Acoustic System Intl. Resonator -Basic or silver (demo unit)

These are the Acoustic System International Resonator devices. How these little cups can improve the sound of an entire room doesn't make sense, but they work wonders.

From 6Moons:

"The change was very obvious. Besides increasing stage depth, bass was much tighter and coupled better to the room. After a few CDs, we additionally concluded that not only was image height more defined but it had in fact increased."

"They're the most eye-friendly effective room treatments we've come across yet and highly recommended."

From Positive Feedback:

"Yes, they add gobs of body and make the sound round, softening sharp treble edges in transients. The resulting sound is less mechanical and more acoustic. But, unexpectedly, the Resonators' major impact is improved dimensionality and imaging."

We also have a used Silver model, but you want to start with the Basic model, regardless of how many others you will use. The Basic is the starting point to fix your bass; place it at the base of your floor, between your speakers. Listen for several nights, then take it away...you're going to want to put it back.

Pricing:

Basic (Copper) - $225
Silver - $475
