Just sold my Xenon so I'm gonna need a replacement asap. I have some Diamond 12" D6's. I liked how they sounded at 800 watts to both, but I know they will shine with 1400-1600. I've considered a Diamond D6 1500.1, I can get it authorized at around 550, possibly a nine.1 ( although i don't like how its only 64% efficient, unless the site is wrong), and maybe an MD2. if you guys got suggestions that'd be great, anything in the 400-500 range that will push these d6's.
