Here is a video describing the HST-11 with a demo of its excursion. You will not get more displacement for a smaller cone- 38 mm xmax! Given its capabilities, it is actually very cheaply priced. If I had to have a small sub, it is what I would go for. You could get one, an iNuke 3000DSP, and everything else you need for the subwoofer build for less than the cost of a minivee. Needless to say, that would smoke a Minivee.
