The SP218 is an elegant, Class D-powered sub-low system loaded with two impressive neodymium magnet loudspeaker assemblies. The cabinet is constructed of rigid, 13 layer plywood with multiple internal bracing. Particular attention to weight and handling results in several user benefits. Including the 2500 Watt ultralight CCD amps the SP218 is an impressive featherweight of just above 100kg with no less than 12 ergonomic bar handles to carry it around.
Cabinet dimensions are optimised for international truck size. Ergonomic grip point layout, 8 castor positions, additional corner protection and muliple slide bars all facilitate easy transport. Durability is addressed by a sturdy nano-armor™ coating.
The SP218 will endow any kind of F.O.H. or distributed sound system with a rock solid foundation in the lowest audible octaves. The SALC (Single Audio-logic Level Control) speaker management is a proprietary RMS based gain riding circuit which maintains the tonal balance of the sound as perceived by the human ear. Additionally it protects the SP218 drivers from over excursion or overheating.
To match the desired cabinet dimensions and to obtain maximum efficiency, state-of-the-art computer aided modelling techniques and acoustic calculation programs are used to precisely indicate the manifold reinforcing ribs and port tuning.
