Used with EVF full-range and low-frequency systems, it extends low-frequency output down to 35 Hz (-3 dB). The EVF-1181S has no internal low-pass filter and runs in biamp mode, with the crossover set in an external DSP. It shares the height of the EVF 12 in and 15 in enclosures, and its rigging lets it form vertical or horizontal clusters with EVF and EVH loudspeakers. The cabinet comes in black or white, in three versions: EVCoat for interior use, PI for indirect weather exposure such as under a roof overhang, and FG with a fiberglass finish for direct exposure.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWoofer:\u003c\/strong\u003e EVS18SB 18 in (457 mm) woofer, developed with FEA optimization of the motor, suspension and electrical design for low distortion at high SPL.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-frequency extension:\u003c\/strong\u003e 35 Hz - 100 Hz (-3 dB, half space).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e 99 dB sensitivity and 131 dB calculated maximum SPL.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower handling:\u003c\/strong\u003e 400 W continuous, 800 W program, 1600 W peak.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput panel:\u003c\/strong\u003e two 4-pin Phoenix\/Euroblock screw terminals that accept up to 10 AWG wire, with optional CDNL4 (dual Speakon NL4), CSG (single gland nut) and CDG (dual gland nut) covers.
