamped Subwoofer. Afte brief research, I found the problem was with my Pioneer VSX-D509S reciever settings, not the subwoofer. If you have the same reciever, you can go to the pioneer website to download specific model owner's manuals.

Select your Pioneer reciever model and it will give you an option to download the pdf manual. Hope this helps.

I have the same setup. Are you going out of the subwoofer output of the reciever? (it's purple.) then into the LFE jack of the subwoofer (also purple.) That's the only connection you need besides power. If you have those right, try using your cable for something else to make sure the cable is good. Is the indicator of the subwoofer green? Mine comes on with the reciever. Good luck!

SOURCE: The subwoofer is not working on our Bose 5.1 surround speakers.

First of all you should never indicate speakers as Large unless they can produce below 20Hz (which is very low), otherwise always set your speakers to Small.

Second, did you also indicate in teh setupmenu that you have a subwoofer? Because if all speakers are set to Large some receivers will omit a subwoofer because Large indicates the speakers can reproduce all sounds even below 20Hz.

So walk through your setup menu, say YES when the sub (SFW) is asked for and that should do the trick.

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.

Testimonial: "Thanks for the respond. Very good info - will try as you have suggested."
