[QUOTE="DNick454, post: 5942499, member: 600755"] I know this is a really old post, but I was just reading through here. One thing you forgot is that the port calculator doesn't have a provision for multiple ports. If you only used [B]one[/B] 10" port, then yes the tuning would be extremely low. Type in 15" into the diameter of the port, 15" diameter round port has approx. the same cross sectional area's as two 10" ports. If you do that, and type in 30Hz, if will give you back like 23 and some change for the port length, so don't worry, his tuning is spot on [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] [/QUOTE]
