Synergistic Research Acoustic ART analogue room tr

take a look at the treatment size, The bowls are smaller then a shot glass. I would guess that they are to small to even make a difference in a broom closet not alone a fair size listening room. The price of this room treatment is a staggering $3000.00 mark without providing measurment's.I believe room treatment must be thick and large to make a considerable difference in one's listening room.

I'd like to take a stab at whoever is responsible for this nonsense! The Greeks and Romans used "sounding vessles" in their open-air theaters to produce reverberation, not a desireable trait for audio listening.

A dealer demoed similar things in my room before. The whole set was about $4k to $5k. Yes, it made some diffences. Was it worth it? No. I just can't see myself spending $5k for some tiny little thingy.
