Hello everyone. I need help to set up my system:
- One Peavey amp CS 400 to run 2 passive sub peavey Subcompact SP 18
# Frequency Response: 47 Hz to 190 Hz (-3 dB)
# Low Frequency Cut-off (-3 dB): 47 Hz
# Usable Low Frequency limit (-10 dB point): 39 Hz
# Power Handling: 350 W continuous, 700 W program, 1,400 W peak
# Max Sound Pressure Level: 122 dB SPL (cont.), 128 dB SPL (peak)
# Impedance (Z): Full Range Nominal is 8 ½
- One pair of Mavkie active SA 1521 specified as : http://mackie.com/pdf/sa1521_ss.pdf
- Mackie mixer Onyx 1220
- DBX Drive rack PA
I understand that I should set everthing as custom amp, custom speakers... Please help me on the cross over and EQ.
I also bought a DBX RTA mic. From the advice that I read from this forum, I set up my gear in my garage today, trying to pin the gear to have a general set up. Where do I put the mic ? How far it would be from the mic to the speaker. Someone in this forum said I should point the mic just to ONE stack and down to the floor. What is that mean?
Being as a newbie and with my language barrier, please help me. I 've read every day since I 've bought the DVD Drive Rack PA but still be without a clue. Please step by step and help me.

Subs: set a Hi-pass filter about 50 - 55 hz with a BW 18 slope
set a Lo-pass filter at 90 hz with a LR 24 slope
Mackie's: set a Hi-pass filter at 90 hz with a LR 24 slope
Do this and report back. DO NOT ATTEMPT TO AUTO EQ, YET.

So I should have a more power amp for theses sub.? Which one would you recommand?
I will play with the limmitter things but I could wait to buy the right amp for my system. All of your inputs would be very helpfully.
updated: a friend just let me borrow his peavey amp PV 500__Could I run each amp for one sub? Then what adapter should I get to divide signal to both amp. Any problem if I do this
Even bridging the 2 amps that you have only gives you 400 and 450 watts per speaker. To use the 2 amps and avoid having to use an adaptor (being a newbie) just set up the subs as stereo and use the L & R Lo outputs.
