OK, so here's an update.
1st I still haven't had the time to get in touch with your friend Marty, but I will.
I did take the whole rig to a company I work with and is an authorized Peavey repair depot and we've determined my x-over is a POS! As much as I am embarrased to admit it was/is a Behringer that I bought from a company I worked with years ago doing sound and they swore it was the shiznit, WRONG!
It's output is crap and you CANNOT get an even signal to the highs and lows. In running my white noise through my rig, I ahve to turn the high output on the x-over all the way down and it's still sending the amps into clipping while I boost the low output and barely flicker my -10 lights UGH!
There is very little sensitivity in this piece of garbage and big adjustments make very little difference, it's certainly not a precise piece of gear.
It is very clear why now I've popped 4 BW18's in a year or so when in the past 15 years I'd blown them 1x and that was actually after a winter event, I didn't let them properly cool and loaded into the trailer and they crystalized.
Also, I've noticed that that x-over really colors the sound and all but kills the vocal range regardless of the x-over freq. Remove the x-over from the chain and BAM, power.
I've attached a few pics for your viewing pleasure. In pic 007 you'll notice the highs 100% cut and the lows 100% boosted on the x-over and look at the 2nd amp, the lows are barely lighting the -20 signal LED's and the high are throwing the LED's into solid clipping. I even boosted the lower frequencies on the eq and still couldn't get much input.
In pic 009, you'll notice the high and low output are the same, now take a look at the signal LED's on the amps
These were taken with no speakers attached and -9db white noise. All cables are good and checked out, entire signal chain is balanced and matching cables.
I had the DRPA and really never liked it but I think maybe it's because I expected it to work magically and I expected too much from it with not putting much into it. So I sold it and as a result KILLED 4 subs
Now it's onto looking into the VSX, I jsut want to find one locally I can play with before I buy.
Marty, in regards to replacing an 1801 with an 1808, where can I get the info to see how well they're matched to my SP118 cabs? I do like the idea of higher power capability but not at a cost of robbing me of sound quality. I'm wondering if they're close enough of a match to use or not.
