Using this proprietary focused technology gives you the best clarity, dynamics, and detail from your movies and music. LINEAR TRAVEL SUSPENSION TWEETER Klipsch exclusive Linear Travel Suspension (LTS) aluminum tweeter minimizes distortion for enhanced, detailed performances. Using Kapton, an extremely light and rigid material, in the tweeter suspension provides high efficiency and improve resolution and detail. LTS tweeters are a hallmark of Klipsch speakers, making them some of the best speakers in the world. Spun Copper IMG Woofers Injection Molded Graphite (IMG) woofer cones are exceptionally light while being extremely rigid - providing remarkable low frequency response, with minimal cone breakup and distortion. In combination with the Tractrix horn-charged LTS tweeter, it delivers class-leading speaker efficiency. REAR TRACTRIX PORT The rear Tractrix port is perfectly matched to the cabinet and woofers, creating ideal airflow with minimal distortion or turbulence even at the lowest frequencies. High quality cabin design reinforced MDF construction reduces cabinet vibration for less audible colouring and improved sonic accuracy - Givi

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!

## Questions & Answers

**Q: Is it a Pair or single speaker ?**
A: Oh it should be a pair, I screwed up when I ordered and thought they were singles, so I ended up with eight speakers, had to send them back

**Q: Can these be hooked up through an RCA cable or just speaker wire?**
A: Speaker wire.  They have pretty nice connectors for wire or banana plug connections.  Rca connectors are usually for connecting a source to your receiver.

**Q: Does it have keyhole on back like the picture?**
A: Mine does

**Q: Viene el par o sólo un parlante??**
A: Es el par.

*by F***O on 25 December 2023*

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 5x4 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.
