The One System ONESP8 is a weather protected medium format sound reinforcement system. The one piece rotomolded enclosure is constructed from UV resistant polyethylene and features a 35mm pole mount socket to mount of top of a standard speaker pole. The enclosure is ported to aid low frequency extension, and the 8″ 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. When pole mounting is required, an optional Pole Mount Kit can be purchased. The grill is made from CNC punched steel and coated in a two-layer zinc rich, UV resistant powder coat finish.

The 8″ woofer uses a treated cone paper pulp for resistance against water and dry rot. The high energy ferrite magnetics ensure high SPL for maximum coverage from a small system. 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 One System ONESP8 is well suited to outdoor environments where a reliable, weatherproof system is specified. The line matching transformer allows connection to a high voltage line to minimize cable losses over long cable runs, further improving the usability of the system.
