So Hello everyone, I am new to this forum and I need some advice,
I am upgrading to RF P3D415, only one for now, but it will be more soon :]. So I need an advice in box making, how big should it be for best results ? ( cu. ft ) and what size of port ? At RF site I found that Vb Max is 2.80 cu. ft. but I want to know what you guys think. if anyone could help I would be very happy. At the moment I have two RF 12's and I decided to change them to P3D415 . Please help someone.
Here is some pics of what I have now :
