The 4” midrange drivers are compression-loaded to raise efficiency and enter the horn walls via annular slots close to the HF throat to sum effectively with the HF wavefront. In the HF section, four 1” exit compression drivers deliver pristine high frequency sound without the harshness and distortion associated with larger format devices.
The 8” LF drivers are set back behind the walls of the HF horn, with a small volume of air in front of each driver increasing the output at the upper end of its operating range. The LF exit apertures are spaced apart horizontally to provide useful LF horizontal pattern control.
As the company explains, this was a ground up product development. “We wanted to overcome the deficiencies and compromises of other 8” line arrays available on the market today. That’s why we have more drivers in WPS than anything else we believe in its class, with spacing, waveguide and crossover point engineered to deliver in particular optimum HF performance with exemplary mid and high frequency pattern control, even at higher SPL.”
The Wavefront Precision series evolved the technology and innovation of Martin Audio’s landmark MLA series by offering external amplification and scalable resolution. The systems deliver greatly improved coverage, consistency and control compared with standard line arrays, and are uniquely flexible, upgradeable and financially accessible.
“Simply put, the more enclosures with dedicated amplifier channels, the higher the resolution and scale of coverage and control is achievable. This means even at the lowest level of resolution the results are still fundamentally better than traditional line array, at no extra cost, and at the top end of resolution users can enjoy many of the benefits that MLA systems provide. Presently other manufacturers are forcing their customers to buy very expensive and fixed amounts of amps to optimise arrays, but with Wavefront Precision the decision on the level of coverage control, and therefore the number of high-powered efficient iKON amps required, is the customer's.”
Designed to set a new benchmark for 8” line arrays, Martin Audio’s fourth model in the Wavefront Precision line array series, follows the introductions of WPL (12” LF), WPC (10” LF) and WPM (6.5” LF) models. WPS is a versatile solution with a peak SPL of 133dB and perfect for applications that require a high output array with reduced weight and footprint. The flexibility of WPS makes it an ideal system for live sound reinforcement and installations in theatres, concert halls and Houses of Worship. Return-on-investment within a rental company’s inventory is maximised by also deploying WPS arrays as front-fill, delay or side-hang support for larger Wavefront Precision systems.
“We wanted to overcome the deficiencies and compromises of other 8” line arrays available on the market today. That’s why we have more drivers in WPS than anything else we believe in its class, with spacing, waveguide and crossover point engineered to deliver in particular optimum HF performance with exemplary mid and high frequency pattern control, even at higher SPL,” Harter adds.
For extended low frequency performance, WPS is designed to be partnered with the SXC118 cardioid subwoofer and its flyable variant, SXCF118.
“Wavefront Precision has been the company’s fastest ever selling line array series,” recalls Harter, “and a significant contributing factor in Martin Audio’s rapid success over the last three years. The introduction of WPS extends the line to make it an all-powerful optimised line array family that will best serve customers around the world. As one of the founders of the pro audio industry it remains critical that we continue to push forward with our aggressive new product strategy in order to flourish.”
