Hi, I'm looking for 2x 10" sub, I was looking for some Infinity kappa perfect 10dvq but I was wondering if there is something better than these for the same price, I buying on ebay, so they are 150 each... I'm looking into great sub with tight respond and that have power too(I will powered them with an old school amp of 300 rms). I've look also to Treo TSX 10.44 and some other brand like RE, phoenix gold, CDT...? Thank you!
