For a few years, I’ve had a pair in a 3000 cubic ft sound treated room. Their positive impact is on the size of the sound stage — not the SQ. It’s subtle but genuine to me. Best detected by listening with the resonators off vs on. They’re mounted in corners on a horizontal plane projecting several feet above my listening spot. I would purchase them again, but after addressing more pedestrian issues like speaker position.
Any thoughts about the RR-888
My brother sent me a review of this thing in Stereophile. Sounds sort of strange. Anyone have thoughts?
