There was a time when a powered speaker was nothing more than a power amp strapped to a speaker enclosure. Although effective, this type of system was hardly optimized to reach full potential of the amps or the speakers. The introduction of the SRM450 in 1999 marked a new era for powered loudspeakers: Active electronics. By incorporating a precision crossover, phase alignment and driver time correction, Mackie “Active” loudspeakers were able to get the most out of the power amps and speakers, providing a high-output and highly portable system that was affordable to the average engineer. This technology is found in each and every Mackie powered loudspeaker. HD Series loudspeakers advance “Active” technology through the use of premium DSP algorithms that streamline this processing, resulting in unmatched clarity and system optimization.
