Can irregular-shaped enclosures be ported accurately?

Say a fiber-glass enclosure which is contoured and the exact enclosure volume is difficult to determine? Would it be far too difficult to calculate the correct port length/diameter to achieve a certain tuned frequency and consequently risk poor sound quality or even subwoofer damage?

yes, it's fairly easy. the most difficult part would be finding the actual volume of the enclosure.

Take a rough idea, then using a rough idea of how big your box is, find a good port length.

Cut some aeros to that length, put them in box. Listen. Cut them down, put them back in box. Listen.

Just keep testing until you like the sound.

That's one way, if you are in a hurry. The way we do it at the shop (for our VIP customers) is to use Jello.
