Wharfedale Pro XLA 221SUB

The Wharfedale Pro XLA-221SUB is the flagship dual 21-inch subwoofer of the XLA line array system, delivering the infrabass that anchors a large-scale rig. It uses two custom 21-inch Beyma drivers with cast aluminium frames, aluminium demodulating rings and Maltcross cooling technology for extreme, controlled output.

Between the drivers sits Wharfedale Pro's Flared Laminar Port, which smooths airflow and all but eliminates the port turbulence and chuffing that muddy bass at high SPL. Serious low end for festivals, arenas and large touring systems.
