 The transducer used in the SWA1801z system features a 4-inch, inside/outside wound voice coil that offers extreme power handling capabilities.The magnetic assembly used features advancements in coil venting, composite polyimide former construction and structural cooling that provides lower temperature rise and substantially improved power compression characteristics.
The amplifier module found in the SWA1801z cabinet is an example of application specific amplifier design that can be exercised when designing active speaker systems. The system uses a proprietary high efficiency, high current amplifier module designed to provide high current levels at all levels of operation. Having access to high current levels, no matter what the power output, is absolutely critical in achieving precise, total control of the woofer mass. This control is responsible for lowering audible distortion artifacts and providing aggressive attack through the operating band pass of the system. The amplifier module is mounted on a large, finned aluminum heat sink. The amplifier system is rated at 800 watts RMS of continuous output and 1000 watts peak output.
The SWA1801z features a sophisticated on-board control system allowing for flexible integration with active or passive full range or mid/high speaker systems. The input panel accepts line level input signal and has LOOP OUT connectors for signal routing to other devices. It also has HIGH PASS out connectors for connection to active full range speakers or amplifiers powering passive full range speakers. All signal routing is through XLR connectors in L+R stereo or mono. There is a phase selection switch and a recessed level control. The system features thermal protection for the power supply and amplifier module and also incorporates RMS limiting protection for the amplifier stage that limits the amount of long term power deliver to the transducer.
The cabinet is constructed using 15mm thick multi-layered birch plywood and finished in black splatter paint. There is one handle on each side for efficient loading and transport as well as a female pole mount fixture.
