Hey ya'll! As alluded to above, i've recenly put together an Avalon U5/RNC 1773/Crown/Eden rig. Sounds lovely at around-the-house practicing level, sounds even better through the PA, but while at rehearsal the other night (moderately loud guitar, miked sax, enthusistic drummer) I noticed some serious breakup on the lowest three notes on my E string. In comparison, my previous set up was a GK 700RB + RNC 1773 + BBE 482i + 410XLT, which was loud as hell and had more booty than I new what to do with. All that's change is the absence of the BBE and the addition of the U5/Crown. What do you think the problem is? The drivers in my cab are fine, I have substantially more headroom now (600w per side into 4ohms, only use one currently) than before (700RB=380w into 4ohms)... That's supposed to help clearer low end reproduction, right? It occurs to me that I may be overdriving the U5 due to a lack of sufficient gain to drive the Crown, though I haven't found anything on here which supports that. Or ist it that the XL 602 isn't cut out for a bass rig? (To all PLX advocates: I'd love one but they cost a fortune in Oz...) Thanks for your time!
