Pros: Sounds great and can be adjusted to your preference with controls on the back of the speaker ... so if you like rattling your windows or just a subtle base I would highly recommend this subwoofer.

Cons: No cons at all

Pros: Great sub for the price. Great performance by Klipsch.

The sub produces tight solid bass that adds incredible dimension to your sound stage. I set it up with a pair of polk monitor 60s, together - ear candy. I've used it mostly for music and its great (i'm yet to watch a movie with great soundtracks since i got it) I like its size - not huge yet big enough construction to ensure performance. The lows are not boomy but tight and hard - like they should be IMO.

Update: Watched some movies and... Incredible! It's so great my little guy was scared of the sound of a falling tree; he run - literally. And this in a room that is far from anything close to favorable for great acoustics

Cons: Non so far.

Pros: I just received this unit from Newegg and swapped it out with my good old 12 inch 250 watt sub and I was truly impressed! My old sub sounds a bit punchy and boomy but this 10" was awesome. Good bass. Adds great presence in the low end and simply sounds great.

Cons: I cannot think of any cons at all. It works, sounds great and looks good.

Other Thoughts: I would recommend this my friends and family too.

Pros: Nice deep sounds for the cost. 12's drive lower but if paired with some decent full range main speakers this provides all the low end rumble you need for TV/movies.

Cons: No Cons found 1 week in.

Pros: It works great with my Yamaha receiver. Great subwoofer and other speakers. We finally have some great sound while watching movie.

Cons: The subwoofer itself is big and heavey. But it is not bothering me.

Pros: The price is awesome for the performance of this Sub. The sound is good. Complements the Klipsch minuet SL speakers I paired this with.

Cons: None so far.

Other Thoughts: I purchased this sub for my bedroom. It has decent sound quality for the price range. it compliments my other speaker without being punchy or feeling like it's going to vibrate you out of bed, yet can let you hear and feel the deeper sounds from movies.

Pros: Deep bass great for movies and music. Paired this sub to Klipsch KF-28 Floorstanding and the results are far higher than expected the bass is tight and punchy or low when needed. Very high quality front firing sub!

Cons: None

Pros: Quality sub that provided sweet, impressive exacting low end sound reproduction that enhances surround sound and music without the excessive, harsh and boomy unrealistic sounds so often heard from many other subs.
Provides very good/accurate low end sound reproduction with power to spare.
Provides the feel of great low end sound reproduction.
Wonderful with with movie playback or music.
For it's size and being placed on carpet, it has very impressive low-frequency response for movies and television. Crossover provides a clean cutoff.
It easily can be blended with any speaker set.

Cons: None.
This sub is great plus I only paid $130.00 for it through Newegg.
Compared to the highly reviewed and rated Polk PSW10, well there just isn't any comparison as the Klipsch K100-sw reference sub just blows it away.
This sub compares far better to much more expensive quality subs.

Other Thoughts: I am very pleased with this item and without question would purchase this sub again.
