You guys may have a laugh at this, but in my 2-channel reference room I'm using the Dunlavy SC-Vs with a Dunlavy subwoofer. Only a few of the subs were made and this one is in an SC-IV cabinet with 4 twelve inch woofers. It's passive so I use a separate amp/equalizer with it. The result, well if you love your bass clean and able to slam you through the floor, this set-up gets it done.
Also, I agree with the recommendations for tube amps. I've tried different amps, but personally I have liked the high current stuff from Jeff Rowland and the Marantz Reference Monos the best.
