										<content:encoded><![CDATA[<p>The BF121 is a high-performance subwoofer system, delivering tight and accurate bass response with very low distortion. It features a single 12” long-excursion woofer, with double-spider suspension and 4” voice-coil in a bass-reflex configuration.</p>
<p>The direct-radiating woofer is mounted in a vented chamber, with large bass reflex port for excellent breathing capacity, increasing overall output while minimising port-compression.</p>
<p>The double baffle board and the combination of complex internal panel lay-out with extensive bracing brings a rigid structure with a high enclosure stiffness from a relatively low-weight package.</p>
<p>For full system performance, the BF121 is driven and controlled by the ALC amplified loudspeaker controller; Driven by the ALC, the BF121 delivers maximum sound quality and output power with long-term operation reliability. The integrated factory presets in the drive processor of the ALC offer gain, phase and filtering matching with all Alcons top systems, including cardioid projection control presets. The additional front-positioned NL4 connector caters for easy “reverse connection” in cardioid arrays.</p>
<p>The 4 ohms system impedance, makes for a very efficient amplifier loading; Thus enabling maximum output from a single, very compact configuration.</p>
<p>The BF121 is SIS™ pre-wired: Through the Signal Integrity Sensing circuit of the ALC, the cable-length and connector resistance between the BF121 and ALC is dynamically compensated (system damping factor 10.000), further reducing distortion, while increasing response accuracy.</p>
<p>The BF121 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 BF121 can be finished in any RAL™ color.</p>
<p>The BF121 packs the same punch and accuracy as its bigger brothers BF151 and BF181 compact subwoofers, and is a perfect companion for the VR5 monitor as super-compact PA system.</p>

										<content:encoded><![CDATA[<p>The BQ211 is a quarter-wave loaded subwoofer system, extending the low frequency response of Alcons’ pro-ribbon systems, in both permanent and portable applications. Featuring a state-of-the-art 21” Neodymium transducer, this subwoofer is designed to offer maximum, prolonged high impact SPL performance from a relative small footprint.</p>
<p>For this, the latest materials and innovations have been applied: A very large displacement transducer with all-carbon fiber cone + dust cap, 5.3” voice-coil with vented triple-spider frame plus optimized low resistance impedance, and port-vented magnet structure to maximally reduce power compression.</p>
<p>The extensively internally-braced cabinet features features double-tuned, high-pressure loading, through a rounded 236mm/9.3” diameter low-tuned bass-reflex vent and a wide, high-tuned quarter wave tunnel. This provides optimised breathing at high SPLs, yet keeping the total system weight to a minimum.</p>
<p>Slider feet on cabinet bottom and side enable stacking of multiple BQ211’s into vertical LF arrays: The additional front-positioned NL4 connector caters for easy “reverse connection” in cardioid arrays.</p>
<p>The BQ211 is driven and controlled by the ALC amplified loudspeaker controller, for maximum sound quality and output power with long-term operation reliability. The integrated factory presets in the drive processor of the ALC offer gain, phase and filtering matching with all Alcons top systems.</p>
<p>The BQ211 is SIS&#x2122; pre-wired: Through the Signal Integrity Sensing circuit of the ALC, the cable-length and connector resistance between the BQ211 and ALC is dynamically compensated (system damping factor 10.000), further reducing distortion, while increasing response accuracy.</p>

<p>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.</p>
<p>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.</p>
<p>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.</p>
<p>The large bass reflex ports on the front and the rear side enable excellent breathing capacity, increasing overall output while minimising port-compression.</p>
<p>The relatively low-weight, but rigid enclosure is finished in Durotect&#x2122; scratch-resistant coating and is fitted with 2 handles for easy logistics and an M20 stand mount flange (road-version).</p>
<p>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.</p>

										<content:encoded><![CDATA[<p>The BC543 is a self-contained, high-output cardioid subwoofer system for both permanent and portable applications. It is designed to offer a very high output, tight and accurate sub-bass response, as low-frequency extension of any Alcons pro-ribbon system.</p>
<p>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.</p>
<p>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&#x2122;; 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 (<em>not included in SPLpeak spec</em>).</p>
<p>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&#x2122; port; This folded port design enables optimal reflex-breathing, under minimal baffle dimensions.</p>
<p>The BC543 in road version is fitted with 12 handles for easy logistics.</p>
<p>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.</p>
<p>The preset library contains BC543 settings for sub/bass/punch response curves, as well as different cardioid patterns for maximum rear-/side-ward attenuation.</p>
<p>Through the SIS&#x2122; (Signal Integrity Sensing) circuit, the cable-length and connector resistance between the BC543 and ALC is completely compensated (system damping factor &gt;10.000), for further increased accuracy and controlled cone-travel, resulting in a tighter sub and bass response.</p>
