I"ve taken a look at the Behringer amps - you are correct - the ones I looked at can handle 4 ohms bridged with no problem.
If I were to order an EP1500 - it will do 900 watts bridged into 8 ohms which would be perferct for getting the driver with dual 4 ohm coils wired in series. Driver is rated for 1000 watts so that seems really reasonable to me.
Or... I could order the driver with the 2 ohm voice coils and have a 4 ohm load - into which the EP1500 would deliver 1400 watts. This is a bit beyond the drivers max power rating - but I wonder if that is actually a bad thing.. as long as it is not contantly abused. I would think the driver could with stand an occasional peak of 1400 watts.. This Behringer EP1500 can be had for about $190 new online. Really reasonable. Any drawbacks to that unit vs. the EP2000 or EP2500 like you have?
