The Mackie Thump215XT 15" Active PA Speaker Pair with Speaker Stands is a bundle of two Mackie Thump 215XT speakers with accompanying stands. The Thump215XT is a ground-up redesign of Mackies flagship Thump PA speaker range. It 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 Thump212XT with DSP through their Feedback Eliminator Music Ducking and custom voicing 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.
