kdeezy Posted March 30, 2008 Report Posted March 30, 2008 I'm designing a box that will hold 4 18" subs it will have an internal volume of 32 cu. ft i want my port to be in a shape of a cross with all sides having a length of 11" giving me 605 sq in. how do i calculate the lenth of the port to tune it to 35 hz? can i just take the square root of 605 and use it as the height and width on carstereo.com port calculator or is it harder than that?
Torres Posted March 30, 2008 Report Posted March 30, 2008 with the port calculator i have...i cant get the tuning down that low. what subs and amps? that seems like a mighty big box imo
