KJDJ,

I spoke directly with Peavey on this prior to posting the first post above..

Basically.. I have what are as close to your SP7xx's

They are Bi-ampable and Peavey reccomends running them in this mode.

I get enough highs, it's more low end grunt I need.

The 15" fitted are the same as you find in the 215xt subs.. Black Widow drivers.

They require a crossover Freq of 150hz down.

Peavey say their 22xt is 40W rms and should not be run straight from a crossover, no matter what freq you set them to.
THey said they need CD equalization, which they told me is a FLAT frequency no boost etc.. this CD EQ stops them from being overdriven by certain frequencies.

Sounds to me a little like a compressor/limitier but for only specific freq bands.

I have a crossover that hasvery adjustable crossover points for hi, mid, low, sub.

Each channel has a level control also.. but Peavey said, without CD EQ they will blow!


Currently I run them in full range mode..

The 22xt acts as a mid - hi driver the 2 15"s are subs.. if I muffle the Horn you can't audiably here the 15"s but you can bloody well feel them [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]


I'm going to try peavey again,, and push them for some written info on how the CD EQ works as compared to non CD EQ.

It's funny as there are only a few of their range that specifically require CD EQ, most others can be run normally with any EQ / crossover you require.


Ultimately I want to run each set of dual 15"s from an amplifier each side. and run the two horn via the correct crossover/EQ from a single stereo amp.

Though the smallest amp I have is 750rms pr channel... [img]style_emoticons/<#EMO_DIR#>/huh.gif[/img] I think the comp/limiter will be used on the highs.


I'll re-post any info I can get on the inner workings of Peavey CD EQ theory.
