Ask Engadget HD: What's the best home theater subwoofer under $500?

So, you're one of those "build your own multi-channel surround system" folks, are you? If so, we'll bet you're a lot like Jeff (and you didn't even know it).

"I'm in the process of assembling a 5.1 system for my den, but I'm really concerned about making the right decision on a subwoofer. I'm putting a cap of $500 on it, but I want the most boom (and tightest boom) for my buck. I haven't purchased my towers or surrounds yet, so I'm open to any brand / model / etc."

Ah, starting with the low-end, are we? Probably not a bad place to begin, quite honestly, and we're hoping that you readers can chime in with a few recommendations for this here bass lover. Rumble away in comments below.
