So if my box is tuned to 45hz, and im playing 30hz tones all day and start smelling something, its not the coils that stink?The box has absolutely no effect on the coils. If the coils smell you are sending too much power to the sub, regardless of the enclosure. Try setting your gains with a DMM. The only other thing I can think of is if the subs new you might just be smelling the excess glue being burned off, but that shouldn't last for more than a few quick play sessions.
