Well, knock me over with a feather. I have been running my 2000s with a pair of Vandersteen 2Wq subs and M5-HP crossovers for a few years now, and loving it all. But Monday night, my amp messed the bed. So, I had to disconnect the speakers and subs, and run the 2000s directly off the amps in my cheap Pioneer AVR (VSX-1120K), with no subs. Figuring I should skip any serious stereo music listening and stick to background music and films, I put on the EDM channel on FiOS while I checked my email. Wouldn’t you know it! While the bass was not as powerful as with the subs, some of the EDM has really deep synth bass, but the visceral low bass was all there with the 2000s being run full range. It was really clean and well defined, too. Really amazing for a speaker of this size and price, especially with mediocre source gear and compressed audio.  It was good enough to make me look up from my email checking a few times and turn up the volume. I may have to repair or replace my amp, but the Ohms definitely stay!
