Synergistic Research Black Box with spikes, papers and original box and packing. Please see all pics to help description and condition of this Black Box for sale.

Please note: we are an Authorized Synergistic Research Dealer and this Black Box Trade-In came from one of our best customers who is a very serious audiophile who travels to all the audio shows, does many auditions and knows his audio gear and is very meticulous about his gear. Will be shipped to you with the original box that it came with, inside a protective outside shipping box. We're listing as 7/10 due to some small white specs on the black mesh grill that is visible in pics and could be removable. This is your opportunity to try SR's Back Box at a great price.

Deep space meet deep bass.

There is no other compact acoustic treatment device that you can place in your listening room to solve your low-frequency problems except the Synergistic Research Black Box. Based on our 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 spacial 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.


Even if you don’t have a bass problem in your listening room you can benefit from the Black Box. With improved low-frequency definition in perfect phase alignment with all frequencies that make up your favorite music, you hear natural sounding bass in a holographic soundstage with mid's and high's that sound natural and transparent. And unlike large bass traps, the Black Box performs this feat in a small, aesthetically pleasing package. The Black Box sits on three stiletto spikes decoupling it from your floor for improved response. Black Box measures only 9.5″L X 9.5″W X 6″H (8″ when spiked) and weighs about 8 lbs.
