- Double-tuned, bass-reflex loaded cardioid-control subwoofer system
- Single 15” woofer with 12” woofer in cardioid arrangement
- Large vents for improved breathing and low port compression
- Low impedance for efficient amplifier loading
- SIS pre-wired for very high damping and further reduced distortion (with ALC)
- Selectable cardioid patterns with up to 42dB rearward rejection
Product description
The BC272 is a self-contained, medium-output cardioid subwoofer system for both permanent and portable ground-stacked applications. It is designed to offer a tight and accurate sub-bass response, for low-frequency extension of any Alcons pro-ribbon system.
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.
