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.
Why 3 Spikes?
When attempting to achieve a perfect base for isolation, 4 points seems like the most stable option. But what soon becomes clear, is that unless you have a perfectly flat surface, your points of contact will always have 1 foot not touching. 3 points of contact creates a guarenteed base, removing the chance for a loss in isolation. Sharp points poke through carpet and fabrics to hit the floor beneath.
“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.”
"It is therefore no surprise that I give the Synergistic Research line of products covered in this review my very highest recommendation…enthusiastically! This is the real deal, amigos!"
"After our initial testing of placement, an insanely easy A/B test. We listened with the box resting near the edge of our rug, put the box outside into the patio, listened again, and put it back in after listening. While the Black Box seems like it’s advertised as a bass tuning and improvement device — it’s more than that. It seems to build upon what the HFTs were doing and takes it up another notch."
