One thing that seems to be often overlooked about some of these new amps is their crossover specs. Many of them make numerous references to having a built-in crossover, but you have to dig into the manuals to see what you're really getting.

Peavey IPR: "100 Hz switchable 2nd order High pass and 3rd order Low Pass per channel"

Carvin HD1500: "Each channel has a third order (18DB/oct)100Hz Low pass filter subwoofer crossover" ... "BIAMPING must use an electronic crossover or speaker management system to SEPARATE HIGH AND LOW FREQUENCIES"

Crown XLS Drivecore Series: "the crossover frequency is completely variable allowing the choice of any crossover point between 50Hz and 3kHz on 1/12 octave centers. The use of 4th order Linkwitz-Riley filters provides steep slopes for a seamless transition between high and low drivers. And with four crossover modes to choose from providing the ultimate in flexibility, all of your system needs are covered:

Crossover Mode (CH1=LPF, CH2=HPF) – When chosen, this mode enables a LowPass Filter on Channel 1 and a HighPass Filter on Channel 2 at the frequency chosen.

LowPass Mode (CH1=LPF, CH2=LPF) – When chosen, this mode enables a LowPass Filter on both Channel 1 and Channel 1 at the frequency chosen.

HighPass Mode (CH1=HPF, CH2=HPF) – When chosen, this mode enables a HighPass Filter on both Channel 1 and Channel 2 at the frequency chosen.

Bridge Mode (LPF or HPF) – When the amplifier is put into Bridge-Mono, you are still able to use the crossover system and employ either a LowPass Filter or HighPass Filter at the frequency chosen."
