The Velodyne SPL-800R isn't the smallest or newest Velodyne subwoofer, but it caught my eye since I'm in a hunt for small, manageable, high quality subs-as you might gather from a few of my entries hereabouts. It uses a 10" driver, is a bit over a foot all around, and will run you $$1249. The larger SPL-1000R to its left can be yours for for $$1649.
