Wharfedale Pro WLA-121SUB Line-Array Passive Subwoofer 21-Inches SKU# WD-WLA-121SUB
The WLA-121SUB WLA Series 6400W Peak 21" Line-Array Passive Subwoofer from Wharfedale Pro has an aluminium demodulating ring to keep distortion low for better performance and reliable.
The science behind the new WLA-1 Hybrid Curvature Array is intense. With a breath-taking 21" subwoofer, the new WLA-1 system has been engineered by IAG's International R&D team to be highly versatile - making it perfect for touring and fixed installations.
The WLA-121SUB uses a 21" Beyma driver with a 4.0" Quattro voice coil which results in the most extreme, but controllable flying subwoofer in the Wharfedale Pro line up.
The WLA-1 system can easily be configured in 3 different ways. As a sub-top pole mount, as a flown array with the optional Common Fly Frame, or as a Horizontal system with the optional WLA-1 Link hardware. Such versatility allows for users to deploy the system for multiple activities. WLA-1 is a unique Hybrid Curvature Array. The science behind its development has been intense, but this extreme engineering results in an extra-ordinary system with massive lows, consistent coverage and phase coherance.
This subwoofer has 3 different rigging points and an M20 pole mount.
