Pretty great pair of speakers. I had purchased them on sale so I thought, why not? Size wise, they were a bit large but no larger than other bookshelf speakers in its category. I'm not the most eloquent person, but I would say that the sounds of the speakers had plenty of clarity and was not muddied by the equally great bass. Pretty awesome pair for any fans of more colorful audio than the dry analytical sounds of more accurate ones. Would recommend a subwoofer though.

I purchased these R-51 M speakers as a rear channel for my home theater system. They are replacing my Bose Acoustimass 10 system. With only these connected and using the Klipsch RP-404C Center Channel, the sound is phenomenal. It's like I bought an entirely new system. There is a very noticeable sound quality difference. I'm running them through the Onkyo TX-NR656 amplifier. Also purchased at Best Buy. At this moment my sub and front speakers have not arrived. I purchased these through Best Buy's "open Box" program at a deep discount. They look and sound new. Keeping in mind I would have removed them from the box anyway to connect them. Best Buys loss is my gain, Thanks Best Buy. There is one drawback . Best Buy does not offer any reasonably priced speaker stand to match these speakers. Nor does Klipsch. I can live with that. I'm fairly handy so I will just make a custom set. This is necessary for my application. As stated these are my rear channel speakers. The connection is very simple. No degree needed. If you can screw a tire valve cap on, you can connect these with out difficulty. They weigh eleven pounds each. So rather than chance many of the stands offered and having my speakers crash to the floor I feel this to be my best option. Would I recommend these speakers? By all means. This is a reasonably priced, high quality addition most would be proud to have in their system. One final thought. Don't pass by those "open box" offers. You get good first quality at a reduced price when available.

I needed some speakers to use for rears that would somewhat match tonally with my Klipsch RP-150m fronts and RP-500C center. I was on a budget and got these for half price Black Friday. Timbre matching is not as critical for the rear speakers but these seem to be voiced similarly to the Reference Premiere line. Even when I listen to my SACDs in 5.1, the music pans from front to rear, the speakers blend in perfectly. Only complaint is on stock photos, there appears to be a keyhole on the back to hang the speakers on the wall. There is no keyhole on the back of the speakers so you have to come up with your own mounting method if you need to hang them. The magnetic grille covers are a nice touch that's rare in the price range. I appreciate the full size tweeter horn vs the smaller ones used on the previous R-15M, it really improved the tweeter dispersion. Really great speakers for the price that sound bigger than they are.

I got these half off during the Black Friday promotion. At half price they are an exceptional value. I personally bought two pair to use as side and rear surround speakers, in conjunction with higher grade Klipsch Reference Premier RP-250F front and RP-450C center speakers. They fill this role well, with very similar sound completing the sound stage for gaming and movies. I've also seen these demo'd in a store playing rock and roll tracks in a 2.1 configuration as primary front speakers along with a subwoofer. I was shocked at how much volume they put out into the large open space and sounded great paired with a sub. My only reservation is I will say Klipsch seem pretty directional. If I walk from my open concept living room into my kitchen, there is a change in the character of the sound once you aren't 'in the zone'. Your experience may vary depending on your room characteristics. The attached picture shows how their similar dimensions and design compares to the RP-250F.

Great speakers. I have these set up to use as primary’s for my Fluance RT-85 turntable. I went to my local goodwill and found and older Onkyo receiver for $15 that had phono output and hooked these up to it. Played the ol Elton John H. Chateau album and WOW I impressed with these speakers. They take what you throw at them clear, crisp and effortlessly. Crank up the volume?,sure why not. They don’t t blink an eye. Needless to say these are a definite buy if you’re in the market for really nice passive bookshelf speakers.
