It's a decent performer, but doesn't stand out in any way. My first pick for desktop duty that's around the $300-400 range is the Mordaunt-Short Aviano 7 sub.
Usually when place with desktops, positioning isn't idea, usually it's sort of boxed in and creates unwanted resonances and reverb which leads to more of a boomy, one-note-wonder sort of sound. What's nice about the Aviano is that it has a variable notch filter built in which allows you to take a narrow frequency range and reduce the output, this allows you mostly get rid of that 2-4 note region that gets amplified out of control.
Unfortunately, I'm not sure what's happening with the availability of it. It's still listed on their website, but none of the distributors seem to have any stock. If you want to take the time and try track one down, I think it'd be worth the effort. It's a solid performer on it's own, but with access to the filter it makes a great choice it the desktop environment.
Otherwise my next choice in the under $400 range, would be the NXG NX-BAS-500 which is actually cheaper at $270. I choose this because it's a relatively flat and more accurate sub compared to others up to the $400 range. Here's a review which seems to sum up the consensus of what this sub is about.

Otherwise as I said, the BIC is a middle of the road sub, doesn't really out perform others in it's price range, but doesn't really lag behind them either.
If you are willing to up the budget to around $500, a whole different world opens up at that point.
