Hi all. I was wondering if someone out there might know how I can get my subwoofer to work when playing music. when I put in a cd, or play audio tracks from my PS3, the sub will not kick in. The manual has been little help, it just mentions that in stereo mode, you only get sound from the 2 front speakers, and possibly the subwoofer, depending on speaker setup. Well, it would have been nice if they elaborated on the speaker setup part, but I can't find it. Any help would be greatly appreciated. Thanks in advance. Dale.

2 things: It sounds like you are only playing CDs in straight stereo mode and not in a surround mode such as "pro-logic" or some other music mode that will engage all speakers including the sub. However if you prefer to only have sound for the 2 main speaker and the sub, you need to set your main speakers to "small" so that lower frequencies will be routed to the sub. Many receivers will also allow you to set the crossover frequency.

I agree with Mark-P. Check to see if your speakers are set to small or large in your receiver. Small means that the receiver sends signals to the sub under certain frequencies and large means no frequencies are sent to the sub from the speakers (in stereo mode). Also, be aware that a lot (most?) music does not have a whole lot of lower frequencies that need to go to the sub (some maybe, but not a whole lot, depending on your front speakers, of course).

Thanks, guys. I'll try the speaker settings tomorrow. I always thought the large and small settings were for if you had tower or bookshelf sized speakers. I'll let you know how it goes. Dale
