I have about a dozen of the PA1000 pre-sold, and each one of them is a different set-up. The stereo LD Maui set-up seems to be the most popular, easiest to setup, probably the best at taming problematic rooms...

Plus most of the time you are playing as background or at a reduced volume, conventional speakers usually need to be at a certain volume before they really start to put out their true potential.

the PA1000 speakers sound great, but not for the audience, as for using just 1 LD Maui mono, is ok, but the Korg sounds it's best in stereo, taking advantage of the stereo effects and samples
