Before I get the tomatoes thrown at me and the BOOOOOS please allow me to explain. I am in the process of modifying my cabs and part of that process involves retuning them. I am interested in putting 2 ports in the back and 1 in the front simply for cosmetic reasons. I have never seen this done and I was wondering why? I have done extensive research here and on the web. The issue of front or rear porting has been beaten to death for sure but why not both? Is there a phase issue? Has it simply not been tried or needed before? Please share your thoughts with a budding cabinet maker, whether it be speculative or factual. I enjoy reading all points of view.
