[QUOTE="Thepro47, post: 3065857, member: 577312"] Hi There... I am currently ordering my subwoofer : JL AUDIO 12w3v2-D4 Since shipping takes long to Canda, I have plenty of time considering my ported box As you all know I want a ported box for my sub. The recommanded frequency and ported box volume for the sub are 30hz and 1.75cu.ft. respectively. I did some rough calculus and I ended with something like : port lenght = 10in long and 3in as for the diameter. I was wondering if I did things right. 1st : do you think putting a 12w3v2-D4 in a ported box is fine? 2nd : do you find those box specs right? 3rd : whats the right formula for frequecy / port lenght / port radius? Thanks for replying aswell as reading [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] [/QUOTE]
