Not sure yet if I already have someone to build my sub box. Wondering if I might need to find someone else.

I got all the modeling graphs and specs from a Focal engineer (their customer service is good, just gotta push a little). They sent the internal dimensions (not external though) and port size and shape. They said to taper the ends of the port like a trumpet.

Anyone good at that kind of work in MA or New England?
