Tons o' thump.
The Quik Lok SWA1501 Subwoofer System features a high precision 15" transducer combined with application specific amplifier technology. The system is composed of a single compact subwoofer cabinet with built in control and amplification.
The transducer used in the SWA1501 bass speaker system features a 3", inside/outside wound voice coil that offers extreme power handling capabilities. The magnetic assembly used features advancements in coil venting and structural cooling that provide lower temperatures and substantially improved power compression characteristics.
The amplifier uses a proprietary high efficiency, high current amplifier 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 guitar amplifier is mounted on a large, finned aluminum heat sink, and is rated at 500W RMS continuous output.
The SWA1501 powered subwoofer features a sophisticated onboard control system, allowing for flexible integration with active or passive full range or mid/high speaker systems. The input panel accepts a line level input signal and has loop out connectors for signal routing to other devices. It also has high pass output 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 and also incorporates RMS limiting protection for the amplifier stage that limits the amount of long term power delivered to the transducer.
The cabinet is constructed using 18mm thick birch plywood and finished in black splatter paint. There is one handle on each side for efficient loading and transport as well as a top, female polemount fixture.
