Similar to what price?
If you go to the subwoofer section of this forum there's a thread (many, actually) about effective budget subwoofers. I have a BIC Formula F12 that I picked up off the local Craigslist (in perfect condition) for $120. There are plenty of good options out there, I don't know what your budget is. What I do know is almost anything recommended in those threads will outperform the one you listed, and that makes more difference in home theater than most any speaker or receiver.
