Axiom SW2100A 21” 2000W Powered Subwoofer

The Axiom SW2100A is a very compact Band-Pass/Bass-Reflex subwoofer providing high output and extended low-frequency response. It is equipped with a single 21” neodymium transducer with a 4” ISV voice coil, large displacement suspension system, and composite reinforced, water-repellent cone, able to provide clean and undistorted LF reproduction at very high SPL.

CORE DSP Platform

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 applications. It features 40bit, 96kHz floating point resolution and top-quality 24bit AD/DA converters, for a perfect signal integrity, dynamic range in excess of 110dB, and superior sonic performance.

SW2100A’s Sophisticated Algorithms

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, managing the protection functions, and monitoring the status of the amplifier.

High-Performance Amplifier

The SW2100A is powered by a DA SERIES digital power module, 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 performance at the top of the range, such as superior sound definition at any audio frequency, very high dynamics for low level signals, and very low distortion even at maximum power.

Superior Sound Quality

The amplifier’s superior sound quality can be compared with top-of-the-range AB-class analog systems, while the DA modules feature higher dynamic range, very compact size, lightweight, and efficiency above 90%. The DA module employed for powering the SW2100A features also PFC (Power Factor Correction), a technology able to guarantee always the highest level of power regardless of any eventual fluctuations of the power supply.

It delivers in an ultra-compact package 2000W from each of its two channels: one channel is used to drive the 21” woofer, the other, through an output SPEAKON connector, can power AX12C line array modules or other AXIOM speakers.

The System

The Axiom SW2100A has been mainly designed to provide the optimal low-frequency extension to the AX12C line array module. The built-in DA power module can provide 2000W to power up to four AX12C line array modules connected to the output SPEAKON. The built-in CORE DSP provides 4 presets for different combinations: 2, 4 or 1 columns plus 1 user preset (additional presets for processing other AXIOM speakers are also available).

The SW2100A features on the top panel a special metal plate and it comes with a dedicated aluminium bracket for fast coupling with the AX12C’s rigging hardware. Using this simple system, up to two AX12C modules can be easily installed on an SW2100A.

The standard system, composed of four AX12C line array modules and two SW2100A subwoofers, features 8000W of total power and a line-array dispersion pattern, making it the perfect solution for high-performance portable sound reinforcement applications.
