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.
