The radical Synergy™ Summation Aperture Horn Technology provides remarkably even high / mid frequency distribution from the 60º x 60º horn assembly, delivering unmatched clarity and definition from a loudspeaker box.

Synergy Technology, designed by Tom Danley and engineered into the S4P by VTC Pro Audio is capable of delivering ultra clear reproduction through the high-mid band with extremely linear frequency response. The Synergy horn combines a single 1-inch throat with a 1.75-inch diaphragm high frequency compression driver alongside three 5-inch ceramic magnet midrange drivers on a single, highly efficient conical horn. This combines high and mid frequency energy in a single conical horn that evenly produces frequencies from 350Hz to 20kHz.

The radical nature of the Synergy horn required a radical power amp solution to ensure optimum performance from the system. An integrated DSP provides three-way internal crossover, time alignment, component protection, limiting and an extremely accurate overall cabinet EQ. Time delayed output for accurate subwoofer alignment ensures the VTC S4P delivers maximum impact in systems where complex external processing isn’t the preferred set-up solution.

The S4P uses a combination of amplifier topographies to ensure reliability and superior loudspeaker performance. Two Class A/B amplifier modules deliver 150-watts each to the 1.75-inch horn driver, and to the three 5-inch ceramic drivers that make up the Unity horn assembly. An additional three-tier designed amplifier module delivers 600-watts to the 15-inch neodymium woofer.

The S4P is built using 5/8-inch birch plywood cabinet construction. Integrated bar handles and standmount adaptor allows the S4P to be quickly and easily integrated into any mobile live PA system. The cabinet’s unmatched clarity and performance make an ideal choice as a repeater cabinet in large rooms and concert halls. Integrated flypoints allow the S4P to be flown in multi-cabinet arrays or installations without modification to the box. The cabinet’s trapezoidal shape was designed with tight-pack box arrays in mind.
