The SW215A subwoofer is designed to deliver high quality low frequency reproduction where very high output is a key requirement, together with well defined deep bass response and fast transient response. Its compact size and light weight make it suitable for several different uses, ranging from touring applications to fixed installations and high-level dance clubs.
The SW215A is a very high quality powered subwoofer system featuring some of the most advanced technologies for low frequency reproduction. Its unique and innovative design is based on a configuration that can be defined as Manifolded Band Pass. It uses manifolding of the front side of the cones to maximize the mutual coupling between the two drivers. This innovative configuration does not use any large resonant cavity to load the speaker, but very compact cavities in order to obtain advantages in terms of definition, both at the lowest end and the upper bass.
The SW215A subwoofer system is equipped with two high power 15” (380mm) transducers capable of long excursion (up to 33mm peak-to-peak), controlled by high stiffness Double Silicon Spider as centering suspension and by heavy duty surround. The motor structure features high strength (BL²/Re) with optimized symmetry and excursion controlled by Aluminum Demodulating Ring.
The robust copper 75mm (3”) voice coil is wounded in two different layers both outside and inside the coil support, then doubling the coil surface exposed to air cooling and consequently improving the long term thermal capacity of the loudspeaker.
Cones are made of very high-stiffness reinforced paper, featuring also invisible water repellent treatment.
The SW215A represents an innovative subwoofer design that features unprecedented performances in terms of low frequency definition and “punchy” feeling in the upper bass range. The combination of accuracy in acoustic transient response together with the use of latest technology in transducers linearity, signal processing and power amplifiers allows the SW215A to deliver unprecedented low frequency reproduction quality with solid deep end, together with very fast and accurate bass response.
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 SW215A 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 SW215A delivers in an ultra-compact package a maximum power of 2000W.
The SW215A is available in two versions, with (code SW215AF) or without (code SW215A) the flying hardware. In the SW215AF model the built-in suspension system allows one or more sub-woofers to be flown together with the AX2065 vertical array module. The flying system is extremely simple to use and a complete array can be flown in a flash by just a couple of people. The SW215A offers a cost effective solution for all applications where flying the sub-woofers in not needed.
