I tried the BB for three months (mostly in the box). I use 32 SR HFTs and tried the BB with and without the Atmosphere XL4.

The BB made the sound more warm in the low end; but; unfortunately, it cut off the highs at about 8Khz. The highs just vanished. This was seconded by several friends and a cable manufacturer. Just lopped off the highs. Very dissapointing as my dealer said only 10% are returned.  I placed it behind, in-line, in front, on the sides several locations, on the rear wall, all over.  It's effects were most prominent in front the speakers and in the middle of the room.  

The SR HFTs replaced a slew of absorption panels and nearly eliminated slap echo in a too reverberant room. I will be using them in my new home’s custom $165,000 listening room. The designer said that I could gain 100% more spacious sound with a quad diffusers at $30,000. I’m going to try my SR HFTs instead plus I don’t have the extra funds, don’t want two walls with 17" deep diffusers if I can help it.
