I want to build two reflex enclosures, each containing a pair of JBL 1401nd woofers. These are the 14 inch units used in the DMS-1 monitor. The problem is, I can't seem to get the net volume and port size for the cabinet. JBL doesn't have the Thiele-Small parameters for this driver either, so I can't use a box program (I could only get parameters for the 1400nd, which I'm not sure is the same unit). Can anyone point me to a source of information? I will really appreciate it.
