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. For a subwoofer that was almost 800$ new after taxes... you expect it to last more than 18 months.
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. Set up right they blend toghether well and sound great. I recommend this sub for a similar set up to mine. This sub would work for a larger speaker system but I would go for a 10" or 12" sub.
Summary: This sealed subwoofer is an excellent for those whom are looking for the punch oppose to the boom. I have several of these subs in my home. They are all utilized in smaller rooms - 12X15. They work great for the punch of music, home theater I feel is better suited for a ported sub. They main speakers in all rooms are the icon series which work great with this sub. Would I buy this sub again, yes - I like the punch!
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. It punches hard, but remained tight into the lowest of the lows, without resorting to that echo-y "trunk vibrating" bass that so many of us hear in cars.
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. What I was searching for is sound quality above power, and it is what I've got. In addition, this subwoofer has a digital processor and some config options available on the subwoofer itself.
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). I hooked it up to my Pioneer Elite SC-05 receiver, without calibration, and began to watch the desert battle scene in Transformers 2 and it sounded muddy and boomy.
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. I'm going to take this as just another omen that I should never again buy Klipsch products, as much as I want to, and will likely stick with Def Tech or another brand like HSU.
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. I bought this subwoofer when everyone on line had it for $699. I went to Best Buy and got it for $499. One of the semi-rare times that BB could beat Amazon.
