The front-loaded system delivers a super accurate bass and sub response with highest output under lowest distortion, due to the long-stroke 15” woofer. This new-generation transducer is fitted with a large, dual- 3.5” voice-coil Neodymium motor, enabling a significantly-extended excursion*, while maintaining a high sensitivity. Specific attention in this design has been paid to obtain lowest possible distortion. The Max-Vent™ port design combines further increased output with low power compression. *(not included in SPLpeak spec).

Optimal deployment flexibility is guaranteed: The LR15B can be used as single subwoofer or in multiples; As end-fire or cardioid array; Together with LR15 or in separate sub-only arrays. All functionality is possible in stacked or flown configurations. The integrated stand mount adapter provides for easy top/sub combinations with any Alcons pro-ribbon system.

Rated for a high WorkingLoadLimit with 1:10 safety ratio, the versatile rigging system, with front and rear splaying possibility, enables straight or pre-curved flown (cardioid) arrays, to be flown besides or behind an LR15 array.

Array configurations can be simulated through the LR15 GLL in the Alcons Ribbon Calculator (ARC), Alcons’ high-resolution 3D simulation program.

Mobile (cardioid) stacks of up to 3 units can be transported through the PRRGLR15B pre-rig, including stack-specific softcover.

For full system performance, the LR15B is to be driven and controlled by the ALC amplified loudspeaker controller; Driven by the ALC, the LR15B delivers full operation flexibility, maximum sound quality and output power with long-term operation reliability.

The Signal Integrity Sensing™ pre-wiring ensures complete cable/connector compensation between the LR15B and ALC, significantly increasing response accuracy and reducing both linear and non-linear distortion to an absolute minimum, regardless of cable length and system impedance.

By means of a front and rear located woofer configuration, in combination with dedicated processing, the system offers selectable cardioid low-frequency pattern control and excellent rear rejection (up to 42dB), without the need for additional cabinets.

On the front side, one 15” long-excursion woofer with 4-in. voice-coil with double-spider and demodulation ring, is mounted in a front-loaded configuration.

On the rear side, a single 12” long-excursion woofer with 4-in. voice-coil with double-spider, is mounted in a “front”-loaded configuration.

The large bass reflex ports on the front and the rear side enable excellent breathing capacity, increasing overall output while minimising port-compression.

The relatively low-weight, but rigid enclosure is finished in Durotect™ scratch-resistant coating and is fitted with 2 handles for easy logistics and an M20 stand mount flange (road-version).

The BC272 is powered and controlled by the ALC amplified loudspeaker controller. Driven by the ALC, the BC272 delivers maximum sound quality and output power with long-term operation reliability. Through the integrated processor, the ALC offers BC272-specific drive processing with response optimisation, dedicated power and excursion protection, and hybrid filtering.

The preset library contains cardioid settings for maximum rear-/side-ward attenuation.

The 4 ohms system impedance, makes for a very efficient amplifier loading; Thus enabling maximum output from a single, very compact configuration.

Through the SIS™ (Signal Integrity Sensing) circuit, the cable-length and connector resistance between the BC272 and ALC is completely compensated (system damping factor >10.000), for further increased accuracy and controlled cone-travel, resulting in a tighter sub and bass response.

The BC272 is available in road-version and installation (“i”) version, without handles, wheel dolly board and M20 threaded stand mount flange. It is finished in Durotect™ scratch-resistant coating; Through the Architect Color Option™ program, the BC272 can be finished in any RAL™ color.

Two state-of-the-art 18” long-excursion woofers with 5.3-in. voice-coil with vented triple-spider frame, Neodymium motor structure and all-carbon-fibre cone and dust cap are mounted in a direct-radiating configuration, with centrally-located X-Venting™; Taking more than 25% of the baffle surface, this port is designed to maximise the system’s breathing capacity, while minimising port-compression. The excursion capabilities of the 18” design, extends the output by 3.5dB compared to traditional 18” designs (not included in SPLpeak spec).

On the rear side, a single state-of-the-art 18” long-excursion woofer with 5.3-in. voice-coil, Neodymium motor structure and all-carbon-fibre cone and dust cap is mounted in a direct-radiating configuration, with Flank-Venting™ port; This folded port design enables optimal reflex-breathing, under minimal baffle dimensions.

The BC543 in road version is fitted with 12 handles for easy logistics.

The BC543 is powered and controlled by the ALC amplified loudspeaker controller; The ALC offers system-specific drive processing with dedicated optimisation, power and excursion protection, and hybrid filtering.

The preset library contains BC543 settings for sub/bass/punch response curves, as well as different cardioid patterns for maximum rear-/side-ward attenuation.

Through the SIS™ (Signal Integrity Sensing) circuit, the cable-length and connector resistance between the BC543 and ALC is completely compensated (system damping factor >10.000), for further increased accuracy and controlled cone-travel, resulting in a tighter sub and bass response.

On the front side, one 18” long-excursion woofer with 4-in. voice-coil with double-spider and demodulation ring frame, is mounted in a front-loaded configuration, with X-Venting™; This port takes more than 20% of the baffle surface and is designed to maximize the system’s breathing capacity, increasing overall output while minimizing port-compression.

On the rear side, a single 15” long-excursion woofer with 4-in. voice-coil with double-spider and demodulation ring frame, is mounted in a “front”-loaded configuration, with Flank-Venting™ port; This folded port design enables optimal reflex-breathing, under minimal baffle dimensions.

The combination of complex internal panel lay-out and extensive bracing brings a rigid structure with a high enclosure stiffness from a relatively low-weight package. It is finished in Durotect™ scratch-resistant coating and is fitted with 6 handles for easy logistics + stand mount adapter (road-version).
