[QUOTE="Mr Cabinetry, post: 4809665, member: 571490"] How do you determine port area for given design? Do you base it solely on the accepted " standard set of 12 to 16 sq.in. per cu.ft.? " If that were the case here, than the port area should be 6 sq.in. minimum - 8 sq.in. maximum. Or do you base the port area given max wattage applied to determine vent mach of said port to achieve the result which port noise will not occur below the threshold that is acceptable to achieve the function and design goals of the enclosure within the spec's and requirements? The latter achieves what the customer wanted and is to the specifications and requirements as to design and function. Not all enclosures are designed for use as " BassHead " applications and the customer is well aware of that, therefore the "assumption " is one that the enclosure will perform and sound like " azz ".
