An amplifier was needed for rehearsals and street performances. Thanks to the DSP, one amplifier replaced a large rack of old equipment (crossover, equalizer, limiter, and related cables), reduced potential switching errors for beginners. I made myself presets for working with a mono portal sub + top, or sub in the bridge, or simple stereo. Yes, the numbers of cosmic power can be confusing, but it gives the declared RMS very well.
