T line enclosure design help needed

[sweety 10+ year member]

Hi guy's, I could do with some help please. I'm wanting to build a T line enclosure for my 10" JBL GT3, the Fs is 35.3 & Sd is 346.0mm2 (measured the sub & got 8.25" from centre to centre of the suspension rubber) if i've worked it out right I need an 8ft line & 53.4ft2 of area but have no idea on how to transform these figures into the measurements for the enclosure. The max width the enclosure can be is 3ft, the max height is 17" but depth isn't really a problem

Cheers in advance

Do you want a slotted port or aeroport design? You can make a transmission line enclosure with each design that will sound the same. Aeroport would be a lot easier because you can tune it. I can't help you with Slotted, but I could give some advice on aeroport if you want.
