Building on the technology that spawned the highly acclaimed SWA1801, the Mackie SWA2801z features an 800-Watt FR (Fast Recovery) Series amplifier and dual high-precision 18 in. transducers mounted in a custom designed enclosure. The SWA2801z was intentionally over-engineered for both durability and performance by the world-renowned loudspeaker gurus at EAW (Eastern Acoustic Works). Onboard Mackie Active electronics ensure seamless integration of the amplifier and transducer at all times, creating a system that is highly efficient and versatile. This all adds up to a high-output system that'll shake the dust from the rafters!

True Mackie Active Design
Active doesn't just mean the SWA2801z has an amplifier bolted on its back -- it means optimized electronics that provide complete control and maximum performance over all components. The onboard Active system controls the crossover filters, equalization, protection for the transducer and electronics, and provides real time vigilance over the entire system. There is simply no way that you can get this kind of full system functionality by strapping an amp on the back of a passive speaker box.
Crossover Built Right In
Connecting and setting up the SWA2801z couldn't be easier. It accepts a stereo or mono line-level signal via female XLR input jacks. Male XLR Thru jacks are provided for daisy-chaining the signal to additional SWA2801z cabinets. The built-in crossover routes the high frequency content to the high-pass output jacks, which can be used to feed the inputs of full-range Active speakers, such as those in the Mackie SAz Series, or an amplifier powering a pair of passive speakers. A Subwoofer Level control lets you adjust the balance between the subwoofer and the full-range speakers.
800 Watts of Chest Pounding Power
The onboard amplifier, which produces 800-Watts continuous power, sits on a massive heatsink, eliminating the need for fans and dramatically extending life expectancy. A tremendous benefit of having the amplifier inside the subwoofer enclosure is that the SWA2801z functions as a complete system, optimizing acoustic, electronic, and mechanical designs to achieve the highest level of performance and value.
Versatile Placement
The SWA2801z subwoofer is designed to sit on the floor, either upright or on its side. (Feet are provided on the bottom and on one side.) A pole mount cup (socket) is provided on the top and on one side of the SWA2801z for mounting Active loudspeakers such as the Mackie SA1521z, SR1521z, SRM450 or SRM350. Amplified passive systems such as S200, C300z or S408 can also be deployed in this manner. (When pole-mounting loudspeakers on the SWA2801z, please use the Mackie SPM100 and only with recommended models.) Additionally, footholds are embedded in the cabinets top and side that allow for stacking of Mackie's larger Active speakers such as the SA1532z.
Solid Real Wood Construction
For high-output loudspeakers, real wood just sounds better -- and it looks better, too! The SWA2801z enclosure is made of select 15mm Baltic birch plywood and finished in black splatter paint. Carrying handles are integrated into each side for easy loading, and casters are attached to the rear for smooth transport.
