B&G S12B Bohlender & Graebener Subs

I bought these from a fellow Agoner a couple of weeks ago to see if they would work for a project I was planning.  They won’t work for what I was looking to do.  Just looking to get back what it cost me to get them.  Here is what he had posted:
“First Owner since I bought them new from the factory. As you most will know, BG Radia went under a few years back, so these subs are somewhat rare. They are each a subwoofer "cluster" of 12 speakers in an in wall panel (X 2). In good condition visually and functionally. Note that they have been painted from the factory white to a mellow tan color to match the surrounding walls, as noted in the pictures. Works perfectly. Used to supplement my mains for Saturday Night movie night, not for anything else as my main speakers are full range. Not a lot of use as a result.  No original boxes, but will be packaged well for the ride. I have two of these modules I pulled from my theater, price is for both. Shipping is on the buyer; I will pick up the PayPal fee.  
Manual can be downloaded, as I did:
