The One Systems ONESP12D  is a weather protected large format sound reinforcement system. The one piece rotomolded enclosure is made from of a UV resistant high density polyethylene and is ported to aid low frequency extension. The 12″ driver is horn loaded to achieve higher SPL than would otherwise be possible. There are 5 integrated rigging points, which can be used in conjunction with the included U Bracket kit for mounting to walls or ceilings. Two optional Pole Mount Kits are also available. The grille is made from CNC punched steel, and coated in a two-layer zinc rich, UV resistant powder coat finish.

The 12″ woofer uses a treated cone for resistance against water absorption and dry rot. The high energy ferrite magnetics ensure high SPL for maximum coverage. The high frequency driver is mounted in front of the woofer to a large mouthed horn. This allows the compression driver to be crossed over at a lower frequency to maintain full pattern control across the entire frequency spectrum. The large format compression driver in the One Systems ONESP12D is a new design which offers extremely high SPL, avoiding the need for a separate mid band and high frequency compression drivers, and still providing high SPL.

The  ONESP12D is well suited to outdoor environments where a reliable, weatherproof system is specified.
