Active 3-way sound reinforcement speaker system.

The SA1232 is a high-effi ciency, extreme-output,
active 3-way, wide dispersion, sound reinforcement
speaker system. The SA1232 benefi ts from the inte-
gration of 1300 watts of amplifi er power, complete
active control electronics, and RCF Precision compo-
nents 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 reproduc-
tion previously available only from high end, esoteric
PA speaker systems.
The SA1232 features the same horn assembly as
introduced in the Mackie Designs SR1530 active 3-way
speaker. The horn is a one-piece design with 90° x 40°
dispersion 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 fi 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-effi ciency, 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, signifi cant 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.
The RCF Precision engineering team developed a
new Neodymium magnetic structure for the 6-inch
mid-frequency driver that provides the control and
effi ciency required to keep up with the compression
driver. By itself, the mid-range transducer has over
