highest decibel with smallest woofer

[rv1890]

Is there a listing or does anyone know what is the highest decibel achieved from the smallest woofer?....
In other words....has anybody measured over 110 db with a 6-1/2" woofer....or over 130db with a 10 inch woofer??.....
That sort of stuff.
bring on the ridiculous stuff too...I was searched this thread and learned someone measuring a 6-1/2" @130db in some huge box, but then I heard it was a rumor.....So is there any tried and true approaches. Thanks.

169.8dB from 1 ten inch
174.8 from 2 17 inch

I doubt that in all honesty, 169db is alot of energy and speakers are not that good at converting electrical energy into sound.

I think speakers are efficient enough. Yes almost 170 from 1 10 inch sub .2db off
