Anybody Using Room Correction? How goes it?

Tried shakti hollographs, did not like the effect and returned them.

Then I tried 16x48 " ASC tube traps in all four corners.

Huge difference in bass as well as mid and high range imaging.

No more one note bass!

I use the DEQX HDP4. With it (and room treatments) I am able to use full-range speakers and dual subs in a small room with great results. I could get the frequency response to be ruler-flat from 25 Hz to infinity if I wanted, with the DEXQ. Another advantage is that I can tailor the bass output to individual types of recordings or styles of music.
