Hello I have dual Infinity Perfect 12.1 waiting to build a box for. Going to do the 4cf tuned at 19 hz. Or should I go with the Dayton Classic 15's in a dual setup? I have a Crown 402 and a Crowns 602 that I could use for power. Not looking for loudest, just a nice clean sound with a good bottom sound. It would cost more for the 15s but would it really be worth it? I would love to do a CSS dual 12's with 4 passive radiatiors.....overKill???
