SA1232
 The SA1232 is a high-efficiency, extreme-output,
active 3-way, wide dispersion, sound reinforcement
speaker system. The SA1232 benefits from the inte-
gration of 1300 watts of amplifier 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, resolu-
tion, 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° disper-
sion that integrates both the mid-range and high-
frequency sections. This allows for the horn loading
of the mid-range transducer and seamless coupling
between the MF and HF sections. The 6-inch mid-
range'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 three-
way designs the mid-frequency horn and the high-
frequency 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 fire 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-efficiency, high-power components.
The SA1232 incorporates several state of the art
advancements in transducer technology. The compres-
sion driver uses a new 1.75-inch titanium diaphragm
design featuring a 3-slot, optimized geometry phase
plug. The magnetic structure incorporates pure, high-
grade, Neodymium providing a higher gauss capabil-
ity, significant 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 mid-
range transducer has over 106 dB of sensitivity at
