Alcons Audio LR7 compact PA cabinet

“Non-compressed, 1:1 high-output sound reproduction with intelligibility, projection control and 'throw’ ”: the characteristics that are aimed at by Alcons for their “The Ribbon” pro-ribbon line-arrays.

Now Alcons transplanted these specifications into the new LR7 micro line-array, weighing a mere 8Kg/17,7lb and measuring just 1,5 CD high and 3 CD’s wide; And with Alcons’ patented pro-ribbon technology, as always without “creative horn plumbing”.

The LR7 is a passive 2-way line-source loudspeaker system. It is a true line-array system, to be used as vertical array, either in stacked or flown configuration, for both portable and permanent installations.
The frequency response of 74Hz (-3dB) to beyond 20kHz. enables a full-range deployment without the immediate necessity of additional bass systems.
In applications where extended bass response is required, the LR7 can be combined with a pressure-bass or deep-sub system.

Loaded with the RBN401 pro-ribbon driver on a “Morpher” lens (up to 94% frontal radiation), the system features a 90° or 120° dispersion of choice with seamless coverage, due to the ribbon’s all-natural cylindrical (Isophasic) wavefront. Its transient response and unusual high peak power handling (800W/200mS) caters for intelligibility and throw, while offering maximum “gain-before-feedback” up to directly under the array.
The micro-compact size, combined with the weight-saving all Neodymium drivers, makes the system very easy to handle.

The “Morpher” is mounted in the “ALrad™” waveguide, which utilizes the stiffness and heat transfer capabilities of aluminium. Mounted on the RBN, the ALrad™ extends the cooling surface for even further reducing power-compression for increased SPL over time.

The SignalIntegritySensing™ pre-wiring ensures complete cable/connector compensation between the LR7 and ALC. Typical (short to medium throw) applications for the LR7 include as compact main system for theatre, A/V or corporate events where minimal sightline obstruction is required, with exceptional sound reproduction.

For full system performance, the LR7 is to be used in combination with an ALC amplifier/controller. Driven by the ALC, the LR7 delivers maximum sound quality with inaudible (power and excursion) protection (SDP circuit). The 16 Ohm impedance enables up to 8 cabinets per controller amplifier channel.

The LR7 is part of the The Ribbon Network inventory; Alcons’ global dry-hire network and comes with a 6 years limited warranty.
