Dedicated high performance sub-bass system
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.
FEATURES
Dual long excursion 18" (460mm) direct radiator design
High power - 138dB continuous, 144dB peak (single unit half-space)
Extended response 32Hz – 180Hz ±3dB
Useable response to 28Hz (-10dB)
Compatible with W8L Line Array
Fast, integral rigging system with variable splay angles
from 0 to 7.5s to match W8L column curvatures
Standard W8L grid may be used for flying or ground stacking
APPLICATIONS
Dedicated flown sub-bass for W8L Line Array
Ground stacked sub-bass for W8L Line Array
Under-stage sub-bass
Special effects sub-bass
