Behringer VP1220D - 12 "/ 1.75" 450W 2-WAY ACTIVE SPEAKER

(This text is machine translated) Instead of operating relatively continuously as in Class AB circuits, Class D amplifiers turn on and off thousands of times per second, delivering power only when needed. In other words, the amplifier is either completely on or completely off, which significantly reduces power losses emitted as heat by the devices. Less heat means these amps don't need heat sinks, meaning they are lighter in weight. The uncompromising Behringer design means that your EUROLIVE D-Series speakers will deliver maximum power with incredible fidelity all night long, without the need for long rest cycles.
