Klipsch RCC-112 LCR Real Custom Cinema Behind-the-Screen Speaker at Vinyl Sound Toronto Canada

The RCC-112 LCR is a professional-grade behind-the-screen cinema loudspeaker from Klipsch (Hope, Arkansas, USA), available at Vinyl Sound in Toronto, Canada. Part of the Klipsch Real Custom Cinema Series, this individual LCR channel speaker is engineered for acoustically transparent screens from 112" to 121" wide, in 16:9 or widescreen formats. It features a 3" K-691 titanium diaphragm compression driver on a K-510-M 90°x60° Tractrix Horn, a 15" K-45-ST polyfiber cinema woofer, and delivers a system sensitivity of 107 dB with 130 dB maximum continuous SPL per the full RCC-112 system. Designed and handcrafted at the Klipsch factory in Hope, Arkansas using the same acoustic components found in Klipsch's professional cinema speaker range, the RCC-112 LCR brings commercial cinema-grade performance to large dedicated home theater and media rooms.

Professional Cinema Components Behind an Acoustically Transparent Screen

The Klipsch Real Custom Cinema Series draws directly on decades of professional cinema loudspeaker engineering, using the same acoustic and network components deployed in Klipsch's commercial cinema installations worldwide. The RCC-112 LCR uses the K-691 3" titanium diaphragm compression driver and K-510-M Tractrix Horn, a large-format cinema HF driver pairing that provides the headroom, low distortion, and controlled 90°x60° coverage required for high-output, high-intelligibility left, center, and right channel reproduction behind a full-width acoustically transparent screen. The K-45-ST 15" polyfiber woofer handles low-frequency reproduction with the excursion and power handling necessary for cinema dynamics that demand sustained peaks well above reference level. Both drivers are loaded into a double-braced dado and rabbit-joint MDF enclosure just 20.25" deep, designed to sit flush within a false wall or screen frame build-out without protruding into the room or requiring custom cabinetry beyond the standard false-wall construction the RCC system is engineered around. Each RCC-112 LCR is labeled and signed by the Klipsch craftsperson who built it, and ships with a printed certificate of authenticity confirming its made-in-the-USA provenance.

Modular False-Wall Design for No-Light-Creep Installation

The RCC-112 LCR is conceived as part of a fully integrated behind-the-screen system architecture that eliminates the acoustic and visual compromises of traditional home cinema speaker placement. The modular false-wall design positions the LCR speakers, and the accompanying RCC-112 subwoofers, behind a single acoustically transparent screen surface that spans the full width of the front wall. The enclosure geometry and the system's modular bundle configuration are engineered to provide complete coverage of the screen width from 112" to 121" without gaps in the acoustic output zone, while the false-wall build-out blocks all light paths behind the screen to eliminate the light creep that degrades image contrast in screen-masking and ambient-light-rejection screen systems. The installation process is deliberate in its simplicity: determine the screen width, order the appropriate RCC part number, build or cut the false wall to the Klipsch architectural drawing dimensions, place the speakers, connect the wiring, and hang the screen. No custom acoustic treatment of the speaker enclosures is required. The system also supports both mono-amp operation via the internal passive crossover and bi-amp operation via an external active crossover, giving integrators the choice of simplified single-amplifier wiring or optimised bi-amplified performance for reference-grade systems.

Frequently Asked Questions

What is the Klipsch RCC-112 LCR?

The Klipsch RCC-112 LCR is an individual left, center, or right channel behind-the-screen cinema loudspeaker from the Klipsch Real Custom Cinema Series, engineered for acoustically transparent screens from 112" to 121" wide. It uses the same K-691 3" titanium compression driver, K-510-M Tractrix Horn, and K-45-ST 15" polyfiber woofer components found in Klipsch's professional cinema loudspeakers, assembled in a double-braced MDF enclosure just 20.25" deep for false-wall installation. The full RCC-112 system, which includes three LCR speakers and two 18" subwoofers, delivers 107 dB system sensitivity and 130 dB maximum continuous SPL, making it one of the most capable behind-the-screen speaker systems available for large dedicated home theater installations.

How does the Klipsch RCC-112 LCR compare to the Seymour-Screen Excellence Stainless system?

The Klipsch RCC-112 LCR and Seymour-Screen Excellence cinema speaker systems both target large dedicated home theater installations with behind-the-screen speaker placement, but differ fundamentally in driver technology and output capability. The RCC-112 LCR uses a professional cinema 3" titanium compression driver on a Tractrix Horn, a large-format horn-loaded architecture that delivers 107 dB system sensitivity and 130 dB maximum continuous SPL at the system level, matching professional cinema auditorium output standards. The horn-loaded topology also provides tighter, more controlled 90°x60° directional coverage across the screen width, reducing room reflections and maintaining intelligibility at high output levels. The RCC-112 LCR's professional cinema component lineage, made-in-the-USA provenance, and certificate of authenticity also reflect a level of quality verification and build documentation uncommon in home theater speaker categories at any scale.

What screen types is the Klipsch RCC-112 LCR compatible with?

The Klipsch RCC-112 LCR is designed for use behind acoustically transparent screens in 16:9 or widescreen format, for screens from 112" to 121" wide. Acoustically transparent screen materials allow the LCR speakers to project sound through the screen surface with minimal acoustic attenuation, placing the audio image precisely at the screen plane for a natural correlation between the visual image and the sound field. Common compatible acoustically transparent screen types include perforated vinyl, woven fabric, and micro-perforated surfaces from manufacturers such as Stewart Filmscreen, Elite Screens, Screen Innovations, and Draper. The screen manufacturer's published acoustic transparency specifications should be verified to confirm compatibility with the RCC-112 LCR's output and frequency response range before final system design.

Can the Klipsch RCC-112 LCR be bi-amplified?

Yes, the RCC-112 LCR supports both mono-amp and bi-amp operation. In mono-amp mode the internal passive crossover divides the signal between the 15" woofer and the 3" compression driver, allowing a single amplifier channel to drive the complete speaker from a conventional stereo or multichannel processor output. In bi-amp mode an external active crossover is used to split the signal before amplification, allowing separate amplifiers to drive the low-frequency and high-frequency sections independently. Bi-amp operation provides greater headroom in each frequency band, reduces intermodulation distortion between the woofer and compression driver circuits, and allows individual gain adjustment of each driver section for room EQ purposes in reference-grade installations. Klipsch provides active crossover settings documentation for the RCC-112 system to support integrators configuring bi-amp deployments.

Where can I buy the Klipsch RCC-112 LCR in Toronto or Canada?

What amplifier power is recommended for the Klipsch RCC-112 LCR?

Klipsch recommends a minimum of 250 watts RMS per channel for each RCC-112 LCR in the system. Given the LCR speaker's 107 dB system sensitivity and 400W continuous power handling, a professional multichannel amplifier rated at 250W to 400W per channel into 8 ohms is the appropriate specification range for most reference-level home cinema systems. For bi-amp configurations, separate amplifiers are required for the HF and LF driver sections of each LCR channel. Professional multichannel amplifiers from manufacturers such as Crown, QSC, Anthem, and Datasat are commonly paired with the RCC-112 system in high-performance home theater installations.

How many RCC-112 LCR speakers are needed for a complete front stage?

A complete front LCR stage for a standard home cinema installation requires three RCC-112 LCR speakers: one for the left channel, one for the center channel, and one for the right channel. The full RCC-112 BTS (behind-the-screen) system bundle includes all three LCR speakers plus two RCC-112 subwoofers with K-49-EP 18" polyfiber drivers, covering the complete front soundstage and subwoofer bass management for screens from 112" to 121" wide. The RCC-112 LCR is also available individually, as listed here, for integrators who require individual channel replacement or who are configuring a custom front stage with differing sub placement. Klipsch Professional cinema surround speakers and THX Cinema Series speakers are available separately to complete the surround and overhead sound field for Dolby Atmos and DTS:X configurations.

What makes the Klipsch RCC-112 LCR different from conventional home theater speakers?

The Klipsch RCC-112 LCR differs from conventional home theater loudspeakers in component specification, installation format, and output capability. Its 3" K-691 titanium compression driver is a professional cinema driver, significantly larger than the 1" or 1.5" compression drivers used in most home theater horn-loaded designs, providing substantially greater headroom and lower distortion at the output levels required to fill a room sized for a 112" to 121" screen. The horn-loaded topology delivers 107 dB system sensitivity, versus the 85 to 92 dB sensitivity typical of conventional home theater floorstanding speakers, meaning far less amplifier power is required to reach reference cinema levels. The behind-the-screen false-wall installation format places the audio image precisely at the screen plane rather than beside or below it, eliminating the spatial disconnect between the visual and audio image that is inherent in conventional speaker placement on either side of a front projection screen.
