I've owned the punch HX2 and on a scale of 1-10, I'd give it about a 7...It was pretty loud, but it was not the best SQ sub i've ever owned...I deal with the MXS subs at work and this is deffinately the best overall sub I've seen in the store...for the price point, it is very accurate and very loud...my experience with the Kicker sub is a bit more limited as I don't sell them, but from what I've seen I have not been very impressed-very loud, but very sloppy --i'd go with the 7500/MXS that's just my opinion take it as you wish--later
