Any of these speakers are an overkill for computer speakers. They are designed for home theater use in a large room. It's like getting a V8 Mustang for delivering pizzas: you could do it, and it would be fun, but it just isn't a good fit.
The MW-15, as someone else has already mentioned is a MONSTROUS subwoofer. Most people do not pack something this serious in their "home theater", let alone computer speakers. It will shake your desk, rattle your air vents, and make your pant legs flap. This class of subwoofers delivers a level of infrasonic performance that brings tactile sensation to a movie watching experience. Normally, you have to spend $800 to $1k for a subwoofer of this class, but MW-15 was designed to be a high value subwoofer to begin with and, well, the owner of AV123 was indicted on charity fraud and the shop is close to folding. These remaining MW-15s are likely returns from the first batch that suffered from premature amp failures: their amps were probably replaced with updated amp designs that corrected the issue. I recommend the MW-15 to anyone looking for a serious subwoofer because the current price is just unbelievably low. Down side is that the company is not likely to be around much longer and the wife-acceptance-factor isn't that great given the size of this thing. Maybe you can disguize it as an end table or something.
HSU is nice, but as of late they've been running off in a head-scratching direction with their subwoofer designs. And none of their lower priced selections are anything special compared to internet-direct offerings.
Everything else: Velodyne, Polk, REL, etc, are great for people who are loyal to those brands but they offer very little in terms of performance against the likes of SVS, HSU, Epik, and ED.
