description
The QRP40/90 is a 2-way column loudspeaker to be
used as vertical sound system, for both permanent andportable applications. Its slim design packs a perfectly
natural, dynamic sound reproduction with superb
intelligibility, coverage and throw.

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”.

It is specifically designed for applications whereultimate fidelity response needs to be projected with avery precise coverage, ideal in acoustically challengingenvironments, or applications where intelligibility-overdistance is required.

The RBN1203 driver is mounted in a co-axial speakerconfiguration 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-ribbontechnology. The acoustic length assists the QRP40 in
an extended vertical projection control in the low-mid
frequency range, at the same time enabling a smoothbut powerful roll-off to additional subwoofers.

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 (90-degrees)
horizontal dispersion offers a consistent audience
coverage up to the highest frequencies.

The frequency response roll-off enables an excellent
partnering with an additional subwoofer, like theQB363.

slim and unobtrusive package; The M10 mounting
points on top and bottom and the M6 universal
mounting bracket pattern on the back, together with theoptional ACO™ color scheme provides for aninconspicuous, low-profile presence in any application.

The QRP40 is powered and controlled by the ALC
amplified loudspeaker controller; Through theintegrated VHIR™ processing, audiophile amplifier
stages and Signal Integrity Sensing™ feedback circuit,
the ALC offers QRP40-specific drive processing,delivering absolute maximum sound quality withincreased headroom and utmost operation reliability
and flexibility.
