Product Description

zZounds is an
authorized Mackie dealer

The new SA1521 truly fulfills the demand for more of everything. More power (500 watts). More transducer (RCF Precision 15 in. LF transducer). More SPL (133dB peak!).

The SA1521 is a truly collaborative effort between Mackie, EAW Engineering and RCF Precision. It's an honest-to-gosh technology breakthrough — an active, full-bandwidth solution with seamlessly integrated power and control, premium transducers and that wonderfully wide dispersion that lets everyone in the audience hear the same thing.

Put the SA1521 up against the most popular 15 in. 2-way systems in the world and what happens? You suddenly discover that the competition is obsolete — problematic in design, poor in definition and basically nothing more than a 15 in. and a 1 in. playing separate tunes.

It doesn't take long to realize that the new SA1521 truly re-defines 2-way 15 in. speaker systems. The SA1521 is an Active speaker system that expands the performance envelope of previous Mackie Active products. It has better resolution, output, and linearity than the SRM450 and higher output than the SR1530 product. It also sets a new standard for 15 in. woofer/1 in. compression driver based systems through its smoothness, power and mid-band performance. This leads to a compact product with a broad range of applications that is powerful and very easy to use.

Design Overview
Mackie's SA1521 is an active 2-way sound reinforcement speaker system designed for extreme accuracy, high output, and smooth dispersion across the entire audio frequency range. It integrates 500 watts of amplifier power, active control electronics, and RCF Precision components into a speaker system with 100 dB sensitivity (1 watt @1 meter). The resulting high resolution and clarity in the critical low-mid and mid-range frequencies are unparalleled for a 15 in. loaded, 2-way speaker system.

Several state of the art advancements in transducer technology have been incorporated in the design of the SA1521. The compression driver uses a new 1.75 in. titanium diaphragm featuring a 3-slot, optimized geometry phase plug. When coupled to the low-distortion, high-output horn, the SA1521 provides uniform power response and correct phase alignment characteristics at the crossover frequency. With the resulting 75 zZounds is an authorized dealer of Mackie products.
