Most important: What other stand-mounted loudspeaker lets itself be driven by low-powered, single-ended, directly heated triode amps with the air, punch, boogie, and resolution of the Klipsch Reference Premiere RP-600M? None that I know of. In my world, this speaker is a uniquely important discovery. Super-highly recommended..stereophile

The Klipsch Reference Premiere 600 was the Audiophiliac Speaker of the Year for 2018 because it sounded more alive and dynamic than any other speaker near its very reasonable  price The RP 600M is a lot of fun -- it's the sort of speaker that's hard to stop listening to. You just want to keep playing one more song, or even one more album. I love it when that happens. Cnet.com

 to Klipsch's proprietary hybrid Tractrix®horn - the RP-600M bookshelf speaker delivers incredible acoustics to fill your home with loud, crystal-clear sound and robust bass that no ordinary bookshelf speaker can.

90° X 90° SILICON COMPOSITE HYBRID TRACTRIX HORN

Horn loading maximizes efficiency and increases detail while focusing high frequencies toward the listening area. Proprietary Tractrix® geometry provides the most efficient transfer of high-frequency waves into the listening area. The phase plug and compressed molded silicon face ensure smooth frequency response. When combined, the cleanest, most natural sound possible is created. The second generation increases horn size for a larger soundstage and enhanced directivity.

LINEAR TRAVEL SUSPENSION (LTS) TITANIUM DIAPHRAGM TWEETER

The exclusive Linear Travel Suspension minimizes distortion for enhanced, detailed performance. LTS tweeters are a hallmark of previous Reference lines, making them a core component of some of the best speakers in the world.

VENTED TWEETER DESIGN

The vented tweeter housing reduces standing waves that create unwanted harmonics, resulting in enhanced detail and clarity in high-frequency reproduction.

CERAMETALLIC WOOFERS – ALL NEW DESIGN

A signature feature of the Reference Premiere series, Cerametallic™ woofers are exceptionally rigid and lightweight for minimal distortion and maximum efficiency. New voice coils are 70% larger in diameter resulting in improved power handling and greater cone control for greater linearity and flawless reproduction. New aluminum shorting rings reduce distortion as well as increase power handling and the new motor structure improves transit response with more control for greater speed and accuracy.

TRACTRIX PORTS

Utilizing Tractrix geometry, the Reference Premiere ports allow for the most efficient, fastest air transfer from the cabinet, which reduces port noise for punchier low frequencies. Klipsch Tractrix ports have custom-designed inner flares that help reduce air turbulence entering the port. Less turbulent air helps reduce port noise for cleaner, more powerful bass.

BI-WIRING / BI-AMPING CAPABILITY

Dual input terminals for bi-wiring / bi-amping capabilities. Bi-wiring separates high and low-frequency current into separate speaker cables, reducing intermodulation distortion, for a clearer midrange. Bi-amping allows for customization using outboard crossovers when using separate amplifiers.

NEW AND IMPROVED INPUT PANEL

Featuring audiophile-grade wire and easily accessible aluminum binding posts for any connection type.

FURNITURE GRADE MATERIALS AND FINISHES

Finishes include ebony vinyl and walnut vinyl that boast satin painted baffles with a scratch-resistant finish.

STRONG, FLEXIBLE, REMOVABLE GRILLE

Attaches magnetically for an elegant transition from powerful showstopper to discrete performance piece.

CORK PADS

Cork pads replace rubber bumpers for security on a stand or table.
