Title: Quality Sound and Appearence.
Review: I recently purchased the Klipsch R-51M Bookshelf Speakers (Pair) in black, and I am absolutely thrilled with their performance! These speakers are an incredible upgrade to my home audio setup. The sound quality is truly impressive—crystal-clear highs, punchy mids, and deep, well-defined bass. Whether I’m listening to music, watching movies, or gaming, the sound is dynamic and immersive.The build quality is top-notch, with a sleek and modern design that fits perfectly in my living room. The black finish looks elegant and complements any décor. Despite their compact size, the R-51M speakers deliver powerful sound that fills the room effortlessly.The installation process was simple, and they are very easy to integrate with my existing system. The 5.25-inch woofer and 1-inch tweeter really deliver in terms of detail and clarity, and I’ve noticed a significant improvement in sound quality compared to my previous speakers.Overall, I couldn’t be more satisfied with the Klipsch R-51M Bookshelf Speakers. They provide excellent value for the price, offering superior sound and an attractive design. If you’re in the market for bookshelf speakers that deliver exceptional performance, these are an excellent choice! Highly recommended!

Title: Happy with this addition to my surround sound
Review: Added these to me klipsch reference home theater pack and relocated the 2 smaller speakers to rear and went 7.2 surround. These speakers are nice, they add a lot of quality to my system with clean sound and since i got 2 subwoofers the bass is nice and deep. Overall happy. I do believe klipsch speakers are overpriced so I always grab when they are super discounted or I get a used set from a reputable seller. I would say the 179 i paid made it worth it over full retail.

Title: Fabulous!
Review: They are great! Very punchy and detailed. However, to make the most of these you’ll need to buy the Klipsch 10″ sub. You won’t be sorry. It really makes the whole system come alive.Remember, out of the box the speakers are a little stiff. It’ll take about 10-15 hours of signal to break them in. Then, they sound fabulous!

Title: Great starter speakers – for the right price.
Review: 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.

Title: Fantastic speakers
Review: Why did you pick this product vs others?:Very pleased with this speaker.   It is way better than my expectation at this price range.  I reviewed also much higher price Kef R3 Meta which may be better sound for some but cannot beat the price of this Klipsch speakers. Use these as main front speakers in a surround sound set up with Denon receiver.  The sound is fantastic for listening to music or watching movies.  Highly recommended for quality and pleasant sounds which does not break the bank.

Review: 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.

Review: 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!

Review: Menciono otra vez que no soy profesional del audio y aprendo de los videos de YouTube.Llego bien la caja, sin daños y adentro de otra caja.Buen sonido, pero se escucha mejor separando las bocinas entre sí unos 4 metros, las tengo en una sala de 5×4 metros, con muebles y sin acondicionar.Alimentadas por un amplificador SMSL AO200MKII y con Deezer.Pero llega un momento que se distorsiona con los graves a un alto volumen, no es lo suyo los graves, hay que bajar los gravez. Los medios creo, se escuchan mas o menos.Pero es necesario añadir un subwoofer y asi se escucha la diferencia, realmente se realza la calidad del sonido añadiendo un subwoofer. Las considero unas bocinas suficientes para llenar mi sala a buen volumen ( un poco alto) y buena calidad de audio.Son las primeras bocinas que adquiero. No se como sonaran otras marcas , pero para empezar, valio la pena la compra. Ademas, con opcion de pago accesible.

Review: Comprei essas caixas para usar com um receiver stereo no escritório e me atenderam muito bem.Não são caixas refinadas e nem para ambientes grandes, mas tocam muito bem, não causam fadiga auditiva e atendem desde que sejam utilizadas da maneira correta.Sendo assim, se você precisa de uma caixa com visual bacana, com um som que não decepciona, com um ótimo custo x benefício, elas irão lhe atender perfeitamente.São bem construídas, a tela de proteção é com imã e a embalagem é bem bacana e proteje muito bem o produto durante o transporte.
