Mackie SA1521 Brochure

The SRM450 re-defined live sound.
So much so that a lot of folks have asked for
MORE OF EVERYTHING.
The new SA1521 truly fullfills the demand for
MORE OF EVERYTHING. MORE power (500 watts).
MORE transducer (RCF Precision 15-inch LF transducer).
MORE SPLS (133dB peak!).
The SA1521 is a truly collaborative effort between Mackie,
EAW and RCF Precision. It's a 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" two-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discover that the competition is obsolete — problematic in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" and a 1" playing separate tunes.
It doesn't take long to realize that the new SA1521 truly
RE-DEFINES 2-way 15-inch speaker systems.
