I am looking for a box for a 15 or 18 DCON/XCON. What is keeping me from buying is shipping. I would buy one DIY box today if I like the style. Send me some examples, size is the deciding factor, I dont want to give up the back of my Yukon. Tuned to about low to mid 30 Hz. Speaker and port direction is not important. Double baffle flush, bracing and kerf port.
