After everyone left tonight, I send the left signal to the Compact and the right signal to the original L1. Of course I had to adjust the volumes to match. Sound WAS phenomenal.
It won't make me another nickel, but it's like sitting in a recording studio.
I may get another Compact and reserve the big L1 for situations where I need all that power.
And yes, one L1 will more than adequately handle 300 people.
I played twice at an outdoor car-racing track, up in the grandstand, and the sound covered the entire stadium easily. There were about 400-500 people there. (However there were no cars running-just an award ceremony.)
