Re: Dual 18" Separate Chambers ??Brandon,Half the volume and half the port area will give you nearly the same tuning frequency, but in practice the port tuning function is slightly nonlinear, so a large box with two ports will be tuned slightly lower than the half box with one port.What are you trying to do exactly? The articles I wrote for October's and November's issues of FOH cover a broad swath of the issues related to vented boxes. I suggest you look at them.
