The One Systems ONE.SL15 is a weather protected, directradiating 15 two-way loudspeaker solution for professional audio applications indoors or for inland uses outdoors. The system’s direct-radiating transducers include a 15 woofer with a 3 voice coil and a compression driver with a 2.5 pure titanium diaphragm coupled to a large rotatable 60° x 40° horn. Itsone-piece rotomolded enclosure is made of UV resistant High-Density Polyethylene (HDPE) with internal steel reinforcements for added strength. The enclosure is ported to enhance its low frequency performance. The ONE.SL15’s input section features an input weather cover with an IP 68-rated gland nut and its barrier strip has stainless steel hardware. The enclosure has 10 x M10 integrated stainless steel rigging points, which can be used in conjunction with the included U-Bracket for mounting to walls or ceilings. An optional pole mount bracket is also available for additional installation flexibility.

The ONE.SL15 provides high vocal intelligibility with wide response capability from its reasonably-sized enclosure. Ist compression driver with pure titanium diaphragm delivers extended response and its long-throw horn is rotatable to facilitate horizontal or vertical placement for added flexibility. The woofer’s specially treated cone and surround provide excellent acoustic damping, moisture resistance and protection against dry rotting. The ONE.SL15’s vented enclosure and premium components provide 126 dB continuous, 132 dB peak output capability with wide frequency response and excellent transients for precise vocals and accurate music reproduction.
