Great speakers, rich full sound
Size: Pair
These are really great speakers. I got them to go with my husband's new record player for Christmas. These really sound fantastic. A rich range, with a nice bass that's not too much. They were easy to connect to the player. I like a rich sound better then bright (I think if it's too bright it doesn't have enough bass), and these definitely fit the bill. I got these on a black Friday deal which was even better. They are a good value for the quality.

The new amp/speaker configuration made a very noticeably positive difference.
Size: Pair, Size: Pair
I bought a Denton amp / Klipsch 7 speaker bundle for Christmas last year. It sounded impressive. For this year, I recently replace the Denon AVR-S970H, a 5.2.2 POS-Amp that quit after less than a year. Then I also added a 70” TV and a set of R-51M’s on the sides. I could never hear this amp driving the Dolby Atmos speakers on top of the R-625FA towers, so I decided that back speakers would be more beneficial to this 7-channel system. I’d been using the R-41M’s that came in the bundle as side surround speakers, but I was thinking that they would be more suited for use in back. So I replaced them with a new set of R-51M’s that I thought would be better surround sides because of their fuller stronger sound. As of now, at the front of this theater system is an Onkyo TX-RZ 820 AVR amp, a 70 inch LED 4K smart TV, a set of Klipsch R-625FA towers, an R-52C Center Channel Speaker, and two R-12SW Subwoofers. For the surround sides is the newly purchased set of R-51M’s on stands, and mounted on the back-wall is the set of R-41M’s, using BS-218pro Wall Mounts. For good reason, this is a very powerful amp driving a complete set of purely Klipsch speakers. I built this THX 7.2.0 surround sound system to go in my wife’s 11’ X 12’ privacy room, specifically because she is hard of hearing. She said, that with the new additions, the sound is much cleaner, stronger, the 3D surround effect is more noticeable, and the vocals are easier for her to understand. I get to use it sometimes when she’s not at home. Thunder in movies sounds as crisp sharp and loud as real thunder. All around, the system is very realistic sounding. And it can play music, shaking the house at live levels. At present, my wife and I are extremely happy with this system. It sounds as good as it looks. The Klipsch speakers & Onkyo amp configuration makes a very noticeably positive difference.

Great value speakers for a beginner audiophile
Size: 4” Woofer
Fantastic sound quality to my ears, got these used “mint” for 179 and that was a steal, they were never even opened. They feel solid and well made, they’re heavy for the size which makes them feel of a higher quality. Very happy with my purchase
