Tune your acoustics.

About the size of a shirt button, yet powerful enough to transform the way you experience music, HFT’s improve nearly all aspects of system and room performance. With HFT’s your speakers and room disappear leaving you with nothing but a live holographic musical event in your listening room, or living room. HFTs oscillate at high frequencies creating an energy field in your room that overpowers room vibrational distortions to correct phase and frequency interactions for harmonic balance in your treated room. You hear an increase in depth and width, with clearer more extended highs, and tighter bass. Everything sounds more live, clearer, and more natural than you could ever imagine.







HFT X's are added to your existing HFT installation to add focus, resolution and air. A combination of standard HFTs, HFT 2.0 and HFT X will provide the most balanced results.



 the overall results were quite startling. When my wife walked into the listening room after the process was finally completed, she made one of those quick jaw dropping expressions and sat down without a word. Nothing more was said. She just wanted to listen to the music without interruption. I understood.

Images truly stabilized and were much more clearly defined—even on the most mediocre of recordings. There was considerably more air and immediacy around individual instruments and vocalists. The soundstage extended well beyond the outer edges of both speakers and seemed to reach beyond the front wall and all the way back into the listening position.
