Try this:

Av = 27"

Lv = 25.5"

Vb= 2.03 cu ft

Using a regular calculator here, and was wondering how do you solve this formula? I am getting numbers that are so random. thank you.

Fb = 0.159*SQRT((27*(1.84*10^8))/((2.03*1728)*(25.5+(0.823*SQRT(27)))))

Fb = 0.159*Sqrt((4968000000)/(3507.84*29.7764334))

Fb = 0.159*sqrt((4968000000)/(104450.964))

Fb = 0.159*sqrt(47562.99)

Fb = 0.159 * 218.089408

Fb = 34.68hz

Remember that Vb has to be in cubic inches, not cubic feet.

bottom part in linear form, Sqrt of 27 *.823 + 25.5 * 2.03

(assuming your measurments are in the correct form inches/feet)

top number dividedy by the bottom number, SQRT that then multiply by .159

or use an online calc.

edit////squeak is good.
