Mackie SRM550 12" Powered Loudspeaker High-Definition

The Mackie SRM550 is an active PA speaker featuring a 12" low/mid frequency woofer and 1.4" high frequency compression driver, delivering high-definition audio reproduction through 1600 watts of power. The SRM 550 is the latest addition to the industry leading Mackie range of active PA speakers.

Professional, Raw Performance

The Mackie SRM550 active two way loudspeaker has been designed to deliver incredible audio clarity with serious volume, whilst remaining versatile and hardy to any of the punches life on the road can deliver. A custom 12" woofer provides a tight and precise low/mid frequency response, offering a warm musical tone alongside strong and punchy detail. The SRM550 is equipped with a 1.4" titanium domed compression driver allowing clean and clear high frequency reproduction without compromise. Both speaker drivers have been engineered to withstand extended usage periods, even at the loud gig levels the SRM550 is capable of delivering.

Intuitive Processing

Essential to the high-definition sound of the SRM550 is clever audio system processing. A precision 2-way digital crossover ensures maximum dynamic range for all speaker drivers, with patented acoustic correction (developed in conjunction with EAW) adding to the tight and focused sound. Driver time alignment and phase correction technology means the SRM550 reproduces audio consistently, at any volume level. Smart Protect digital protection is also provided to safeguard both speaker drivers against any spikes or overload from the audio signal. Speaker mode selection makes Mackie's SRM550 even more versatile by changing the overall voicing of the speaker for any situation, be it PA, DJ, or monitoring applications.

2-Channel Mixer

An integrated mixer section adds further to the flexibility of the SRM550, with 2 independent channels providing both microphone and line level inputs - even including a stereo RCA connection for MP3 players or laptops. A one button automatic feedback destroyer is also fitted to quickly eliminate any problem frequencies.

Robust Construction

With an internally braced cabinet constructed from solid poplar plywood the SRM550 is designed to truly stand up to the harsh rigors of the road. A robust steel grill protects both speaker drivers from knocks and impacts. Standard 35mm speaker pole top hats are provided to allow use on stands or speaker poles whilst solidly engineered handles allow easy loading and transport. An angled back design means the SRM550 is as at home as a front of house speaker as it is working as a monitor.
