If budget is in your mind...those subs might fit the bill for the time being, but dollar for dollar, the HSU STF-2 and the SVS PB10 are the absolute best for the money. They can be had for a little over $400. The sub is an integral part of a home theater setup. I'm pretty confident if you were to listen to any movie at decent levels, those subs you were considering would start pooping out and getting overdriven.
Actually, I'd highly recommend the system I have. The whole thing, speakers, sub, receiver, and cables came to around $1900. It is truly amazing. It's in my signature below. The receiver was a Yamaha RX-V557. The Yamaha's are a bit more respected than the Pioneers in the audio world. I first thought a pioneer would be the best choice, but for the price, and after looking at many reviews, the Yamaha RX-V557 is an excellent budget choice.
