proggy, I didn't mention this in the other thread, but the 20-39 is BIG. You really won't appreciate that until you uncrate it. Even as big as it is, it just blends into the background after a bit. The listening/feeling experience will get anyone over the hump. As an aside, I have mine semi-hidden behind a chair. No downside on it's performance sitting there.

I'll make the assumption that an SPL meter and Avia disk are somewhere in your future plans. Once you get the calibration done, give yourself a treat and play the sub sweep tone. It is amazing going from listening to feeling. At 20hz, there is lotsa feeling to be experienced!
