	I have two L1 Pro16 systems. I chose these because they have the J-shape projection pattern (good for playing on elevated stages) AND the output to the bass transducer is 1000 watts RMS (similar to the Sub2).		I have two L1 Pro16 systems. I chose these because they have the J-shape projection pattern (good for playing on elevated stages) AND the output to the bass transducer is 1000 watts RMS (similar to the Sub2). My plan was to use the L1 Pro16 power stand in place of the Sub2 in situations where I needed more bass than the Sub1 could provide.
