: : I use a Carvin bi-amp head which is 2x250 watts at 4ohm with 2 4x10 8 ohmes each(Eminance speakers)

: Carvin has a 1-800 tech line, give 'em a call, maybe they can
: Are you sure about that? Doesn't two 8 ohm cabs give an overall 4 ohm load for the amp?
If I'm reading the original post right, I think this Carvin head actually
has a two separate amps putting out 250 watts each at 4 ohms per side..
My Eden WT-800 is like this, 400W + 400W @4ohms....If you run 8 ohm
loads (speakers) on a amplifier rated for 4 ohms (in this case 2 separate
amplifiers) the Amps are not operating at rated output (in watts), and
therefore not as efficiently, probably at about HALF the claimed amount
of watts...Maybe some of the more technical list members can clear
this up, or as I suggested, Carvin has a help line that you can call
for more info....Still, I don't think the distortion problem rests
solely with the speakers themselves...
