The Mackie SRM450 version 2 delivers live sound that sounds like it should. With the SRM Series Portable Active Loudspeakers, Mackie include the technology to help you focus completely on your performance instead of being distracted by constant EQ and level tweaks.
Many portable loudspeakers produce lows that lack substance but the SRM450 V2 delivers astonishingly deep and defined bass frequencies, outperforming the original SRM450, which was renowned for its ability to deliver real low-down sound. That's thanks to the SRM450 V2's Servo Feedback technology combined with its all-new neodymium woofer and 3-inch voice coil.
The SRM450 V2 employs reliable protection circuitry, a built-in limiter for less distortion at peak levels, and an automatic sliding high pass filter to give you that little bit extra volume when the crowd demands more. Thanks to the advanced technology of its power supply and Class-D amp topology, the SRM450 V2 is greater than 90 percent efficient, so more of the power from your outlet goes straight to the transducer, without the power supply and amp giving off loads of heat. Less heat means better performance, and longer life.
