Never heard it, but it sounds an interesting idea for a studio, not the home.

I was lead to believe that room correction only sounds 'better' in the optimum seating position, whilst the rest of the room sounds 'worse' than normal. Ok, if your on your own, but what if you have friends / girl round etc?

Also, if I had one I'd always be sodding about with the millions of options and not relaxing. This is one reason I want to ditch my sub and get bigger stereo atc's - as I'm always messing with sub positions / dials etc. Each time you add another box, it's just something else to go wrong or need tweeking. I'm sure it will sound different, but not necessarily better. I prefer just listening to music and not tweeking stuff, personally.
