Very rare and MINT condition In-Wall Subwoofer system from BG Radia.
This system consists of FOUR SM-1250 in-wall subwoofer modules (with grilles), and a standalone, rack mountable 2200 Watt BGA-2104 subwoofer amplifier.
The BG Radia system uses a total of 48 small-diameter 4-inch drivers (12 in each woofer module) that are light, fast, and responsive - yet they offer bass extension below 20 Hz. The upshot is a subwoofer that is powerful and goes deep, yet that sounds audibly “faster,” more nuanced, and more transparent than most. Interestingly, BG’s 48 small drivers have the combined radiating area of two conventional 18-inch woofers, so high output is never a problem. Room bass dispersion is even and seamless.

I have rated them as an 8 to comply with guidelines since they have been previously installed. In fact, they have seen very little use and are in very clean, minty condition. These are impossible to find and very rare.
They are, in my opinion, one of the top 2 or 3 designs ever devised to re-create low bass frequencies in the home. They are extremely powerful but are designed to cancel out woofer cabinet vibrations, thus minimizing problems with resonance and vibrations in wall studs and sheet rock panels. Extension down to below 20Hz without discernable wall vibration - and they actually work!
I am looking to get for what I paid for them. Yes they are used but, as they say, find another! :-)
