Im in the procss of building a DIY sub, in a 6.9 cu ft^3 enclosure, using an Ascendant Audio Arsenal 12", tuned to 21 hz, I am looking at doing a seperate amp. I do not want to use a box amp because I want the sub to look as discrete as possible. I am looking at Behringer A500 or EP1500, or any other suggestions. The AA Arsenal is a dual 4 Ohm, with a RMS of 750 watts, and a rec power of 500 watts. Im up for used or new, so any ideas are welcome. Thanks.

I personally use an EP2500 thats 750 X 2 into 4 ohms. A lot of people are using NADY amps and reporting good results at low prices. I believe they make on that will 700 mono into 4 ohms for about $150.00.

From what I hear as of late, pro amps seem the way to go. Carvin, Nady, QSC, Samson, BEHRINGER & Crown have been mentioned.

Nady is what I'm looking at too. 675 watts mono at 4 ohms will do plenty for many I think. I plan to move it to my mains in the future if I feel the need to upgrade my sub setup. It does 200w/ch at 8 ohm stereo.

I've been using a Peavey CS-800 leftover from my band days. 2x400W into 4 ohms. both channels can be bridged for 1x800W into 2 ohms. I have a 2-driver pseudo horn sub. Don't know the the other specs, but it's been a workhorse. I also put my Rane active crossover in front of it (also a leftover).

I hate to tell you this, but a 7 cu. ft. sub is never going to be 'discrete'. :D

Ok, maybe discrete wasn't the best word, more like clean.....so its going into a corner the speaker wire will be right behind it so you wont see it. I did some measurements with WINisd and at an f3 it will do 115 db at 19 hz...not bad for a $300 sub total....

Crown amps are about as good as you can get for subs. I've been using them for years, and they are very reliable and powerful. Crown has the highest dampening factor of any amp made, and this is crucial for good sub performance. You should look for used Crown CT models like the CT-400/410 for CT-800/810. They are two channel amps that you can bridge. You'd get 400 or 800 watts respectively. They are also THX certified if that matters to you...

If you really want a killer sub amp, look for a Crown K1 or K2. They are amazing for subs.
