The WM4’s more compact cabinet houses a 130 mm (5 in) bass / midrange driver and a Nautilus™ tube-loaded tweeter. As with the other models, the WM4’s corrosion-proof materials and self-draining ‘J port’ resist the elements. And, in line with the WM6, the WM4’s wall bracket allows it to be angled in both vertical and horizontal directions.
