Hey all,

I have this surround setup -- and am extremely happy with it:

http://cerwinvega.co....ies/avs51.html

Now, My question is -- I am trying to properly set the crossover in the receiver, and I want to find out what the Hz range is for the main loudspeakers. The spec sheet give an over all range -- but that includes the sub which starts at 35Hz -- so that doesn't help... I would like to find out so i can set my xover to about 10Hz above the lowest limit of the mains.... if i called the company, would they have those specs?

Thanks,

Matt

With a 4" driver, I'd say it's safe to say they are somewhere between 80Hz and 100Hz. You don't want to set your x-over so close to that point because the speaker will roll off quicker than the x-over will, creating a gap/dip. I'd try a 100Hz or 120Hz x-over.

The easiest way to find out is to get Avia or VE and run the singnal sweep for your speakers. When they drop off, you know you reached the limit.
I know what I like when I hear it

you could use a spl meter and some test tones to determine where they roll off at and to find a good crossover point.

VE doesn't have a signal sweep, or do you mean DVE?
