The SW1800AV2 is a compact powered manifolded subwoofer designed to provide sub-bass support for the compact AX800A and AX800ANEO compact line arrays, and features some of the most advanced technologies for low frequency reproduction. The manifolded bandpass design uses manifold loading of the front side of the speaker cones to maximize the mutual coupling between the two drivers. This innovative configuration does not use any large resonant cavity to load the speakers, but very compact cavities in order to obtain advantages in terms of definition, both at the lowest end and the upper bass.
SW1800AV2 represents the evolution of SW1800A, with which it maintains full electroacoustic and mechanical compatibility.
The SW1800AV2 subwoofer system is equipped with two high power 18” (460mm) transducers with 3” voice coils wound on aluminium formers for good heat dissipation.
The speaker cones feature a humidity resistant treatment which makes the SW1800AV2 very suitable for outdoor concert touring applications.
The SW1800AV2 represents an innovative subwoofer design that features solid low frequency definition and a “punchy” feeling in the upper bass range. The combination of accuracy in acoustic transient response together with the use of the latest technology in transducer linearity, signal processing, and power amplifiers allows the SW1800AV2 to deliver unprecedented low frequency reproduction quality with solid deep end, together with very fast and accurate bass response. It is designed to complement the AX800A and AX800ANEO line arrays in an approximate 4:1 ratio.
The 15mm birch plywood enclosure features two 35mm pole mount sockets, one on the top and one on the side, allowing satellite speakers such as AX800A/AX800ANEO compact line array elements or any ED series point source loudspeakers to be securely pole mounted on top of the subwoofer at an optimum height for best audience coverage.
Heavy duty wheels and flush handles are provided for easy transportation and handling, while matching stacking recesses and feet enable stable ground stacks to be assembled.
The system processing is based on the CORE2 DSP platform designed by the PROEL R&D Laboratories using one of the most advanced SHARC DSP devices available for audio applications. It features 40bit floating point resolution and top-quality 24-bit AD/DA converters for perfect signal integrity, dynamic range in excess of 110dB, and superior sonic performance. Thanks to its massive processing power, the CORE2 platform is capable of providing the most sophisticated algorithms for speaker processing, together with comprehensive remote control and networking capabilities.
The PRONET AX control software, working on a solid and reliable CANBUS based network protocol, provides an intuitive interface for the remote control of the whole audio system via the rear panel etherCON RJ45 connectors, with the possibility to equalise and delay individual devices, as well as setting driver protection parameters, and monitoring the status of the amplifier.
Four factory DSP presets are provided for when the SW1800AV2 subwoofer is not connected to a network, and allow for rapid and simple setup: Standard, for general purpose use; Infra Sub, as an additional very low frequency band or for sub-bass effects; Cardioid, for use in directional bass arrays; and User, allowing custom parameters to be designed in PRONET and recalled for specific situations when off-line.
The SW1800AV2 is powered by a new generation of CLASS D power amplifiers with digitally-controlled SMPS and latest generation single-stage PFC. The innovative technology used for these amplifiers 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 SW1800AV2 power modules feature a higher dynamics, very compact size and light weight and efficiency above 90%.
The power module employed for powering the SW1800AV2 delivers in an ultra-compact package a total power of 2800W, 1400W for each of the two woofers. Such a large reserve of power means that the amplifier can handle very high voltage peaks, resulting in an impressive dynamic performance.
