Summary: As musical and poised as you can get at this price point even all these years after its release. Do your homework and read the reviews, this is a gem of a little sub that isn't the least bit boomy or obnoxious. Adds a nice tight bottom end on music as well. Awesom controls and settings as well.
Summary: I purchased the Klipsch XW-300D subwoofer along with a whole theater room 7.1 surround system of klipsch icon speakers 18 months ago. They sounded FANTASTIC in my house... up until this last weekend. The subwoofer gave a few vibrating buzzes during some music and then cut out all together.
Summary: This sub sounds great with the right system. I paired this sub with the Klipsch Quintet 5's. These are satelite speakers which are great but they can't produce the mids/lows that big speakers can. This sub really picks up where the quintets leave off.
Summary: This is one heck of a sub. It looks great, and is a small sleek design that tucks away nicely into a corner, or in my case underneath a table. This is great, because it's less a piece of furniture and more a sound producing device. Once I hooked it up, I was right away blown away by the power.
Summary: Great sounding, compact sub! Easy to use and install. I haven't even calibrated my system yet, but it is even better than I thought it would be. I'm not into the wall-shattering bass, so this is the tight, low and clean bass I like.
Summary: As I'll take this subwoofer abroad (I don't live in USA), size was an important factor in buying choices. I've searched for some other options like Polk PSW-111, Polk DSW MicroPro 1000/2000, Mirage MM-6 / MM-8, and others.
Proof that there is no replacement for displacement

Summary: The bottom line is that this subwoofer, while small and capable, doesn't hit hard enough. It also is not for the plug-and-play set. I bought this subwoofer to replace a 10 year old 10" ported 150 watt Pioneer subwoofer that quit on me (it did have a decent BASH amp in it).
Summary: ...if it didn't fail the very day BB was about to sell me their floor model at a discount. This comes as little surprise to me, though, as I've experienced a history of short-lived Klipsch subwoofers, of the 5.1 Pro Media kind.
Summary: I bought this subwoofer to go with my new Klipsch icon x series center channel and sattelite speakers. This subwoofer is totally awesome. Read the expert reviews online and read the customer reviews on other Klipsch speakers sold on Amazon, like the Quintets for example.
