Long time member. Haven't been around or posted in ages. Good to be back ... I have a question about a Velodyne F-1200-B (Foundation Series) Subwoofer that I recently acquired ... mainly if anyone knows the specs of it as I can't find any online. Also what is the difference between the Foundation Series and the same model number but Servo Series? Looking to sell it actually but would like some info that I can list it along with. Thanks much for your help!
