Antiknock introduces Martin Audio Torus system

Antiknock, a punk/hardcore music club situated in the Shinjuku district of Tokyo, has become the first venue in Japan to install Martin Audio’s new Torus constant curvature array. Speaking of the installation, Mr. Sekikawa, CEO of Hardaway Corporation, which manages the venue, says the renewal of the sound system was a gift to the many artists and patrons who volunteered to sell T-shirts and make donations to keep the venue alive during the COVID pandemic.

The system previously installed featured old long-throw cabinets. Their disproportionate size not only made the stage look small, but the clarity of the low end during live performances left much to be desired. When seeking a replacement system, there were several key criteria that needed to be met: these included being suitable for multi-genres, with a reasonable size footprint, and offering good stability.

Mr. Hashimoto, CEO of Enter Sandman, who designed the new system, explains the rationale: “Having had a relationship with Antiknock for ten years, I was able to determine several important factors. One was the theme of the venue, bearing in mind the type of bands who perform there. Another was the physical shape of the venue and the construction of the building, as well as the size of the loudspeakers. And finally, of course, there was the capability of the loudspeaker itself.” As a result, he specified a pair of T1215 onto two SXCF118 subwoofers per side, in a simple ground stacked configuration.

One challenge was the siting of the PA itself. Since sight lines on the audience floor are obscured by columns and joists, and the floor level increases at the rear, the loudspeakers needed to be set inside the stage area. Torus can be flown from the T12Grid inverted, to allow stereo arrays to be mirrored with the high frequency horn either to the left or the right.

During the initial simulations, Martin Audio’s Display3 3D prediction software was used to great extent by Hashimoto. “Torus has a feature in that we could change the waveguide’s dispersion between 30-45 degrees”, he explains. “We could also change the dispersion, setting the horn asymmetrically to avoid unnecessary reflections from the wall.”

“Antiknock is the venue where loud rock bands choose to perform, and this is reflected in the high SPL”, adds Mr. Kunii, the venue’s operator. “However, the sound from the new system is always clear and transparent.”
