[QUOTE="Mr Cabinetry, post: 4809925, member: 571490"] The port does take into account the xmax, cone to excursion displacement and power = vent mach. Now, way back when the arguments, debates and discussions were going on about vent mach, port velocity, laminar flow and all that good goofy business was " what is the acceptable ratio of air movement thru the port?". The consensus was .20 meters per sec or 65 ft per sec, anything above those numbers was considered " too fa king high " which is total bullsh!t because that would mean the port area takes precedent over any other design element given the max size the enclosure cannot exceed or design limitations the enclosure needs to fit within the install. However, conforming to the established " NORM's " means " one must adhere to and not deviate and anything other is subject to speculation ". Specifications, Requirements, Fit, Function and Design = All Covered. Job Done. Customer = The Final Word. [/QUOTE]
