cubic foot question

[juniper8]

Hello, I am Building some new speaker cabinets out of 3/4 Baltic Birch and have decided that around 9ft3 internal volumn would suit my needs. if the base had to be 30 inches wide and 19 inches in depth how high would the speaker have to be to reach the 9ft3 number? Thanks any input would be great !

I would think around 27 or 28" tall, but I didn't subtract the thickness of the plywood. You'd need to know if the sides would be mounted on the top of the base or the sides of the base to get an exact height.

33.8X30X19=19266 cu in divided by 1728 (cu in per cu ft) = 11.15 cu ft. The wood must displace over 2 cu ft. Guess so.

That's nice, it takes driver displacement into consideration.
