[QUOTE="wesleysh, post: 38764, member: 542712"] I think what you have is nice. Are you getting the full 1200 watts out of your JBL (400/sub)? From my experience and from the word on the grapevine the SQ won't be all that much better than the Perfect, and some say they prefer the Infinity's. Perfects are pretty nice. They do lack a little SPL though. Since that is what you would be upgrading by changing you would want to go with another JBL 1200.1. Because power handling will be the biggest difference with the new subs. I'm going to ramble now, I don't know all the math like SPL competitors do. You will be losing some displacement from cone area but increasing stroke. Since you will be working with only 1/3 less in cone area and doubling power, your SPL should at least double with the new subs and an additional JBL. Or something like that, lol.[IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] [/QUOTE]
