Anyone on here good with sub enclosure design? I have a few questions with regards to internal dimensions that are specific to the subs I have and port length.
10" Alpine TypeX
Vented box volume range: 0.8'-1.5'
Optimum:
External box dimensions: 12.5"x14.5"x18.5"
Gross internal volume: 1.4cu'
Vent area: 11sq" (11"x1")
Vent length: 22"
Vent displacement: 0.24cu'
Net internal volume (Vb): 1cu'
F3,ripple,Fb (I have no idea what this is, sumn to do with port tuning I think): 29hz, 4.7db, 36hz
Question: The above optimum box is 1.4cu', I would like to scale this down a bit but I cant figure out the port size. I've tried couple online box generators but cant make sense of the numbers. The design keeps giving me a port length that is waaay longer than what the actual dimensions of the rear of the box calls for.. eg a 28" long port but a 12x14 box design. Maybe I'm entering the wrong tuning value..I dunno..
Any car audio experts out there that can help me out?
Thanks
