I've got the 250watt plate amp from parts express and I was doing some experimenting with it the other day. Here's my equimpent:
Denon 1802 (80hz crossover)
2 Le Amps
PE 250w plate for my sub
nOrh 4.0's all around
DIY 340L EBS Tempest (sonotube)
I was trying to see how my nOrh's sounded crossed over at 60hz. So I took the preouts from my receiver into my Le Amps and then into the high level in on the plate amp. I hooked the nOrh's up to the high level out. So I figured if I crossed the plate amp over to 60hz this should work right? Well, the bass from my subwoofer dropped to about nothing, and the nOrh's sounded about the same. Just out of curiousity I played some test tones from 100z to 600hz and I could still hear a 600hz tone from my sub loud and clear with the nOrh's shut off and the plate amp crossed at 40z. I was like man that sucks. So I decided to see if the crossover in my receiver's any better. So I hooked the plate amp up to my sub out in my receiver and set the crossover to max and I could still hear 250hz fairly well, but defintely nothing at 600hz. Then I crossed over my plate amp to 40hz (now double crossed) and I couldn't hear anything above 160hz, which seemed a whole lot better to me. But now I'm losing like half my signal through crossovers. So now I'm starting to look at preamps with good hi-pass and low-pass crossovers. Norh is coming out with one that's looking like just what I need for around $700. If I hook up my sub to the low-pass at like 60hz does that mean everything else will come out of the high-pass. If so, then why do they allow high-pass crossover settings from 1.2khz to 3khz. This would seem like I'd be missing everyting from 60hz-1.2khz. They also have a set of full range outputs, so would I use those. Sorry for all the questions guys, I'd just really like to understand all this for once :b
