I use two Line 6 L3M's in stereo on stands. They are a 3â€way, triâ€amped speaker system. For smaller venues they can fill the out the direct feed to the PA, for large venues I use one for side fill and one in front of the Helix in a monitor configuration. They not only reproduce the models faithfully, but the Helix can switch speaker programs in the L3M's that are saved with the patches. Very transparent and each L3m can produce 1400 watts.
