| Aquariam hose barometric equalizer?
I read somewhere about a DIY sealed sub that the fellow built and added a length of 1/8" aquarium hose, venting to the outside air. The stated purpose was to equalize the pressure when the weather changed, and after the air in the box heated up from use.
I would assume that a few feet of 1/8" hose coiled up in the cabinet venting to the outside would allow very restricted/slow quantities of air to pass. I wouldn't imagine it would allow enough air to pass so as to change the box to an aperiodic style, but I'm guessing.
The sealed subs I'm building will be .5-.6 cubic feet with a 10" dayton titanic.
Has anyone heard of this, better yet has anyone used this approach, and what were the results?
If there is no actual experience, what are your thoughts?
