High Intensity Funktion-One Bass Performance


F221 delivers physicality with accuracy for truly involving musical experiences.

It is the proven choice for large scale events, with exceptionally high sensitivity and electroacoustic energy efficiency. F221 provides bass power and dynamics for large areas, typically requiring far fewer cabinets and amplifiers than an equivalent direct radiating bass array, resulting in significant reductions in power consumption and CO2 emissions. Equally suited to large mono bass stacks and broadside arrays, both conventional and cardioid. F221 cardioid arrays have up to 30dB rear rejection in optimal configurations. The ideal bass solution for Vero, VX and Evolution systems.
