[QUOTE="tRiGgEr, post: 953714, member: 552295"] Depending on the speakers size and XMAX. This will determine the amount of port area to use. Here is a site with a ROUGH calculation on port area. Do not take the number it gives you as the holy grail. [URL="http://www.carstereo.com/help2/Articles.cfm?id=31"]http://www.carstereo.com/help2/Articles.cfm?id=31[/URL] Also In designing a port to minimize port noise a ratio of 1:8 is Ideal. But I always use 1:6. [/QUOTE]
