SA1232
The SA1232 is a high-efciency, extreme-output,
active 3-way, wide dispersion, sound reinforcement
speaker system. The SA1232 benets from the integration of 1300 watts of amplier power, complete
active control electronics, and precision components
into a speaker system with 103 dB of sensitivity (1 watt/
1 meter). The result is unprecedented output, resolution, and clarity as well as mid-range reproduction
previously available only from high end, esoteric PA
speaker systems.
The SA1232 features the same horn assembly as
introduced in the Mackie SR1530 active 3-way speaker.
The horn is a one-piece design with 90° x 40°
sion that integrates both the mid-range and highfrequency sections. This allows for the horn loading
of the mid-range transducer and seamless coupling
between the MF and HF sections. The 6-inch midrange’s basket assembly is designed as part of the
horn assembly and is also designed to function as
an optimized compression chamber, dramatically
simplifying the mid-range assembly. Also, in threeway designs the mid-frequency horn and the highfrequency horn are physically pointing to a different
location in front of the box. The SA1232 features an
“Optimized Wavefront” horn design. Unlike typical mid/
high horns, the high-frequency section is positioned
to re down into the 6-inch mid-range’s dispersion
pattern. This creates a focused, single wave front with
excellent phase and power response characteristics.
The SA1232 Mid/High Section is designed to
deliver over 136 dB of acoustic output. This required
designing high-efciency, high-power components.
The SA1232 incorporates several state of the art
advancements in transducer technology. The compression driver uses a new 1.75-inch titanium diaphragm
design featuring a 3-slot, optimized geometry phase
plug. The magnetic structure incorporates pure, highgrade, Neodymium providing a higher gauss capability, signicant weight reduction, and higher BL (force)
in the magnetic gap. This results in higher control of
the moving mass, and audio reproduction with lower
distortion and distortion artifacts.
A new Neodymium magnetic structure was
developed for the 6-inch mid-frequency driver that
provides the control and efficiency required to keep
up with the compression driver. By itself, the midrange transducer has over 106 dB of sensitivity at
