i am not understanding you? gross im at 2.31cf

* after a **** break i think your saying the subs need 1.75 plus the port correct? if you notice on the right i have the measurements of the box that comes out to 2.31cf, and RE says 1.916(i guess they take the port displacement out) so 1.916 take away the subwoofer displacement im at 1.77cf..... sorry that i misread your post

The re. Box calc is off by 3-5 hertz higher so try tuning it lower and see how that works

Dont use any of them. Use one of us. Thats what we are here for. For my designs being only $20 each, you will get MUCH more than an online calculator.
