Klipsch RP-600M II Hi-Fi Bookshelf speaker Ebony

Klipsch RP-600M II Ebony — High-Efficiency Bookshelf Speaker with Horn-Loaded Precision

The Klipsch RP-600M II Ebony bookshelf speaker delivers horn-loaded dynamics in a compact stand-mount format. Built on the Reference Premiere II platform, it pairs a titanium tweeter with a Cerametallic woofer for full-range sound. The 44 Hz to 25 kHz response covers the full audible spectrum with authority, while 94 dB sensitivity delivers satisfying volume even from low-wattage tube amplifiers. This makes it a flexible choice for diverse system configurations, from single-ended triode setups to high-current AV receivers.

Larger Horn, Revised Woofer, and Audiophile-Grade Connectivity

What sets this speaker apart is the enlarged 90°x90° silicone composite Hybrid Tractrix horn, which transfers high-frequency energy more efficiently than the previous generation. The redesigned 6.5" Cerametallic woofer incorporates a 70% larger voice coil and aluminum shorting rings for reduced distortion. Dual anodized aluminum binding posts accept banana plugs, spade lugs, or bare wire up to 10 AWG, enabling true bi-wiring or bi-amping with separate outboard amplifiers.

Horn-Loaded Tweeter and Cerametallic Woofer — The Heart of the Sound

The driver complement defines this speaker's character. The 1" LTS (Linear Travel Suspension) titanium diaphragm tweeter operates within a vented housing that reduces standing waves behind the diaphragm. The matching Cerametallic woofer uses a rigid, lightweight cone material that holds shape under high excursion while maintaining speed and accuracy.

• Tweeter: 1" titanium LTS with vented housing — delivers detailed, low-distortion highs
• Horn: 90°x90° Hybrid Tractrix with silicone face — controls directivity for a wider sweet spot
• Woofer: 6.5" Cerametallic cone with 70% larger voice coil — handles power with speed and accuracy

Frequency Response, Sensitivity, and Power Handling

These specifications determine how the speaker behaves in real rooms and with real amplifiers. High sensitivity means less amplifier power is needed for the same output, while wide frequency response ensures both deep bass and extended treble are reproduced faithfully.

• Frequency Response: 44 Hz – 25 kHz — full-range coverage from deep bass to airy highs
• Sensitivity: 94 dB — efficient enough for 2–4 watt SET tube amplifiers
• Power Handling: up to 100 W RMS (400 W peak) — compatible with a wide range of amplifiers
• Impedance: 8 ohms — stable load for most AV receivers and integrated amps

MDF Cabinet, Tractrix Port, and Bi-Wire Terminals

Internal bracing and the rear-firing Tractrix port work together to reduce cabinet vibration while delivering clean bass output. Dual binding posts enable bi-wiring or bi-amping for users who want to extract maximum performance from their electronics.

• Cabinet: MDF with ebony vinyl finish and satin-painted baffle — furniture-grade appearance with reduced resonance
• Port: Rear-firing Tractrix geometry — minimizes turbulence for cleaner low frequencies
• Terminals: Dual aluminum binding posts (bi-wire/bi-amp capable) — accepts banana plugs, spade lugs, or bare wire
• Dimensions: 203 x 402 x 332 mm — compact stand-mount footprint
• Weight: 8.2 kg per speaker — solid feel without being unwieldy

Ideal for Audiophiles, Home Theater Builders, and Low-Wattage Tube Amp Lovers

This bookshelf speaker suits listeners who want horn-loaded dynamics and high efficiency in a compact form factor. It pairs naturally with low-wattage SET tube amplifiers thanks to its 94 dB sensitivity, yet handles high-current solid-state power with equal ease. Home theater enthusiasts can deploy it as front or surround channels within a full Reference Premiere II system. Music lovers seeking detailed mids, controlled treble, and tight bass will find it delivers across genres from classical to rock.

The Klipsch Reference Premiere Legacy

Klipsch has engineered horn-loaded speakers in the USA since 1946, and the Reference Premiere series represents the brand's modern expression of that acoustic heritage. The original RP-600M was named Speaker of the Year by Audiophiliac in 2018 and became a budget reference for countless reviewers and listeners. This Mark II version builds on that foundation with a larger horn, revised woofer motor structure, and premium anodized aluminum binding posts — a worthy evolution of one of the most beloved stand-mount speakers of the past decade.
