i recently inherited a pair of infinity Kappa 9 speakers. im in search of an amplifier to power them. my budget is low and im using my sansui 9090DB as a preamp. my budget is low for one because these speakers came as a surprise and i didnt know anything about them except i've wanted them since i was a kid. i was shocked to say the least when i discovered my 9090DB wouldn't power them :) i found out real quick that i was in a whole new league. I've got a lead on a Crown (dont kill me) XLS 2000 for $350, here are the specs:
All @ .05% THD Crown XLS 2000
Stereo, 2 ohms (per ch.) 775W
Stereo, 4 ohms (per ch.) 525W
Stereo, 8 ohms (per ch.) 300W
Bridge-Mono, 8 ohms 1050W
Bridge-Mono, 4 ohms 1550W
does anyone have any real objection to using this amp to run both speakers in extended mode? i figure it's enough of a powerhouse. for those of you that don't know, the infinity kappa 9's will go a little below 1 ohm at two frequencies. 33hz and 7k. the guy at crown *said* this amp would handle the interrmittent drop in impedance. should i be worried with crown? is there anything else i should be looking at in the $500 range? again, i know my budget isnt much but i couldnt see why this amp wouldn't do the job unless it sounds horribly bad. any advice? again the kappa 9's will hit .8ohm at two frequencies even though infinity specs then at 4-6 ohms and 60-340W rms. i've been told the amp needs to double up power effectively as the impedance drops. thanks.
