First time post. I'd like to build some ported enclosures for a pair of 123A woofers I have. I was hoping to find the spec sheets JBL put out with their drivers that showed frequency response with specific enclosure and port. I've done some searches here but can only find Theile Perameters for the 123A. Unfortunately, I do not know how to design an enclosure using those perameters. I was wondering if anyone has an enclosure design they are happy with that I could mimic? I read up on the open baffle design but think I'd like to stick with a ported enclosure.

Thanks for any help.
