Klipsch R-51M Bookshelf Speaker (Pair), Black

The r51ms are used to compliment my klipsch rp500m speakers and a 12 inch subwoofer in a large living room. By placing the r51m speakers to the outside walls , and the rp500m speakers to the interior, closer to the amplifier, and with the subwoofer set on deep bass only at just enough volume to barely compliment the sound, the large living room is more than sufficiently covered with at least true high fi quality sound, if not true budget audiophile sound. My entire 2.1 system is all klipsch. That's how I want it. I am using them with a high powered tube amplifier, so presence and clarity is awesome. Placement is critical. I was initially disappointed until I switched the r51ms to the spread to the outside walls position, and the rp500ms to the interior, closer to the amplifier. The difference was remarkable. The 2 different klipsch speakers, ie one a rp and the other a r series blend together perfectly with no clash whatsoever because of somewhat more refined sound on the rp500m speakers. The rp500m speakers do sound higher end , but they are supposed to, but with the speakers as outer r51m and inner rp500m, and the klipsch subwoofer at deep bass with just a touch of volume the result is sound of such quality that I can honestly say I can be content and satisfied with it. I can say my system is complete, and no further improvement, upgrades are needed. Tower speakers as primaries are not necessary because of the high quality of sound and the high sensitivity of the 4 klipsch bookshelf speakers and klipsch subwoofer. This saves me money during this rapid inflation period of time. I could easily say that what I have sounds more than good enough to be satisfied and content with without any desire to upgrade further at this point. Shipping speed was excellent via Amazon itself, and the box and speakers arrived in handled with care and new condition. I am not disappointed at all now that the r51m speakers are the outside speakers, spread apart from corner wall to wall to compliment the interior placements of my rp500m speakers by klipsch. Im all klipsch here and I love it. 5 stars categorically. As previously stated, I see no need for primary tower speakers, even in a large living room, and that equals high quality sound and savings of money at the same time. I recommend these speakers. They do more than just do sound quality wise.

I have Klipsch center and front speakers, and a Klipsch sub, so all I needed were matching surround speakers. I love the copper look of Klipsch! These were well packaged, so no damage. A good size for sitting on end tables. Cost wasn’t bad, and I got it on sale. It seemed like they were discounting these periodically as I had my eyes on these a while. Nice loud speakers for their size, Klipsch is good at being very power efficient, so more volume for its size. As for other speaker details, I recommend looking at Crutchfield audio website to learn specific details about these if you are debating what speakers you want.

Sound quality, the quality of materials used to manufacture product is exceptional (a rarity these days), price, aesthetically pleasing, clarity of sound, range is exceptional. So far I've only used these on my home built desktop with an external amp, and with a software equalizer these little giants put out some quality audio. I plan on hooking them up to one of my TV's next for the full home-theater experience.

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.

This is my first pair of "Klipsch" speakers. But they are most definitely the nicest pair of bookshelf speakers I've ever owned so far! My last pair were the Micca bookshelf speakers. These are a very big improvement. Very clear with outstanding power handling. I bought mine during the "Black Friday" sale, so definitely worth the money!

A good all-around pair of starter speakers if you're planning on using them as standalones. These will have zero trouble filling a small to medium sized space with rich and detailed sound at low to mid volumes. The bass is adequate for their size. They're not going to knock your socks off on more thumpy genres. I would imagine pairing them with a subwoofer would make quite the difference but for rock and some synth pop, they're pretty sweet. Plus the copper woofers look very striking without the faceplates. That said, I say these are best suited at low to mid volumes because cranked, the higher frequencies can be awfully fatiguing coming out of these speakers. I would not pay anywhere close to the $349 MSRP for these (you can probably find a pair of far superior RP-600Ms for around that price nowadays). Around $150 seems like a sweet spot for the R-51Ms, but the Sony SSCS5s and Fluance Signature bookshelfs are very comparable, if not better sounding for around the same price. Still, these will probably more than satisfactory if you're not expecting to be blown away by them. UPDATE 5/20/25: Can confirm that the subwoofer made a big difference. I was going to retire these since I replaced them with some bigger floor speakers on my main setup but I decided to try them out in place of the factory speakers on the Klipsch ProMedia 2.1 I have hooked up to my computer. Not only does the onboard amp seem to drive them okay at not-insane levels of volume - they sound really sweet paired with the 6.5-inch subwoofer. While I won't change my rating, I do highly recommend getting a sub along with these speakers.

Fantastic pair for 2.1 stereo or as a high end addition to full surround. Even as main fronts or studio monitors these are phenomenal value. Never buy a pre-built again, a simple DAC amp or receiver with a powered sub is way better bang for the buck. Crystal clear audio at very low volumes as well as very loud. They respond excellent to software equalization, capable of some bass on their own if you don't want a full subwoofer with them (highly recommend 10" or larger subwoofer). The sensitivity is such that even a simple amp can drive these very well for an 8ohm passive speaker, which is great for small units or a cottage or apartment. They're very bright in sound thanks to the horn shape tweeter space, but if you keep the magnetic shields on it attenuate the high end just a little for a personal preference adjustment. After breaking them in for a week there's no hissing, whine, static, fuzz, or any discernable audio when playback is stopped so careful not to leave them on, there's almost no way to tell just by listening for electrical noise. These pack a punch, they're very clean in looks and sound, but if you're into warm sound (lows and mids emphasized) rather than bright, clean vocals and instruments this brand may not be your best fit. These are amazing for all types and styles of music, and especially movies / games with that clear high end though, so I'd recommend them to anyone on a budget who wants an upgrade from even the best all-in-one stereos available. Build a system with these speakers and a small amp and you'll have a system to gush over for years to come since these can be added on to any high end home theatre solution at any price range down the line.

These R-51M bookshelf speakers have been on my Wishlist since I first listed to them a year ago. To be clear, I am not a big fan of the so called "Klipsch sound"; however, these speakers can sing beautifully! Paired with a Harman HK3490, a Harman AVR171/171S, or an Onkyo TX-RZ50, the sound you get out of these is unmatched for the price point in my opinion. Although these do not go very low, the bass performance you get from 100Hz and below is quick and punchy, though you will require a subwoofer if you mean business. Now, the stars of the show; the mid range and high notes! I cannot even begin to describe how awesome these sound! The mid range is very clean with sublime vocals, and the top range is so detailed and provides insane clarity. I had these hooked in to my receiver for a good time and never felt fatigue, which I usually get rather fast with other Klipsch speakers I listen to. If you're one of those who are after clinical tests of neutrality, I doubt that these speakers are for you. However, if you forget graphs for a second and give these a listen if you can demo them somewhere, I am sure you'll hear a lot to appreciate. I used these as my main speakers for listening in the near field and in a mid-sized room with no treatment. Finally, I also think the R-51M looks beautiful with those silver screws contrasting the black baffle, the copper drivers, and the tweeter's horn. I find them very pleasing to look at with the grill too but mostly without it. To sum up, these are very clear and detailed sounding speakers with reference-level audiophile performance. They are very dynamic, engaging, and fun to listen to, and they're a bargain at the current price for the performance you get. For reference, my main audiophile system is based on a pair Focal Chora towers, so if I like the sound of these, it speaks volume about the value for money you get from the Klipsch R-51M!
