The Mackie Thump215 15" Active PA Speaker is a ground-up redesign of Mackies flagship Thump PA speaker range. The Thump215 provides a brand-new 1400 W Class D amplifier offering improved clarity and power over past models. Revised drivers provide even higher sound output with a maximum output of 129 dB SPL and extended frequency response with better treble. Mackie have also loaded the Thump215 with DSP through their Feedback Eliminator and Music Ducking modes ensuring your show runs exactly as you need it to. Broad connectivity helps make this speaker easy to fit into any setup with two combo XLR/TRS inputs as well as a stereo 1/8" input of channel 2 and a through output for setting up stereo pairs or subwoofers.
