yes you can put a crossover at the speaker using chokes and capacitors, and build them to the freq and Q you desire

Maybe you have a better idea, the amp has the ranges of:
HPF (High-Pass Filter): 50Hz - 1kHz
Full: 15Hz - 30kHz
LPF (Low-Pass Filter): 30Hz - 500Hz

I want to set both channels up to my subs so what if i put a crossover before the sub that only let something like 200hz or below pass (10 and 12 inch subs) then set the range to 15-30000hz. That would give the subs a signal of 15-200 hz, right?

Also, for a 10 and 12 inch sub what would you recommend the LPF should be at? 200 was a guess. (already have 6 inch speakers for medium sounds)

Thnx

why're you using 2 different sized subs? when doing this they should each have their own amp and wiring.

Well, I was using 2 subs because from what I understand a 12 inch provides deeper noise but a 10inch plays at lower levels of volume, i thought it might provide a little of both worlds. And the amp is 2 channels so i thought I could hook them both up, am I inncorrect? (2000 wt peak and the subs are close to 2500 when combined so it should stress them too much)

Thnx for being patient :)

plus.. you'll want to set your filter lower then that..

IF (And i don't reccomend) you use a 10 and a 12, you should look into seperate amps and then set the filters at different levels.

your understanding of subs is incorrect.
use a single 12" sub, or a pair of them.
set the crossover at 60Hz
port the enclosure and tune it to about 34Hz.
use good subs with good motor control, and give them ample power to control the cone movement.
you'll have plenty of deep, well controlled, tight bass.

Alright, so I want to use the same size subs, right?

If I used a pair/single 10" I would want a what hz crossover?

What if i used a pair/single 12"?

Also, what is the difference between a "active" and "passive" crossover? Thanks

yay, I was hoping kiki would step in and fill in for me. :) (that came out wrong, made it sound like i know as much/more than kiki--NOT TRUE lol)

ANYWAY, I'm going to make a topic about slot porting. Kiki, if you would, would you please respond Thanks for your time!!

passive and active is explained on http://www.bcae1.com under teh crossover sections.
easier than retyping it all here again. if ya still need help on it after that site, tell me.

eh for a twelve, I'd say about 60Hz
for a ten, maybe 80Hz.

Thanks, also.. is it possible to run a 3240234023400 watt amp on a 1000 watt speaker with some type of resistor between the amp and the speaker? Thanks :)
