LOL. Let me put it this way. My garage speakers are Polk 10a’s stacked with 7b’s. The eq is a legacy H/K citerion with a pair of 200 watt yamaha amps.
I can deafen the neighbors half a block away if I wanted to.
114 db at max. Above concert level.
(I like my amps to run class A, ie. at the bottom end of their power range, so that is why all the power. Just sounds so much better.)
Way back in my Drum Corps days, the director went around the horn arc with a sound pressure meter, and we each played as loud as we could. I hit 110 dB.
