The JBL HLA 4895 3-way combined with the 4897 bass module are JBLs top of the line tour sound products, they are capable of producing 140dB from 34Hz on up from 1 meter....can a pair of these fill up a football stadium with sound? The reason I ask is that my current set-up can produce around 100dB from one meter so they are only 40dBs away from being able to fill up a football stadium with sound?
Basically what I have now is not loud enough for me, but I am pretty close , it seems to me that if I could turn up my volume knob just a couple of notches more I would be satisfied, certainly the Four Pis I am preparing to build should get me there.
So how does SPL perception work, is it that once you get to a certain point each decible becomes more powerful?..In other words does the sound seem twice as loud for each additional decibal after a certain point? How does this work?
