John had a couple of prototypes of the upcoming AV15s and sold me one. Being a prototype, it’s slightly different than the production version will be. According to John, the main difference is that mine has an aluminum sleeve over the pole piece vs a copper sleeve that will be used in the production versions. I’ll let John chime in with the specs if he wants – basically this appears to be a souped up version of the older AV15s.
I snapped a few pics of the driver (which is definitely a beast): http://s117.photobucket.com/albums/o80/jkandreasen/AV15%20Sub/
The parameters on this driver will let it be used in a variety of applications. I’ll be using mine for HT, so I’m putting it in a ported box. I’m planning on about 6cuft, tuned around 20 Hz. Xmax isn’t exceeded until you get up around 1500W!
Once the weather shapes up, I’ll get out in the garage and start making some saw dust and update the pics.
