Klipsch R-51M

The Klipsch R-50M bookshelf loudspeaker has a power handling capability of 85 watts RMS (up to 340 watts peak) with a sensitivity of 93 dB, making it suitable for use with most hi-fi and home theatre amplifiers on the market.

It incorporates a larger Tractrix horn, running from one edge of the speaker to the other. Combined with a 2.5 cm aluminium dome tweeter, the new Tractrix horn significantly improves the propagation of mid and high frequencies towards the listener, resulting in a more accurate spatialisation of the soundstage. The Tractix horn also increases the efficiency of the tweeter in the mid frequencies, thus requiring less power from the amplifier. In addition, the tweeter is mounted on a Kapton LTS suspension, which provides excellent damping of body vibrations. Therefore, the sound emitted by the Klipsch R-51M is easily intelligible, accurate and affected by very little distortion.

The Klipsch Reference R-51M uses a 5.25" diameter low-end driver. Its copper-coated TCP (Spun-Copper Thermoformed Crystalline Polymer) cone adopts a crystalline structure that makes it structurally stronger and stiffer, while maintaining its light weight. This improves the impact and responsiveness of the diaphragm while preventing degradation caused by repetitive movements. The loudspeaker is housed in a slightly larger enclosure than the previous generation, which increases the volume loading and consequently reduces the low-cut frequency to 58 Hz. Of course, this speaker can be combined with a subwoofer for even better bass response and impact.

The Klipsch Reference R-51M is housed in an MDF cabinet with a black wood-look textured vinyl finish. The absence of visible screws on the front panel and the larger Tractrix horn give it a very elegant look. The speaker comes with a magnetically attached speaker grille.

The Klipsch R-51M bookshelf loudspeaker covers a frequency range of 62 Hz to 21 kHz. Its power handling capability is 85 watts RMS, with the possibility of handling up to 340 watts peak. Its high sensitivity (93 dB) and 8 ohm impedance allow it to be used with most hi-fi and home theatre amplifiers, even those of modest power. It can be used both for hi-fi listening as a main speaker and in a home theatre system as a surround speaker.
