Mackie – SRM450v3 1,000-Watt High-Definition Portable Powered Loudspeaker on May 8, 2017 This is the second redesign of the popular SRM450. The version 3 iteration of this sound reinforcement industry standard offers numerous features unavailable on previous models. It is a 1,000-watt powered enclosure with a 12" LF driver and a 1.4" HF compression driver, a precision two-way crossover and some output processing that you will really appreciate. The SRM340v3 has a "built-like-a-tank" chassis that is cut in such a way that it is also an excellent wedge floor monitor. Not only that, there is a voicing select switch that when engaged for monitor use, adds greater upper end clarity for vocal intelligibility and an enhanced feedback rejection. When using the SRM450v3 in a DJ context, the Speaker Mode switch adds just the perfect low end bump. It likewise has a setting optimized for solo entertainers.
