as well as doubling cone area
i knew a guy who doubled power (i think...might have just added a lot more power) and said his score actually went down.
from what i understand, every 3 db's is twice as loud (but as said, not to the ears) so you cant just go adding 1000 watts to gain a db, or else there'd be no end to it. i mean...look at the people who run 100,000 watt burp machines. say...if they hit 150 with 5000 watts. they'd only need 20,000 more watts to hit a 170 using his theory. steve himself has 20k watts and hits mid to high 150's, nowhere NEAR a 170. imo...once you get to a certain level, a 158 is nowhere near a 159, or 160 since it will take SO MUCH work and tweaking and power and whatnot to get that next db
