Thanks for the port dimensions...i used to have a web site where you can input your measurements, and it would calculate your box for you and would give you a colour template on what cuts you need to make and what sizes? this was for a vented box. Does anyone know what that site was? i lost it last time i formatted. Bassically im just unsure of how to cut the inside port walls and to what sizes thats all...if i decide to change the internal size of the box, bracing etc.

Thanks,
Kyle.
