Product description

The QRP40/120 is a 2-way column loudspeaker to be used as vertical sound system, for both permanent and portable applications. Its slim design packs a perfectly natural, dynamic sound reproduction with superb intelligibility, coverage and throw.

It is specifically designed for applications where ultimate fidelity response needs to be projected with a very precise coverage, ideal in acoustically challenging environments, or applications where intelligibility-over-distance is required.

Loaded with the RBN1203 12” / 30cm pro-ribbon driver on a “Morpher” lens, the system offers an exceptional, SPL-independent throw-efficiency and projection control, due to the pro-ribbon’s all-natural cylindrical (isophasic) wavefront. The patented 120-degrees horizontal dispersion offers a consistent audience coverage up to the highest frequencies.

Its fast impulse response, “compression-less” principle and unusual high peak power handling of (2000W @ 200ms) cater for a perfect intelligibility from the lowest to the highest SPL with a 1:15 dynamic range, while offering a maximum “gain-before-feedback”.

The RBN1203 driver is mounted in a co-axial speaker configuration with eight woofers in a sealed cabinet. The custom-design 5” woofers feature Active Coil™ technology for extremely low-distortion LF reproduction, a perfect match with the MHF pro-ribbon technology. The acoustic length assists the QRP40 in an extended vertical projection control in the low-mid frequency range, at the same time enabling a smooth but powerful roll-off to additional subwoofers.

The frequency response roll-off enables an excellent partnering with an additional subwoofer, like the QB363.

The system brings the unsurpassed clear, dynamic and ultra-low distortion Alcons signature sound in a very slim and unobtrusive package; The M10 mounting points on top and bottom and the M6 universal mounting bracket pattern on the back, together with the optional ACO™ color scheme provides for an inconspicuous, low-profile presence in any application.

The QRP40 is powered and controlled by the ALC amplified loudspeaker controller; offering QRP40-specific drive processing, delivering absolute maximum sound quality with increased headroom and utmost operation reliability and flexibility.

The QRP40 is available in two versions with 90-degree (QRP40/90) and 120-degree (QRP40/120) horizontal dispersion.
