I have a JBL L8400P. I got it in April 2009 and it just had its third failure. The first was a melted voice coil and the second was a friend amp. Now, it goes out of stand-by, then immediately back in, which makes me think a capacitor failed, but haven't taken it apart yet. So my question is repair or replace and with what? There are no service centers nearby and I'm afraid that this is just an unreliable model that will fail again in a couple years if I fix it. My room is 15' wide and 13' deep with 10' ceilings. The rest of the set-up is a pair of JBL L890s, an LC2 and two pairs of L820s with a Denon AVRX2100W receiver. I'd liek to keep the budget below $1000. A lo t below if possible. Would I be better off getting one sub that uses my whole budget or a pair of cheaper subs?
