Ok, my tym is short so i'll just give you my quick 1st impressions....... DAAAIIING!! Now my prior setup was a RF P2 sealed so it's really no comparo i guess, but if you are looking for a nice ,tight,clean,accurate sounding sub that can still rattle your eyeballs ,,go for this setup. (IMO) I put on sum T.I. cant remember the "song" but i used it because the RF just couldnt stay accurate with it.For sum reason it would always get sloppy. I tried a couple other subs and they did the same to different degrees. The Icon on the other and was accurate at a MUCH much higher output level... it just pounded harder and harder the more you cranked it. Sweet! Now i have to upgrade my front stage to stay up wit hthis,,,so the cycle continues. BTW: Enclosure quality was top notch, highly recommend. i'll do pix and more input as i have tym.
