V221 is the proven choice for large scale events, with exceptionally high sensitivity and electroacoustic energy efficiency.V221 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. V221 cardioid arrays have up to 30dB rear rejection in optimal configurations.The ideal bass solution for Vero and VX systems.
