Hello everybody! Thanks to the knowledge of this forum I have purchased and am waiting on a tech 21 vt bass deluxe.now it's time to get some POWER! I currently have an ampeg 810e (800w @4 ohms/ ~58hz-5khz) and a hartke 215xl sub module (400w @4 ohms/ 30hz-2.5khz). I use a passive peavey grind 5 Now for the questions. I've noticed the 810 (my constant cabinet) is a little lacking in the low end balls, but I love the responsiveness and punch that the sealed cabinet has. Since I already have a hartke 215xl, I figure hey, use it like a sub! So my next purchase will be a power amp of sorts and I'm thinking crossover (variable) would be the best way to run mix matched cabs. My big problem is wattage.my original thought was something about 400w so I don't destroy the 215 when I use them both and just match the other side. Then maybe use the 810 with the amp bridged when using it solo? The crown xls's stood out a bit to me, but I'm really unsure which power rating to get. Sorry for the lengthy post, but I figured as much information as possible would probably only help. Thanks in advance!
