L1 Pro32 with Sub1 and L1 Pro16: Difference between revisions

Line 16:

;Testing, testing

: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.
