Okay so I am cosidering buying a 12" Type R, with either a Infinity 1600a or Alpine M500 amp (I haven't decided which one to get), and need a box. I am considering making a vented one because I heard they sound sweet. I listen to mostly rock, posthardcore, electro, metalcore, so I want bass clarity, so I was looking for a port tuning of 32, so it's still loud but clear. Anyway, have no Idea how to design one, so I was wondering if any of you have any specs for one? Thanks!
