Crossover testing

I have suspicions that the crossover and speaker size settings are not working on my 950. In 7 channel stereo, I can cycle through all of the crossover frequencies for my surround speakers and not really notice any difference in the bass from them. When switching from small to large I also don't notice much difference.

On my original 950 prior to this one, I seem to recall any change in crossover frequency was significant. The change now seems very subtle if at all.

Just curious if anyone else knows of a good way to verify the crossovers are working.

Thanks,
Scott

Try using the 5.1 or 6.1 "wide band pink noise" tests on the Avia test DVD. Wideband pink noise is a very sensitive way to hear changes in frequency filtering and levels. The test tone internal to the 950 is filtered pink noise with it's energy centered around 1,000Hz. There is no bass energy to speak of on this test signal. As far as I know, the Avia disc is the only one that has wide band pink noise, but I could be wrong.

If you use the Avia pink noise for calibration, be aware that you calibrate for a sound pressure level of 85db instead of the 75db that is standard elsewhere.
