1" Horn-Loaded Tweeter: The R-51M bookshelf loudspeaker
features Klipsch's proprietary Tractrix Horn technology mated with a 1" aluminum
LTS tweeter, for impressive high-end response and greater extension, enhanced
imaging and powerful dynamics.
Tractrix Horn: The square Tractrix Horn
delivers a 90° (w) x 90° (h) dispersion pattern for a broader sound-stage.
Klipsch exclusive Tractrix horn technology ensures that the speaker's high
frequency energy is aimed at the listener and reduces artificial reverb or
filtering caused by indirect sound bouncing off of walls. Using this
proprietary focused technology provides clarity, dynamics, and detail for
your movies and music
- LTS (Linear Travel Suspension): Behind each horn lies a
1.0" tweeter with a linear travel suspension. Klipsch exclusive Linear
Travel Suspension (LTS) minimizes distortion for enhanced, detailed
performances. In addition, Using Kapton (an extremely light and rigid
material) in the tweeter suspension provides high efficiency and improve
resolution and detail.
5.25" Copper-Spun IMG Woofer: The Klipsch R-51M bookshelf
speaker houses a single 5.25" Copper-Spun IMG woofer. The Copper-Spun
IMG (Injection Molded Graphite) woofer is exceptionally light while being
extremely rigid - providing remarkable low frequency response, with minimal cone
breakup and distortion.
Flared Port: The Klipsch Reference series bookshelf speaker
features a rear-firing port that is perfectly matched to the cabinet and
drivers. The port is precisely flared to minimize turbulence even at the lowest
MDF Cabinet: The Klipsch R-51M bookshelf speaker features a
MDF cabinet with a scratch-resistant, textured wood grain vinyl that
seamlessly integrates into almost any room or decor. The enclosure's reinforced
MDF construction reduces cabinet vibration for less audible coloration and
improved sonic accuracy.
Acoustically Transparent Grille: The Klipsch R-51M bookshelf
speaker comes with a removable, black cloth grille that is magnetic and
5-Way Binding Posts: The Klipsch Reference series bookshelf
speaker is fitted with sturdy 5-way binding posts to ensure a secure connection
to many types of cable and connectors. The 5-way binding post terminals will
accept banana plugs (single or dual), pin-connectors, spade-lugs and bare wire
(up to 10AWG). Two plastic caps will need to be removed to use banana plugs.
Mounting Options: The Klipsch R-51M can be placed on a
speaker stand, bookshelf, table, or other flat surface. The bookshelf loudspeaker comes with
self-adhesive rubber feet to secure the speaker in place and prevent any
damage to your stand's or shelf's surface. The rubber feet add approximately
0.3125" to the overall height of the speaker.
Note: There is no included bracket, keyhole slot, or threaded insert to
wall-mount the speaker.
Application & Placement: The Klipsch R-51M bookshelf
loudspeaker can be used in a dedicated stereo application or in a home theater
application as front and/or rear speakers.
- Front Placement: For optimum performance in a stereo
application or as front speakers in a home theater application, Klipsch suggests placing
the loudspeakers 6' to 15' apart. They may also be toed-in slightly for
better stereo imaging. The listening position should be about 1 to 1.5x the
distance separating the speakers.
- Rear Placement: When used as surround speakers in a home theater
setup, the loudspeakers should be placed approximately 2' above the
listening position. Typically this will be approximately 5' to 7' above the
floor. The surrounds should be placed on the walls directly adjacent to the
listening position. Another option would be on the wall behind the listening
Reference Series: The Klipsch Reference series consists of
four floorstanding speakers (R-610F/R-620F/R-820F/R-625FA), two bookshelf speakers (R-41/R-51M),
two center channel
speakers (R-34C/R-52C), and one
Dolby Atmos speaker (R-41SA)
- all sold separately. The Klipsch Reference series line-up of
loudspeakers sound great in stereo and home theater applications.
