2-Pack R-100SW 10" Subwoofer, Incredibly Deep Bass and an All-Digital Amplifier,14 5" x 12 5" x 16 4"

These subwoofers do the job. I used to have the 12 inch version and they would rattle the house. They can also but they are a little smaller and take up less space in the living room. I am very happy with these they are more than enough for a 5.2 or 7.2 surround sound system.

I've had my Klipsch floor standing speakers since 1994. Still pumping clean, loud music, never had a problem. But, hey. Who doesn't like a little more bass?! I ordered the 2 pack of R-100 SW's and gave one to my son. We both love them. Not muddy. Not boomy. The built in amp is more than sufficient for our application. (Medium sized room.) For a larger room I would be thinking about a larger diameter driver (12", 14"), which would also pump more watts. Music and Television really came to life. A powered sub, such as this, takes the low frequencies away from the tower speakers, freeing them up to really sing the mids and higher ranges. My kid has this sub paired up with Klipsch R51- PM powered bookshelf speakers for an affordable, clean looking, and compact bedroom system. Synopsis: We both love this Sub. Would buy again.

Excellent quality

I needed subwoofer to go with my satellite Bose speakers from the Accoustanass 10 without the Control module which was the subwoofer.

I replaced a single 15" sub with two of these Klipsch 10". I was dissatisfied with the lopsided bass sound located by the left bookshelf speaker. I couldn't place it in the center in front of the large shelf system holding the tv and stereo equipment. I am more than happy with the results and the quality of these Klipsch subs. I was going to order the 12" subs but wanted to keep the size to a minimum since they sit next to each bookshelf speaker. I'm so glad I went with the 10". The bass is more than I expected and the improvement in the sound stage is amazing. Delivery was very quick, and the 10" subs are lighter for me to carry than the 15".

Great low frequency sound and will shake the house when watching movies

While these aren't the best for movie explosiyes they do okay. They're best at music reproduction. The downside to these is that the case tends to vibrate too much during very low tones. To combat this and get a cleaner sound I put a sandbag on top of the case and it helped a lot to produce a cleaner base sound.

I have used these on several entry-level Home Theater Installations, they are a good budget subwoofer.

Only one I received not two. Bad experience. Not as described.
