Winner of StereoTimes’ Most Wanted Component 2015 Award and the Positive Feedback Brutus Award 2015. Now also available in white finish.

From the mind of Synergistic Research’s lead designer Ted Denney comes the Black Box. In development for over two years, the Black Box is now perfected and ready to transform your listening room.

Check out the latest review on Audio Bacon - CLICK HERE to read it.

Based on SR's award-winning and patented sympathetic resonance technology, the Black Box is an (all in one) Broad Spectrum Low-Frequency Resonator Array with UEF Tech that effectively eliminates bass nodes while expanding your room’s ability to accurately portray low-frequency information and spatial content. Working from the principle that all frequencies in the audible bandwidth are linked through harmonics, the Black Box balances low frequencies, mid-range, and high frequencies through a mathematically derived algorithm based on tuned sympathetic resonance. So when you get the phase correct at 20Hz for example, it clears up every multiple of 20Hz so, 40Hz, 80Hz, 160Hz and on.

Customer feedback:

"...while I didn’t have a really BIG problem with unruly bass overload in my room, it was bothersome enough for me to want to seek out some kind of remedy. Since I’ve grown quite accustomed to the positive results of having other Synergistic Research products in my system, (thanks to Alfred),I though why not try the Black Box. Not only did it effectively tame the noticeable boominess, but I realized how much clearer the rest of the frequency range had become. The mid range opened up and oh how sweeter the highs had become! This device is way more than it pretends to be, and works very well at making music so much enjoyable. Thanks SR... keep up the great work!"

"...the black box is a revelation helping to open up the whole dynamic range which enables the music to sound so clear and relaxed. Another great product from SR!"

"...thank you Alfred for recommending the black box. awesome device, indispensable..."

Mike Girardi, The StereoTimes, January 2016, wrote:
"...there is no other room acoustic enhancement device that I know of that can transform your listening room in the way that the SR Black Box can deliver. Once you hear The Black Box and how it can affect the music and the listener, you’ll be hard pressed to take it out of your system..."

"...with The Black Box in my system, the bass response was clearly better in all ways but the magic really occurred in the midrange and high frequencies. The improvement in soundstage was undeniable with each recording displaying a greater sense of depth … the music sounded liberated in a way while percussion instruments displayed a faster transient response. ’Synergistic’ is one word I would use to describe the combination of SR HFTs, Atmosphere, FEQ and Black Box working together in my listening room to eliminate the negative impact of my listening room. The Black Box is a must have component if you really want to hear your system at its full potential..." CHECK OUT the entire review.

Dr. David W. Robinson, Editor-in-Chief, PFO, November 2015:
"...when the Black Box was added, well, damn me ears! The bass did seem to lock in, becoming more precise and more focused, all at the same time. We confirmed this by having Peter move the Black Box out (Rats! Bass improvement lost!) and back in again (Yes!). There was no doubt about the gains that the Black Box offered…that bloody thing had to stay..." CHECK OUT the entire review.
