L1 Pro32 with Sub1 and L1 Pro16

- Question
- What benefit will there be adding a Sub2 to an L1 Pro32 with a Sub1
- Answer
- The result will be the same as running the Sub2 alone. The Sub2 plus Sub1 is only slightly louder than the Sub2 alone.
- Testing, testing
- I have an L1 Pro32 with Sub1, and I connected an L1 Pro 16 power stand to the L1 Pro32 line out and then cranked up the volume on everything. I turned the Sub1 off/on and heard almost no difference. The L1 Pro16 drowned out the Sub1. I expect the result would be the same with a Sub1 and a Sub2; the Sub2 would drown out the Sub1.
- The math: If you run a Sub2 and add another Sub2, you can expect up to +6 dB SPL. You get +3 dB from doubling the power and up to +3 dB from acoustic coupling (if the units are stacked or side-by-side). However, if you run a Sub2 and add Sub 1, you might get up to +3 dB SPL, because you are adding less than half as much power and half as much surface area.
- Background
I have two L1 Pro32 with Sub1 systems. I chose the Sub1 option for portability.
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).
Note:
- Sub1 480 Watts RMS into the 7 x 13" racetrack transducer.
- L1 Pro16 1000 Watts RMS into the 10 x 18" transducer.
