SA1232
The SA1232 is a high-efficiency, extreme-output, active 3-way, wide dispersion, sound reinforcement speaker system. The SA1232 benefits from the integration 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, 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° dispersion 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 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 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, 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 midrange transducer has over 106 dB of sensitivity at
