Klipsch RF-7 III Floorstanding Speaker (Each) at Vinyl Sound Toronto Canada

The RF-7 III is the flagship floorstanding speaker of the Klipsch Reference Series (Hope, Arkansas, USA), available at Vinyl Sound in Toronto, Canada. Designed and assembled in Hope, Arkansas by Klipsch craftsmen, the RF-7 III features a 1.75-inch titanium diaphragm compression driver on a 90x90-degree compressed molded-rubber Tractrix horn, dual 10-inch spun copper Cerametallic cone woofers in heavy-duty cast aluminum frames, and a bifurcated dual-chamber bass-reflex enclosure with dual rear-firing Tractrix ports. With 100 dB sensitivity, a 32Hz to 25kHz frequency response, and 250W continuous power handling, the RF-7 III is available in Black Ash, Cherry, and Walnut furniture-grade wood veneers and is sold individually with dual binding posts for bi-wiring and bi-amplification.

90x90 Compressed Molded-Rubber Tractrix Horn and Titanium Compression Driver

The RF-7 III's high-frequency section pairs a redesigned 8.5-inch square Tractrix horn with an all-new 1.75-inch titanium diaphragm compression driver to deliver Klipsch's hallmark combination of high efficiency, controlled dispersion, and low distortion through the critical 1,300Hz to 25kHz operating range. The Tractrix horn uses a circular throat that expands into a square mouth geometry, a transition that produces more uniform dispersion across both horizontal and vertical planes simultaneously compared to a conventional circular mouth horn. The 90x90-degree coverage pattern ensures consistent frequency response across a wide listening area rather than narrowing the effective sweet spot to a small center region. The compressed molded-rubber construction of the horn body, rather than the rigid plastic or aluminum used in earlier Reference Series designs, provides inherent high-frequency damping that absorbs internal reflections and reduces the coloration those reflections introduce at the upper end of the horn's operating range. The new phase plug on the compression driver equalizes acoustic path lengths from across the titanium diaphragm to the horn throat exit simultaneously, improving phase coherency and producing more linear sound pressure output at high frequencies for cleaner, more detailed treble reproduction.

Dual 10" Cerametallic Woofers in Bifurcated Dual-Chamber Enclosure with Tractrix Ports

The RF-7 III's low-frequency architecture addresses the three primary challenges of housing dual woofers in a single cabinet: cone distortion at high excursion, internal standing waves, and port turbulence. Each of the two 10-inch Cerametallic woofers combines a ceramic-coated cone surface with a metallic substrate for exceptional rigidity at minimal mass, resisting the breakup modes that introduce distortion in lighter or less rigid cone materials during high-excursion bass transients. A cast aluminum frame eliminates the structural resonances that stamped steel frames develop under the mechanical stress of woofer operation, and a dual shorting-ring magnet structure cancels magnetic flux modulation during cone movement for more linear cone excursion with lower distortion across the full operating range. The bifurcated enclosure physically divides the cabinet into two independent acoustic chambers, assigning each woofer and its own dedicated Tractrix port to a separate volume. This prevents the two woofers from generating shared standing wave patterns that would otherwise create frequency response anomalies in the upper bass and lower midrange region immediately below the 1,300Hz crossover point. Each of the two rear-firing Tractrix ports applies horn-expansion geometry to the port profile, minimizing air turbulence at the port exit and producing cleaner, faster low-frequency output than conventional cylindrical ports at equivalent cabinet volume.

Frequently Asked Questions

What is the Klipsch RF-7 III?

The Klipsch RF-7 III is the flagship floorstanding speaker of the Klipsch Reference Series, designed and assembled in Hope, Arkansas. It is a two-way bass-reflex loudspeaker featuring a 1.75-inch titanium compression driver on a 90x90-degree compressed molded-rubber Tractrix horn, dual 10-inch spun copper Cerametallic woofers in cast aluminum frames, and a bifurcated dual-chamber enclosure with dual rear-firing Tractrix ports. It delivers 100 dB sensitivity, a 32Hz to 25kHz frequency response, and 250W continuous power handling from a 49-inch-tall cabinet available in Black Ash, Cherry, and Walnut wood veneer finishes.

How does the Klipsch RF-7 III compare to the Klipsch Forte IV or the JBL L100 Classic?

The RF-7 III and the Forte IV represent two different branches of Klipsch's speaker lineup. The Forte IV is a three-way Heritage Series design with a dedicated 1.75-inch polyimide midrange compression driver and Tractrix Mumps horn, a 15-inch passive radiator, and 99 dB sensitivity in a 36-inch-tall cabinet weighing 72 lbs. The RF-7 III is a two-way Reference Series design that sacrifices the dedicated midrange driver in favor of dual 10-inch Cerametallic woofers with greater bass extension to 32Hz, 250W continuous power handling, and a 100 dB sensitivity rating in a larger, more powerful cabinet. The RF-7 III is better suited to high-volume home theater environments and large listening rooms where output and bass extension are priorities. Compared to the JBL L100 Classic, which uses a three-way passive crossover with a 12-inch paper cone woofer at approximately 90 dB sensitivity, the RF-7 III delivers significantly higher efficiency, greater power handling, and substantially more dynamic headroom per amplifier watt.

What does the bifurcated dual-chamber design actually improve?

The bifurcated enclosure of the RF-7 III divides the cabinet into two physically isolated acoustic chambers, each housing one 10-inch woofer and one Tractrix port. In a conventional single-chamber enclosure housing two woofers, the shared internal air volume creates standing wave resonances at frequencies determined by the cabinet's internal dimensions. These standing waves produce narrow peaks and nulls in the bass response that are most audible as colorations in the upper bass and lower midrange region near the crossover frequency. By isolating each woofer in its own independent chamber, the bifurcated design prevents these shared resonances from developing, allowing each woofer to behave as a clean, well-controlled bass radiator without acoustic interference from its partner, improving midrange cleanliness and overall tonal accuracy through the crossover region at 1,300Hz.

What is the difference between the Klipsch RF-7 III and the RF-7 II?

The RF-7 III introduces several meaningful upgrades over the RF-7 II. The titanium compression driver features a new phase plug design that improves phase coherency at the horn throat, producing better sound pressure linearity at high frequencies. The Tractrix horn has been redesigned with compressed molded-rubber construction, replacing the rigid material of the RF-7 II's horn for improved high-frequency damping and reduced harshness. The bifurcated dual-chamber enclosure is new for the III, replacing the shared single-volume enclosure of the RF-7 II and eliminating the standing wave problems that affected the earlier design. The dual Tractrix ports are also new to the III, providing more efficient and cleaner low-frequency venting than the RF-7 II's conventional port geometry.

What amplifiers pair well with the Klipsch RF-7 III?

The RF-7 III's 100 dB sensitivity and 8-ohm nominal impedance make it compatible with a broad range of amplification from AV receivers to dedicated high-power stereo amplifiers. For home theater use, AV receivers from Marantz, Denon, and Anthem with 100 to 200 watts per channel provide ample power and the DSP room correction needed to optimize the RF-7 III in real listening rooms. For two-channel music listening, high-current solid-state integrated amplifiers from brands such as Rotel, Hegel, and Musical Fidelity provide the bass control and dynamic authority that the dual Cerametallic woofers reward. The RF-7 III's 250W continuous power handling also makes it suitable for pairing with professional-grade power amplifiers in dedicated reference-level listening setups.
