Description
Synergistic Research Black Box
First owner, excellent unmarked condition, with original packaging
The black box excels at eliminating room bass nodes and smoothing low-frequency problems without needing power or bulky wall treatments (the box is indeed very small!)
Rarely available on the used market, offered at 50% off the EU retail price.
Local collection welcome & preferred (Monaco / Monte Carlo), delivery possible within the EEA and to the UK (at buyer's cost), but please note that I do NOT accept PayPal (please check my feedback for peace of mind - happy to arrange a video call)
Synergistic Research's product description (from SA's website):
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.
