That's what I thought at first as well.

Consequently, with my old 950, I put the crossover at 80 Hz. Then later, I tried 60 Hz and found I liked the sound better. Then much later, I subsequently put the crossover at 40 Hz just to see what it was like, and found I like the sound even better. This is for 2 channel stereo mode. Admittedly, I did not hear that much of an improvement going from 60 to 40 in some of the multichannel modes like DTS NEO 6. But I do think there was a significant improvement in going from 60 to 40 Hz in stereo -- note the subwoofer is still active in stereo mode in the 950 since the mains are set to small.

My mains are Von Schweikert VR 4 Gen II's.

I did not like what happened with the center channel when I lowered its crossover frequency. When the center channel crossover was lowered, the center channel speaker, which sits on top of the RPTV, sounded a bit boomy. I am not done experimenting with it, though.

My center is a small Von Schweikert speaker center.
