Well, in my search for what driver I want to use in my DIY sub cube, I think I may have found it. It looks to have alot of the specs of the HE15 from stryke, with about half the cost. If indeed it would be good for my sealed or vented cube, I'm totally sold on buying one. Anyone else have ideas? check out their news site for detail, says 1803 coming in a few weeks.
