What should i tune my box too? i have 1 12" Fi Q i was going to go 32hrtz just because that seems to be popular from what I've seen... but since I'm making it this weekend i don't want to make a regrettable decision so any recommendations on what i should do? Fi recommends tuning between 28-33 And also what about box volume does this really effect the sound? if so recommendations? i was going to do 2.5 cubic feet.
