If you have 4 IPAL's you might be able to series them, and power those with a single fp14k in stereo mode.
Not sure how "happy" the amp would be driving singles on each channel, or a pair on 1 side only...
In any case, if the clone dies, then you'll have to step it up to 2 or 4 of beefiest SpeakerPower amps you can afford.
From an excursion, cooling and cone-area perspective, you are much better off with 8 $200 B&C's and 2 fp20k's, than trying to power some silly $1200 0-ohm B&C if you want to "get loud". But that's just my opinion.
Heck a single 20k could power 8 B&C if they were all 8-ohm, paralleled down to quad 4-ohm if you had to.
The amount of power you can extract from 2RU these days is pretty nutty; yeah it's not unbreakable, but still...
16 B&C's and 2 20k's in 4RU... yes please!
Just keep in mind that the 14k needs 240V 15a and the 20k needs 240V 30a;
or double that for 120V...
If you need PFC (for say a genny) then you'll have to buy PowerSoft K/X or iTech's, or Gruppen PLM's.
iNukes, FP's and SpeakerPower doesn't have it.
