Which is the expected SPL of two combined speakers versus one single?
If I have one single speaker at, for example, 80 dB/m for 100 watts and I add another equal it will add power and produces 86 dB combined SPL?
Or power addition is random and will be (100^2 + 100^2)^1/2 = 140 watts => around 102-103 dB?
