The King Of Subwoofers from Mackie!

The SWA1801z is a high-output active subwoofer system that comes through when you really need bass power! The SWA1801z features a newly designed high-precision 18" transducer combined with application-specific amplifier technology. Even with all this, the SWA1801z is packed into a single compact subwoofer cabinet with built-in control and amplifier electronics.

Mackie SWA1801z Active Subwoofer at a Glance:

• Special design captures the "attack" of low-frequency instruments
  
• Custom-designed transducer with extreme power handling capability
  
• High-efficiency, high-current amplifier for precision reproduction
  
• On-board controls make integrating into your system easy

Special design captures the "attack" of low-frequency instruments
The Mackie SWA1801z does not behave like a typical 18" subwoofer manufactured by 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. With the SWA1801, Mackie 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.

Custom-designed transducer with extreme power handling capability
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.

High-efficiency, high-current amplifier for precision reproduction
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.

On-board controls make integrating into your system easy
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. The SWA1801z 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. The SWA1801z includes 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.

All wrapped up in a 15mm thick multi-layered birch cabinet and finished in black splatter paint, the Mackie SWA1801z is a serious contender for "big daddy" status among subwoofers!
