: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.

:I have an L1 Pro32 with Sub1, but not a Sub2. Instead, I connected an L1 Pro 16 power stand to the L1 Pro32 line out to simulate adding a Sub2. Then I 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.

: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 by doubling of acoustic volume, cone area and close coupling between the speakers.

::However, if you run a Sub2 and add a Sub1, you ''''might get up to'''' +3 dB SPL, because you are adding less than half as much power and half as much surface area. I expect the gain is less than that.

If running two L1 Pro32 with Sub1 systems and wanted to add more bass, I would do one of the following.

* Put two Sub1 in cardioid mode on one L1 Pro32

* Use the L1 Pro16 power stand for the sub for the other L1 Pro32

OR

* Use the two L1 Pro32 systems behind the performers (assuming there are only two)

** If there is excessive bass build-up on the stage, I would put the two Sub1s together in cardioid mode

* Use the two L1 Pro16 systems (complete with the cylindrical radiators) as extension speakers

OR

* Use all four L1 Pro systems behind the performers (assuming there are four)

* Use the L1 Pro32 for the lead voice/guitars

* Use the L1 Pro16 for the drummer and bass player

Note:

*Sub1 480 Watts RMS into the 7 x 13" racetrack transducer.

*L1 Pro16 1000 Watts RMS into the 10 x 18" transducer.

*L1 Pro16 1000 Watts RMS into the 10 x 18" racetrack transducer.
