Is there a pre-amp with a built in cross-over for a sub?

Any home theater pre amp (whether stand alone or built into a reciever) will have outputs for a subwoofer and most will have an electronic (active) crossover with either set or variable crossover frequencies. I am not familiar with ever component on the market but normally if you are purchasing a two channel pre amp the idea is to use an outboard crossover (either active or passive) between the pre amp and power amplifier. Try searching for more information in a good buyer's guide to components.
I have recently purchased the b&k pt3 series II pre-amp.(with remote)
and let me say it is one very cool preamp.
it's a 2 channel preamp (very clean and neutrel) that has a high pass out 80hz on up. full range out. sub out 80hz on down.
it has these outs for both channels so i am very happy as i am utilizing them all and triamping.
very inexpensive preamp , you can pick them up used or new.
there are only 2 things this unit might have that someone would call a fault, is the volume contol is in 2 db increments versus 1 and the bass boost is way to much.(but for the price)
pesonally i don't use the bass boost and the 2db volume control does not bother me.
it was the one for me as i wanted to have a remote! also
I also build speakers and find this unit very useful you can even hook up an equalizer to this unit and a pink noise generator/calibrator if you wish.
