HD1531 3-Way High-Definition Powered Loudspeaker - Elevate Your Experience

The HD1531 incorporates the latest in Class-D amplifier technology to deliver a chest-pounding 1800W of peak system power. All three internal amps are designed using Mackie's legendary Fast Recovery circuitry. Other amplifiers can ¡°latch¡± when pushed to clipping, leading to distorted audio, but Fast Recovery¢â amplification reacts instantly to the occasional aggressive transient, drastically reducing the time it takes for the amp to recover, ensuring clean audio under the most demanding of situations.

This potent tri-amplified system is the highest powered 3-way available in its class, providing a beefy 700W RMS low-frequency amplifier, a 100W mid-frequency amp and a 100W RMS high-frequency amplifier that, when combined, can deliver a max SPL up to 135dB (calculated, measured maximum SPL of 126dB). There is a lot of debate regarding SPL measurements, and what you see on paper doesn't always tell the whole story.

Even the most expensive loudspeakers on the market have inherent sonic issues that arise from the very nature of loudspeaker design. Horn-loaded drivers tend to have a honkiness to them and there are physical resonances in the upper range of cone drivers that can sound nasty.

Introducing Mackie High-Definition Audio Processing. The key to high-definition live sound is the detailed measurement and analysis of the inherent problems of horns and woofers. After that, the creation and application of some seriously NASA-esque (and patented) acoustic correction algorithms work to correct these very issues. The resulting experience is not only high-definition, it is truly a moment of clarity for anyone within earshot.

The HD1531 is a perfectly tuned system that is truly greater than the sum of its parts. This is only possible due to the hard work and insane genius of the engineering team over at Eastern Acoustic Works (EAW). Not only did they fine tune the system for complete optimization, they also custom-designed the transducers, ensuring maximum efficiency and performance.

The high-end 15" neodymium woofer features a 3" voice coil and is built to handle the massive power delivered by the low-frequency amplifier. The magnet is made using neodymium, which provides a greater magnetic field with far less material. This makes the woofer extremely lightweight without sacrificing one bit of performance. And the large 3¡È voice-coil is built to handle and dissipate far more heat than traditional designs.

A 6¡È mid-range driver takes care of all the mids, leaving the woofer to do what it does best. The 1.75" compression driver brilliantly reproduces high-frequencies with a diaphragm made using heat-treated titanium. Heat-treating increases the rigidity of the diaphragm, eliminating nasty distortion that can occur due to inconsistencies on its surface. It also greatly increases the life of the driver, so you can count on stunning high-frequency production for years.
