active room nuetralizer???

I use the Bybee Room Neutralizers (non-powered) in my room- a set of 8 does the job nicely.  The DO make the room boundaries disappear sonically, but are not going to fix nulls, peaks, and other issues.  These need to be addressed first and then when the sound quality in the room is relatively even, the Room Neutralizers will take it the rest of the way.  Good Luck!

There’s a bunch of active and passive room "neutralizers" including but not limited to SteinMusic Harmonizer, tiny little bowl resonators of various manufacture, Lessloss Blackbody, 1 GHz Ultra Tweeters, Sugar Cubes from the tiny little bowl guy, Marigo VTS Dots for walls and windows, tiny crystals for room walls from Acoustic Revive, Schumann Frequency Generators of various manufacture primarily Acoustic Revive and Mpingo disc.

...and just to add to the mix of things one can do, I ran into this tidbit.  Since I like to 'run the room' eq'd for flat response as much as practical, this seemed a tempting approach...

Enlist the room in fixing itself.  A simplification, sure, but interesting.  Might minimize the amount of 'stuff' needed to tame the space.

Just a suggestion...

...appealed to me as it would seem to be an easyish thing to DIY....I have a lot of other things I'd drop 3K$ on these days...
