TTS28 WP Weatherproof Passive High Power Subwoofer

RCF TTS28 WP is a direct radiating, high output subwoofer system that delivers high-efficiency.

The driver mounting maximizes the cone area and minimizes the frontal area, providing acoustical performance and configuration options well suited for large subwoofer arrays. The newly developed neo drivers ensure the highest output and best sonic performance is achieved for a speaker of this form factor.

Connections to the amplifier are made through a watertight multi-pole connector and the grill is custom perforated aluminium utilising open-cell fibres and water repellent woven fabric backing. The cabinet is constructed of multi-ply Baltic birch plywood and finished in an extremely resistant, textured, Polyurea black coating.
