Thanks, I was thinking about trying Eighth Nerve if I went the pillow route. Mejames, would you care to describe a little bit how you went about tuning your PZC's-- what was the basic method as you went around and tuned the various pieces (looks like you have a mini echo controller on the front top seam as well as the corner controllers) and what you heard change as you arrived at your current setup? I'd be interested in getting a better feel for how one uses these devices.
Corner treatment -- PZCs a sure thing?
I'm looking for a set of room upper corner treatments for my living room. The upper corners probably are the only places in that space where I can use audio-specific treatments. The triangular pillow-type traps seem like a pretty sure thing; it sounds like only good can come from reducing the amount of energy being megaphoned out of those corners. I'm not so sure about the tunable pressure-zone controller devices (Michael Green). Are they as versatile and sure to be helpful as the pillow traps? Can anyone describe the comparative effects of these two approaches in their room and system?
