The W8LS is a dedicated high performance sub-bass system designed to augment the low frequency output of the
W8L in large scale applications where the sub-bass enclosures must be flown. The physical dimensions of the W8LS
are identical to the W8L and it is equipped with the same proprietary rigging system, allowing flown arrays to be
constructed rapidly and safely.
It features twin, 1000 watt 18" (460mm) drive units with magnet structure and suspensions engineered for
maximum linear excursion. The drivers are reflex loaded by ports at either end of the enclosure and substantial
internal bracing is employed to minimise energy absorption by the cabinet walls at the very high pressures generated
within the enclosure itself.
The W8LS is constructed from multi-laminate birch ply and fitted with generously sized handles and a wheelboard
for transportation. To resist ingress of water, the driver cones are treated with a waterproof lacquer and the
perforated steel grille is backed with Declon foam.
The proprietary rigging system of the W8LS is quick to deploy and allows a wide range of W8L array curvatures to
be matched. Intercabinet angles from 0° to 7.5° are set by a rotating splay bar at the rear of the enclosure. All cabinet
rigging hardware is integral and remains captive in transit.
Whilst primarily designed for flown applications, the W8LS may also be ground-stacked on a standard W8L grid,
arrayed and strapped on-end or deployed under the stage apron if required.
W8LS Line Array Subwoofers are designed to be powered by Martin Audio MA4.2s power amplifiers.
