Mackie recently unveiled its new line of Super-Active (SA) P.A. speakers, which are based on SA Series’ designs and feature maximized power, recalibrated active electronics, high-definition neodymium drivers and extensive acoustic design and tuning by Eastern Acoustic Work’s engineering team.
The SA Series speakers will begin shipping to Mackie dealers in Q2, 2005. All four of the new SA Series loudspeakers offer maximum power: 500 watts for the SA1521z ($1,199 MSRP),to 1,300 watts for the SA1530z ($1,699), SA1232z ($1,999) and SA1532z ($2,199). The recalibrated active electronics, which include precision crossovers, level protection and electronic time correction, work in concert with new neodymium mid- and high-frequency drivers to deliver greater accuracy, increased output and reduced weight. To ensure maximum structural rigidity, all SA Series speakers feature robust cabinets constructed from 18mm Baltic birch plywood and pressure-injected structural resin.
“Our goal, quite simply, was to make the new SA Series the best-performing and best-sounding active loudspeakers in Mackie’s history,” commented product manager John Boudreau. “In this effort, we were able to leverage all of the design and engineering talents in the LOUD Technologies family. From the Mackie engineering team to the EAW engineering team, they all applied their specific areas of expertise in the development of these loudspeakers. As a result, I believe that we not only accomplished our goal, but have developed some of the finest active loudspeakers on the market today.”
All three models feature an optimized wide-dispersion WaveFront TM horn design—a one-piece 90×40-degree horn that combines both mid- and high-frequency drivers. Unlike typical mid/high horn designs, the high-frequency section fires slightly downward into the 6-inch midrange driver’s dispersion pattern, creating a focused, single wave front with improved phase and power response. The resulting 90×40-degree dispersion pattern provides open, natural sound for the entire audience, even at extreme output levels.
Frequency response and output differ between the three-way SA Series models, depending on woofer configuration. The SA1530z (one 15-inch woofer) delivers a peak SPL of 135 dB @ 1 kHz/one meter and a frequency response of 38 to 20k Hz. The SA1232z (two 12-inch woofers) delivers a peak SPL of 136 dB @ 1 kHz/one meter, 39 to 20k Hz. The largest model, the SA1532z (two 15-inch woofers), delivers a peak SPL of 139 dB @ 1 kHz/one meter and a frequency response of 38 to 20k Hz.
