Active loudspeaker gives you plenty of power and studio-style clarity, even at high volumes. The SRM450v2 provides efficient power: its Class D LF amp provides 300 watts, while a 100-watt amp powers the titanium dome compression driver for high frequencies. You get ultra-low distortion and amazingly full sound from this speaker, which can be pole-mounted or used as a floor monitor wedge. Mackie's active electronic time alignment, phase-correction, and EQ work together with the components to give the SRM450v2 incredible sound.
