[QUOTE="Notloud00, post: 8268190, member: 578051"] You wont know until you build it. I would build a sealed box with a qtc of .707, find the resonance, do a 1:3 ratio ratio and use 1/2 cone area amount of port area tuned to the sealed resonance and just see how it sounds. To peaky, shrink the front, doesnt play low enough, tune the port lower, isnt loud enough, up the port area, subs unload to easy, make a loading wall. Once boxes are in the car its all testing, why do you think all the big 4th order builds have multiple test vids with no port and differnt ports? Its all about testing. Just make it to where the front can be totally changed and just goof with it. Thats what it is all about lol [/QUOTE]
