Synergistic Research Black Box high end Acoustic Treatment Device NEW

New with high discount! One Synergistic Research Black Box high end Acoustic Treatment Device in black color. 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 award-winning and patented sympathetic resonance technology, 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, 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 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 sound stage with mid's and high's that sound natural and transparent. And unlike large bass traps, Black Box performs this feature in a small, aesthetically pleasing package. Retail price is 1.995 euro, now for 1.649 USD only! The original box, manual and stiletto spikes are included. Check our other listings for more interesting items. Free shipping worldwide!
