North Hollywood, CA (July 20, 2015)—The El Portal Theatre in t North Hollywood, California recently renovated its audio system, opting for an STX loudspeaker system from Ambisonic Sound Technologies to cover the 360 seats in the house.
Built in 1926, the venue’s parallel concrete walls and lack of significant absorption made it very reverberant, so finding a system with considerable directivity was a priority. The system design started with one array on either side of the stage consisting of an STX6620 and STX4625 line array loudspeaker in each array. The 6620 Articulated Column employs six of the company’s Planar Magnetic Ribbon Driver (PMRD) tweeters that are coaxially-aligned with a proprietary, neodymium magnet-driven 6.25-inch mid-woofer.
Ambisonic Sound Technologies’ Array Optimization System (AOS) software to model the system and seating area indicated that the system needed an additional STX4625 array cabinet to cover the front audience area. A DRM212 woofer cabinet was flown with each array to increase low frequency output and overall system dynamics. The two 12-inch woofers in each cabinet improve the integration between the flown arrays and the two DRM215 subwoofers that are installed under the stage. The DRM215 subwoofers add a total of four (2 each) 15-inch, high-output subwoofer drivers to contribute deep low frequencies at high volumes.
Manager Jay Irwin said, “The sound is amazingly even throughout the house, so that every audience member hears the same exact thing - from the front row to the back row it sounds exactly the same,“ he noted. And not only is it even, he remarked, “The speakers have punch and excitement, but never seem harsh or brittle. They have a wonderfully organic and natural sound.”
