I've noticed that stereo amps like the Harman Kardons don't have an option for crossover/speaker size/bass management. How important is this feature when running stereo? Should I get a 7.1 amp for stereo just so I can crossover my speakers to 80hz? I'm using the Ascend CBM-170s.

Some people say that crossing over at the amp reduces distortion because your bookshelves aren't being sent the low frequencies which they aren't made for. They also say that speakers like the ascends are "made" to be crossed over at 80hz.

(I posted this same question in the amplifier forum without much success.)

It doesn't matter which unit does the crossover to accomplish this. There are subs that will also filter the main speaker output.

it also takes the strain off the reciever
a lot of speakers around 150hz and
down the impedance drops to 4 or less
ohms and its easier to let a sub due
what it was meant for to take care of
100hz and down.

There are some stereo receivers out there, such as the new Outlaw, that do have a crossover. I don't really know what the benefits would be either way, but if more subs start going the way of the SVS PB-10 and not offering a built-in crossover, then the crossover on the receiver will be all that more important

Frankly, one reason I like my Paradigm Servo15, v1, is that it has no crossover at all. Only one per system is needed and ideal.
