Teach me speakers setting on HK AVR320

Hi,

I own a HK AVR320 receiver and have some speaker setting questions. Hope you guys can shed some lights

This is my current setting on the receiver:
Left/Right : Large
Center : Small
Surround : Small
Subwoofer : Sub LFE + L/R
X-over Freq : 60Hz (this is the max freq I can set)

Here's my questions:
1.I understand that the VP150 freq response is from 85Hz to 22Khz. With my above setting, does it mean that I'll miss out all the center channel information ranging from 60Hz to 85Hz when watching movie? Will the subwoofer take care the low freq for center channel?

2. Do you have other recommendation to optimize the above setting? Shall I set all to large? I've read that it will harm the speakers if you send full range signals to non-fullrange speakers...you know, those Axioms (VP150 and M22ti) are my babies

It has to be taken care of to extend these speakers life span...

3.Does DD/DTS encoded movies typically send low freq signal to center channel (for the case above, signal information of less than 85Hz)?

Please advice.
Thanks.

TC, welcome. First, despite the size of your VR2s, you should set them "small" on your 320. They have fairly good bass on their own, but your KSW-12 is even better in the lowest bass and you should give it that responsibility by setting all speakers "small". Although your 320 gives you only 40Hz and 60Hz sub crossover choices when you set "large", with "small" you have 80Hz and 100Hz options and you should select 80Hz as the best compromise. The 60Hz setting you've been using is really a bit too low for the VP150; the frequencies under 85Hz aren't being totally lost, just rolled off from the sub, but the 60Hz setting does create a little weakness in that area and 80Hz will be better.

As far as the sub setting on the 320, when you set the VR2s "small" the setting is automatically "sub", which lets it handle the under 80Hz frequencies while all the speakers are rolled off below 80Hz by the 320. Turn the crossover control on the KSW-12 all the way up to the maximum frequency and leave it there to get it out of the way from interfering with the 80Hz crossover which the 320 is doing.

Yes, occasionally on movies the center channel does get low bass material under 85Hz, although dialog doesn't go lower than that. Good listening.

Your advice certainly make sense. Thanks!
