Mackie SWA1801 Powered PA Subwoofer The Mackie SWA1801 is a 900-watt, 18-inch powered sub that features a high precision transducer and onboard active electronics.
Want to add a serious amount of low end kick to your PA? How about an Extremely Serious amount of low end? You need to check out the Mackie SWA1801.
The SWA1801 powered sub features a high precision transducer and onboard active electronics. The SWA1801 is capable of up to 135dB peak output - truly extreme! It also 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 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.
High Resolution Audio Reproduction
The SWA1801 does not behave like a typical 18" subwoofer manufactured by so many other companies. It has been designed using Mackie's belief that live audio subwoofers should focus on the character of the "attack" the device has. They have also focused their energies on the design of double horn loaded chambers to achieve a significant increase in output and lower distortion characteristics which lead to high resolution performance.
RCF Precision, the same company that provides high-tech compression drivers and woofers for high-end touring rigs like EAW's KF760, has developed a new woofer for Mackie's use.

The transducer used in the SWA1801 system features
an RCF Precision 4-inch, inside/outside wound voice
coil that offers extreme power handling capabilities. The
magnetic assembly used features advancements in coil
venting, composite polymide former construction, and
structural cooling that provide lower temperature rise and
substantially improved power compression characteristics.
The amplifier found in the SWA1801 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 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, which is
mounted on a large, finned aluminum heat sink, is rated at
900 watts RMS continuous output.
The cabinet is constructed using 18 mm thick multilayered 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 pole mount fixture.
