$400 Budget - Need SQ System 10"

[the_franchise 10+ year member]

I have a Matrix Elite 10... Excellent Subwoofer! I've owned a lot of different subs (type r, xxx,, kappa, 3510, stroker, hx2, cvt, 11Ov2, 10w7) and it kicks ***... I was going to sell it at one point, but when people get in and hear my system i love to hear them say "I've never heard of that before, but I want one!". Would fit perfectly in a SQ system, but don't think it can't bring the noise! I'm actually looking for another 10... My buddy had a Power ME15... all i can say is... ****!
