Mackie SR1521Z 2-Way Active Loudspeaker (400 Watts, 1x15 in.)

For those looking to step up from portable active speakers like the SRM450 to the higher output and floor-pounding authority of larger wooden cabinets, Mackie presents the redesigned SR Series. These affordable 2- and 3-way professional active loudspeakers provide large-format sound, real wood cabinets, and integrated "no-hassle" active electronics'retaining all the simplicity of the popular SRM series, but with enough muscle for larger gigs.

Solid Wood Construction
Molded cabinets are perfect for portable loudspeakers like the SRM450, but to achieve the increased output needed for larger gigs, there's still no substitute for good ol' fashioned wood. Mackie's SR Series delivers the renowned simplicity and integrated active electronics of its legendary SRM series, but with higher output 2- and 3-way wooden cabinets. To be specific, the cabinets are constructed of 18mm Baltic birch plywood and pressure-injected structural resin, providing more than enough "knock" to win over any audience.

Integrated Active Electronics
Thanks to completely integrated Mackie Active electronics, the SR Series loudspeakers don't require any external amplifiers, crossovers or processing. The SR Series' internal amplifier modules sit on a mammoth aluminum heatsink that eliminates the need for fans. And the active circuitry inside provides precise electronic crossovers, level protection and time correction. Most importantly, having an integrated system in which the amplifier and all electronics can be "tuned" to specific cabinet designs allowed Mackie loudspeaker engineers to completely maximize the SR Series' output and frequency response.
