Mackie SR 1530
A totally unique approach to high-output accuracy

If you shop music stores or browse the web, you'll discover that there aren't a lot of portable three-way sound reinforcement systems. Moreover, there aren't any active three-way systems designed for smaller venues.

We thought that was a shame... since a three-way system can deliver enhanced fidelity and detail to vocals and instruments that fall in the critical midrange frequency spectrum. A three-way system is perfect for everything from hard rock and rap, metal to country, churches, or acoustic groups with vocal ensembles or string and woodwind instruments - anywhere that accuracy and fidelity are important.

So we set out to realize the potential of a three-way PA system by applying our active electronic and amplifier technology, a completely new type of integrated horn system, and some of the world's finest precision transducers.

When we got through, we had a system with audiophile accuracy and output levels that can bleach the tattoos off the loudest thrash band.

Active 15-inch, 2-Way SR Speaker System Mackie SA 1521

The SRM450 re-defined live sound. So much so that a lot of folks have asked for MORE OF EVERYTHING.
The new SA1521 truly fulfills the demand for MORE OF EVERYTHING.MORE power (500 watts). MORE transducer (15-inch LF transducer). MORE SPL (133dB peak!).

The SA1521 is an honest-to-gosh technology breakthrough - an active, full-bandwidth solution with seamlessly integrated power and control, premium transducers and that wonderfully wide dispersion that lets everyone in the audience hear the same thing.

Put the SA1521 up against the most popular 15" two-way systems in the world and what happens? You suddenly discover that the competition is obsolete - problematic in design, poor in definition and basically nothing more than a 15" and a 1" playing separate tunes.

It doesn't take long to realize that the new SA1521 truly RE-DEFINES 2-way 15-inch speaker systems.The SA1521 is an Active speaker system that expands the performance envelope of previous Mackie Active products. It has better resolution, output and linearity than the SRM450 and higher output than the SR1530 product. It also sets a new standard for 15-inch woofer/ 1-inch compression driver based systems through it's smoothness, power and mid-band performance. This leads to a compact product with a broad range of applications that is powerful and very easy to use.

Design Overview
Mackie's SA1521 is an active 2-way sound reinforcement speaker system designed for extreme accuracy, high output, and smooth dispersion across the entire audio frequency range. It integrates 500 watts of amplifier power, active control electronics, and top-quality components into a speaker system with 100 dB sensitivity (1 watt @1 meter). The resulting high resolution and clarity in the critical low-mid and mid-range frequencies are unparalled for a 15" loaded, 2-way speaker system.

Several state of the art advancements in transducer technology have been incorporated in the design of the SA1521. The compression driver uses a new 1.75-inch titanium diaphragm featuring a 3-slot, optimized geometry phase plug. When coupled to the low-distortion, high-output horn, the SA1521 provides uniform power response and correct phase alignment characteristics at the crossover frequency. With the resulting 75°x 65° dispersion pattern,the SA1521 provides very open, natural sound reproduction at extreme output levels.

A 15-inch high-efficiency woofer produces tight, punchy bass. The woofer's magnetic structure delivers an exceptional amount of magnetic force and is responsible for the system's high sensitivity and high efficiency by providing tight control over the cone's movement. This tight control over the woofer's moving mass results in unusually smooth low-frequency response from 50Hz up to the mid-frequency crossover point at 1300Hz.

The amplifier for the compression driver incorporates a Class AB topology, renowned for its clarity, warmth, and high-voltage output to generate extreme SPL levels. A Class G design is used for the low-frequency amplifier, which features two power supplies for improved efficiency and more output power per pound.

A signal panel and a power panel are located on the amplifier assembly at the back of the cabinet, separated by a large aluminum heatsink. The signal input panel contains XLR connectors for line-level input and loop-through connections, a level control, and four status LEDs for Power ON, Signal Present, Limit, and Thermal functions. The power switch and IEC AC connector are located on the lower power panel.

The internal processor provides complete system management of all electronic and acoustic functions. These include an electronic active crossover, electronic phase alignment, electronic time correction, electronic equalization, and complete amplifier and component protection.

To ensure long term reliability,the amplifiers are mounted on a massive extruded heatsink, which is convection cooled and dramatically extends the life expectancy of the heat-producing components.

The SA1521 cabinet is constructed using both multilayered plywood and pressure injected structural resin. The combination provides a robust enclosure with useful ergonomic features. There are three-part cast aluminum handles on each side of the enclosure placed at the speaker's center of gravity for easy carrying and setup. Handles are also located on the top and bottom of the cabinet for easy movement and relocation. A built-in pole-mount cup is provided on the bottom,and a full-size, oval punched, weather-resistant steel grille protects the front of the cabinet.

• The Mackie 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 high precision components into a speaker system with 103dB 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 90º x 40º 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 asan 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 six-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 136dB of acoustic output. This required the design of radically different components from what was used in the SR1530. The SA1232 incorporates several state of the art advancements in transducer technology that have been in development for over two years. The compression driver is a new 1.75-inch titanium diaphragm design featuring a 3-slot, low distortion geometry phase plug. The magnetic structure incorporates pure, high grade, 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.

  Although the six-inch diaphragm from the SR1530 looks similar to that of the SA1232, they are in fact dramatically different. Once again our engineering team developed a new Neodymium magnetic structure 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 1 watt / 1 meter but, more importantly, it also possesses excellent distortion and linearity. This is a fundamental reason why 3-way systems can reproduce mid-band audio signal with higher output, definition and dynamics. The mid-range transducer operates between 700 Hz and 3,000 Hz eliminating the placement of a crossover point in the middle of critical voice frequencies.

  The amplifiers for the compression driver and mid range incorporate a Class AB topology renowned for its clarity, warmth and more importantly the high voltage output required to generate extreme SPL levels.

  The SA1232 produces deep bass through a duo of 12-inch high efficiency woofers. The magnetic structure designed for the woofer motor is greatly responsible for the system's resulting low frequency section sensitivity of 101 dB at 1 watt / 1 meter. High efficiency motors provide an extraordinary amount of force compared to the overall cone area along with complete control of the cone mass. Two 12-inch woofers provide greater air movement than a single 18" woofer but with greater speed, control and better attack. This type of control allow the woofers to deliver extended bass response and to efficiently reach the mid frequency crossover point. The SA1232 frequency response is linear between 45Hz and 18KHz (+/-3dB).
