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. So when you get the phase correct at 20Hz for example, it clears up every multiple of 20Hz so, 40Hz, 80Hz, 160Hz and on.
Price of $995.00 is for each BLACK BOX.  That is 50% OFF!

I have 2 BLACK BOXES without Logos (my preference), and 2 BLACK BOXES with Logos.  Please pardon the dust in the photos.  The units were dusted before boxing.
My experience was that placing the BLACK BOXES to either side of the front speakers, with 2 units was far better than any other placement in my room.  I also stacked the two other BB on top of the first 2 for even greater effect over the broad range of frequencies.  2 BB stacked to the left of the left speaker; and 2 BB stacked to the right of the right speaker...

"...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..

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..

I am selling my 4 BLACK BOXES.  i have changed to Duevel Jupiter speakers, that have the bass firing UP, and a 360 degree pattern.  Which create a completely different bass and sound dispersion challenges than forward firing speakers.
