SW121HLA
21” (530mm), Very High Output, Horn-loaded, Powered, CORE Processed, Subwoofer System
The SW121HLA subwoofer is designed to deliver high-quality low frequency reproduction where very high output is a key requirement, together with well defined and deep basses and fast transient response.
The SW121HLA is a high-performance powered subwoofer with a special configuration based on a small cavity behind the speaker and a very compact horn. With this special design and a particular digital processing, the SW121HLA can be used as an infra-sub and it can provide an impressive low-frequency extension and a “punchy” feeling in the upper bass range.
The SW121HLA is equipped with a 21” (533mm) transducer capable of long excursion (up to 70mm peak-to-peak) and controlled by a Double Silicon Spider. The robust copper 135mm (5.3”) voice coil is wounded in four different layers both outside and inside the coil support, then improving the long term thermal capacity of the loudspeaker. Cones are made in cellulose with a special carbon fiber treatment to increase resistance and durability.
SIGNAL PROCESSING and POWER AMPLIFIERS
The system processing is based on the CORE DSP platform designed by the PROEL R&D Laboratories using one of the most advanced SHARC DSP for audio application. It features 40bit, 96kHz floating point resolution and top-quality 24bit AD/DA converters, for a perfect signal integrity, a dynamic range in excess of 110dB and a superior sonic performance. Thanks to its massive processing power, the CORE platform is capable of providing the most sophisticated algorithms for speaker processing, together with remote control and networking capability.
The PRONET control software, working on a solid and reliable CANBUS based network protocol, provides an intuitive interface for the remote control of the whole system, with the possibility of eqing, delaying, increasing the protections and monitoring the status of the amplifier.
The SW121HLA is powered by DA SERIES digital power modules, a new generation of CLASS D power amplifier with digitally-controlled SMPS. The innovative technology used for these amplifiers (including also the use of a variable switching frequency) offers performances at the top of the range, such as a superior sound definition at any audio frequency, very high dynamics also for low level signals and very low distortion even at the maximum power The superior sound quality can be compared with top-of-the-range AB-class analog systems, while the DA modules feature a higher dynamics, very compact size and light weight and efficiency above 90%.
The DA module employed for powering the SW121HLA includes a universal regulated switch mode power supply with PFC (Power Factor Correction) and delivers in an ultra-compact package a maximum power of 4000W.
