It seems these days that everybody and his brother is doing something about room equalization. Sure, we had the old-time graphic and parametric EQs—now we're seeing much more sophisticated and dedicated devices, from the TacT
standalone products to the auto-setup and EQ systems found in many A/V receivers. I was impressed with the Audyssey MultEQxt in the Denon AV-4806 receiver—see my "Music in the Round
" column in March, p.50—and a standalone AudysseyPro unit was demonstrated at the 2006 Consumer Electronics Show.
