i built this bandpass just for kicks. it was hitting 135 db with a jl audio 10w3 v-2 sub. car audio in home theater, why the hell not. turns out the bass was to loud for my home theater. i still have crapy rca home theater speakers. had to go with an rca 10 inch sub. still hits loud. havent measured for db yet.
