anyone know the 1/2 wave theory formula?

[QUOTE="ciaonzo, post: 6485235, member: 607015"] Yep, it's just you. That link is full of other links which then link you to other links. I have no idea what you're trying to do but if you just want to find the corresponding quarter wavelength for a given frequency it's pretty simple. 25Hz is the static frequency. 1130/25 = 45.2 ft wavelength 45.2/.25 = 11.3 ft = quarter wavelength of 25Hz 11.3*12 = 135 inches = quarter wavelength of 25Hz Three quarter wavelength is the same thing as quarter wavelength but with more delay from the support of the rear wave. It also means larger physical size to produce the same result. [/QUOTE]
