The Acoustic Revive RHR-21 Acoustic Resolution Exciter has received several awards, including the Mono&Stereo magazine’s BEST OF 2023, MJ Technology of the Year Accessories Category Excellence Award, and Audio Accessories Grand Prix.

Despite its small size, it effectively cancels standing waves, surpassing larger room tuning systems. Thanks to a special structure covered by a utility model patent, it achieves a standing wave elimination effect that exceeds that of larger room tuning products. It can be placed in the corner of a room, near a speaker, behind an audio rack, or any location where standing waves tend to accumulate, providing clear and high-quality sound.

Dramatically improves the resolution and phase characteristics of audio playback!

The RHR-1 can eliminate standing waves and unwanted reflections, along with fixing frequency band bias in the listening room. This results in a significant improvement in audio playback and phase characteristics. Additionally, instrument and voice timbre and texture are notably enhanced due to the absence of frequency peaks or dips. It brings about a three-dimensional, clear sound image positioning, and extensive sound field reproduction, surpassing the capabilities of simply upgrading amplifiers and speakers.
