HFT

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.

The original HFT's will make up the bulk of your HFT acoustic treatment. Most rooms are recommend to start with 15-20 standard HFT's. Your speakers and room will disappear as your soundstage expands into a realistic and holographic representation of the musical event with improved frequency response from top to bottom.

 

 

HFT

Room Treatment Placement Guide

Easy as 1, 2, 3

Step 1: Start with Standard HFTs

Level 1

Center mid-height between speakers
Left front corner—mid-height
2+ feet above left corner front
Right front corner—mid-height
2+ feet above right corner front

Level 2

Front wall center low height between speakers	Right side wall mid-height 1/2 distance between speakers and listening position	Left side wall mid-height 1/2 distance between speakers and listening position
Ceiling center 1/2 distance between speakers and listening position	Rear wall center 6+ feet height

 

Level 3

Left side wall mid-height behind listening position	Front wall mid-height between center HFT and right speaker Front wall mid-height between center HFT and left speaker
Right side wall mid-height behind listening position	Rear wall low center

 

 

Step 2: Add HFT 2.0s for warmth

Level 1

Place HFTs on both sides of each speaker, adjust downward for warmth
Replace existing center low and place midway between top HFTs

 

Level 2

Replace existing left and right HFTs and move toward ceiling	Replace existing right HFT and move toward ceiling
Replace existing left HFT and move toward ceiling	Replace existing center mid HFT and move toward ceiling

 

Step 3: Add HFT Xs for clarity and focus

Level 1

Replace existing center HFT and move toward ceiling

 

Level 2

Place 1 HFT X on top of each speaker

Place HFT X below other HFTs on back wall, rearrange for preference

 

 

Step 4: Add HFT Wide Angles for width and scale

HFT Wide Angle’s are added sparingly to a room already treated with HFT’s. With a wider and more powerful dispersion pattern, they dramatically increase your sense of immersion in the sound field while expanding the scale and dimension of your soundstage.

 

Level 1

Damped rooms - Place HFT X Wide Angle on your front wall, centered between the speakers at about ear level. Moderately damped rooms - Place HFT Wide Angle on your front wall, centered between the speakers at about ear level. Lively rooms - Not recommended.  See Level Two guide below for additional placment.

Damped, moderately damped rooms and lively rooms -Place HFT Wide Angle on the left wall, near listening position at about ear level.

Damped, moderately damped rooms and lively rooms -Place HFT Wide Angle on the right wall, near listening position at about ear level.

 

Level 2

Damped and moderately damped rooms - Place HFT Wide Angle on each side wall behind the main speakers when speakers are pulled a fair about of the way into the listening room -or- on side walls between the listening position and the main speakers. Lively Rooms - Not recommended

Damped and moderately damped rooms - Place HFT Wide Angle on each side wall behind the main speakers when speakers are pulled a fair about of the way into the listening room -or- on side walls between the listening position and the main speakers. Lively Rooms - Not recommended

Damped, moderately damped and lively rooms - Place the 3rd HFT wide angle on the rear wall behind the listening position. Test vertical height for balance (higher and lower placement from ear level will provide more warmth).

Synergistic Research High Frequency Transducers - HFT Standard, HFT 2.0, HFT X, and HFT Wide Angle - Read More

"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." - Robert Youman

"The HFT/FEQ combination serves to make your listening room canvas more pristine so that when your audio system paints the music on it, the end result is a lot more true to life. Needless to say, the Synergistic Research HFT/FEQ combination I used in this review is not going anywhere. They are now an integral part of my reference audio system." - Malcolm J. Gomes

"The effect on our system was immediately obvious:  A thin layer of hash that had been below my notice (Ain't it always the way?) was removed, clarifying a system that I already thought was exceptional.." - David W. Robinson
