Bohlender Graebener BG Radia 500wpc subwoofer amp with crossover for BG's $12,000 Line array speakers (or any ultra audiophile subs that need a true high end amp!)
Class AB Amplifier with BASH technology. 8 ohm rated, stable to 2ohm, rated closer to 800wpc @ 4 ohm - Very hard to find, high end subwoofer 2ch amp.

Designed to work with BG's flagship 92db sensitivity, ultra-audio R-800 (USD $12,000 avg price) 8' tall line array speakers, the BGA-2500 subwoofer amp gives unlimited power to any passive set of quality subs with fast, deep and musical bass. This amp also does an equally impressive job in a high end bi-amp setup with this amp running the bass portion of the speakers. The internal sub crossover is extremely accurate. This was its intended design with the R-800's, since they were a bi-amp configuration.

I am the 1st owner of this unit, I received it with my pair of BG R-800's in 2013. I have since had my R-800's upgraded to LA-800's (which now use an internal 3rd order passive xover), running off two Theta Promethius amps, and as such I have no longer needed this specific amp. I did use it for a time to run two passive 18" Bag End infrasubs and it worked fantastic. My new Bag End subs are self amplified so I figure it is time to see if someone else might enjoy this fantastic sub amp.

MSRP for this amp by itself was about $1500. I'm asking $700 with free ship to 48 States USA. Works perfectly. Front face is immaculate. Top of case has some light scratches from install in a typical audio rack. ** Note that this amp has been upgraded by BG Radia in 2014 for cleaner audio resolution. As such the audio-detect auto turn on no longer functions (the internal circuits are bypassed). So you will just leave the function switch in the "on" position. The auto turn on circuit injects some slight harmonic distortion into the audio line hence the upgrade and modification by BG. None of your true audiophile amps will have audio detect auto turn on.

Money order, local pickup w / cash, or PayPal ok. PayPal please add 3% - FREE USA insured UPS or Fedex shipping to 48 States - AK / HI I will ship but there will be an added cost. Please ask me for a total before paying (about 22lbs boxed and 18" x 18" x 10") . Local pickup in West LA / Beverly Hills is fine.
