I picked up one of the demo models from Cointaker at Pintastic. I agree with a previous poster in that there is not a lot of bass from those speakers. Sound clarity is there, and the amp they used is capable. It is the same amp that is in Rob Zombie, and that pin kicks. I can't do an external sub (house rules, nothing under the pins), so I am trying to come up with another (internal) solution. I could install my own cab sub, but I don't really want to drill through the botton of the cabinet....I need to think about this more....while I play this AWESOME pin.
