Description

Flightcase: not included Accessories: none The SP218 is a lightweight, Class D-powered subwoofer system designed to deliver powerful low-frequency performance. It incorporates two high-performance loudspeaker drivers with neodymium magnets. The enclosure is made from strong 13-layer plywood and reinforced with multiple internal bracing elements. Despite its substantial output, the system weighs only slightly over 100 kg, including the integrated 2500 W ultra-lightweight CCD amplifiers. Handling is made easier by 12 ergonomically positioned bar handles. Its cabinet dimensions are adapted to standard international truck transport. Eight possible caster positions, reinforced corners, multiple slide rails and carefully arranged grip points support convenient movement and loading. A durable nano-armor™ surface coating provides additional protection during regular use and transportation. The SP218 adds a solid low-frequency foundation to virtually any front-of-house or distributed sound system, reaching into the lowest audible octaves. Its proprietary SALC (Single Audio-logic Level Control) management system uses RMS-based gain riding to preserve the tonal balance as perceived by the human ear. It also helps protect the drivers against excessive excursion and overheating. Computer-aided modelling and advanced acoustic calculation software were used to determine the precise placement of the internal reinforcing ribs and optimise the port tuning. This approach allows the enclosure dimensions to remain practical while maintaining high acoustic efficiency. https://www.salesall.eu/nl/used-sound-projects-sub-series-sp218
