SteinMusic Acoustic Discs

We've been using acoustic treatments of one kind or another for years — absorbers, diffusers, dedicated panels, various active and passive devices from manufacturers who understand that the room is half the system. The SteinMusic Acoustic Discs are the best of any of them we've tried. That's not a qualified statement.

The walls disappear. The soundstage opens up in width and depth simultaneously. Instruments and voices gain presence and three-dimensionality that wasn't there before. The effect is immediate and doesn't require extended listening to notice.

What They Are

Two-inch diameter discs that place on any room surface — walls, windows, ceiling, behind equipment. They use Holger Stein's proprietary treatment technology, which he consistently describes as quantum physics — not a casual use of that phrase but a reference to a specific design methodology that runs through every SteinMusic product. The discs work without power, without any active component, without any audible mechanism that a conventional engineer would recognize.

Placement

First reflection points are the obvious starting place — the wall surfaces that your speakers' sound reaches before it reaches your listening position. The ceiling between the speakers and the listening chair. Behind the listening chair on the rear wall. Experiment. The discs can be repositioned and the effect changes with placement.

Press Recognition

SteinMusic Acoustic Discs have been reviewed by The Absolute Sound and Positive Feedback, with consistent reports of dramatic improvement in soundstage size and image stability. Some reviewers have called them the most effective room treatment they've encountered in any form factor.
