The R-51PM is a pair of powered bookshelf speakers with a built-in 60W-per-channel amplifier, so no separate receiver is needed. Each cabinet holds a 1-inch aluminum tweeter on a 90 x 90° Tractrix horn and a 5.25-inch copper-spun IMG woofer in a bass-reflex enclosure. Inputs cover Bluetooth, stereo RCA (switchable to phono for a turntable), optical, 3.5mm aux and USB Type-B. It suits desktop and small-room listeners who want horn-loaded Klipsch sound and a built-in phono stage, though it lacks HDMI and streaming apps that some powered rivals include.

Owners of the R-51PM series generally praise the lively, detailed Klipsch sound and the convenience of powered speakers with a phono input. Common complaints center on limited bass depth and a forward treble.
The Klipsch R-51PM is a pair of 2-way powered Bluetooth bookshelf speakers. Each speaker has a 1" aluminum tweeter on a 90 x 90° Tractrix horn and a 5.25" copper-spun IMG woofer. The cabinet is MDF with a bass-reflex design.
The speakers have a built-in 60W per channel amplifier. They connect wirelessly over Bluetooth. They also have stereo RCA, optical and 1/8" aux inputs for wired devices, plus a USB Type-B input for music stored on a computer.
The RCA input switches between line-level and phono. This lets you connect either a turntable or another wired source.
