Sweet subs for the money. Just as loud as your L7', but sound a little better and cost way less. Look around and you can get a pair for $300 shipped to your door. Can't beat that if ya ask me.
2 Massive CW15s. i would watch the gain just a tad but u want lows, these will give em to you especially at 34hz. i had my 12s in a 34hz box an it was nasty. u would seriously not be dissapointed. an for 450 shipped for the pair you will be happy an have money left over
