    it is the built in tone test on the receiver that I am using. The receiver is a RCA RT2300. Manual at http://download.ethomson.com/english...B/55021630.pdf the subwoofer is a mtx sw2 12 inch 100 watt sub. If I turn the volume way up on the receiver I can hear the subwoofer noise during the test but it isnt nearly the same level as the other speakers. But when I watch a movie there is plenty of bass. When I am watching TV in stereo mode(digital optical input) there is way too much bass, and when I watch TV in pro logic mode there isnt enough bass.

    Not sure on that piece of equipment why this would be. I think only an upgrade is going to help you much here at all.

    I was looking at my subwoofer owner manual and it says to run the preamp out to one of the 2 inputs on the sub, but I have been using a y-adapter to connect it. when I take the y-adapter off, stereo mode sounds more like it should. could that be the problem?? am I not suppost to use a y-adapter?

    Many times the pink-noise does not send signal to the subwoofer. All my Yamaha recievers skip the woofer.

    You need a setup dvd like the Sound and Vision disk ($20) or Video Essentials or Avia.

    If you have a CD rom burner you can make your own test-tone cd using a tool like "NCH Test Tone Generator"

    No. There IS some good software in the $100 range that can do a lot of interesting stuff. But you usually have to add a calibrated microphone ($200) to get it to measure things with any accuracy.

    The $45 SPL meter from Radio Shack is a fairly inexpensive tool most of us have.

    Well it is a DVD, so I would assume it does just that.
