I am waiting for the Emotiva USP-1 to come back in stock (and possibly go on sale

). If you want to try separates, it has a sub-out with adjustable crossover. Of course, you would have to buy a separate amp (I'm using a UPA-2.)
The HK3490 has a sub-out. It sends a full range signal to the sub, so you would have to use the sub's crossover to limit it. I have one of the previous 3480's in a bedroom set and I have been very happy with the sound quality. The remote is a cheap piece of junk.
