Martin Colloms review of the Harmonix Discs - Stereophile August 1993.
"In contrast to other room-acoustic control systems, no sound absorbing action is claimed for these devices. Combak intends the discs to be attached to major room surfaces, particularly the ceiling etc.
Despite my former positive experience with Combak tuning devices, I was skeptical that these discs could improve my listening room, which is known to have good, well-balanced acoustics. Evaluating component or loudspeaker improvements is my field of expertise.
The Harmonix Room Tuning Devices were fascinating in that they had zero effect on the primary room acoustics, the room's low-frequency model resonances, or the early reverberation pattern. Yet something WAS significantly different. The room seemed to allow a wider dynamic range, sounding strangely "quieter" and allowing for darker, deeper silences between musical notes. The decay structure of individual notes was cleaner and clearer, while, in many cases, the definition of note values was substantially improved.
Freeing the end points of notes from a previously unsuspected straight-jacket of blurring, muddle and obfuscation. Moreover, stereo focus and image uniformity were surprisingly improved. Some stereo image distortion that I had assumed to be due to reflections from local boundaries was lifted away.
Singing voice became more natural and articulate, with a surprising improvement in intimacy and presence. Complex material was definitely clearer, while massed choir showed better definition and clarity with less hardness and "clogging up". Even more remarkably, the music's dynamics, rhythm, and timing were significantly improved, to the extent that I just sat back and ignored the details, the subjective analysis and the attempt to describe how it works. You just relax and enjoy the greater swing in the music, the flow, the clarity, the easy dynamics and the control.
Another fascinating aspect is that the room tuning device treatment not only makes the Hi Fi sound better, it also improves the sound of the radio, TV, piano."
