Very nice work, but the height to width ratio on that port is too high. May well sound good, but at high power it definitely won't behave as predicted and it is not optimum.
You may be right but as of now the current owner is right around 1000rms on the xxx....even though its underpowered it sounds very clean and as long as hes happy thats all that matters
Btw... Box is about 2.3 cubed each port opening is 1x14
Good looking box man!!!
