What Hz should I make each port in the box i am building for the loudest SPL? I am using 2 15" PowerPlants. I am thinking about 22hz? That sound like they will be loud there or should I change it to make them louder?
yeah I would say tune it to around 45-50 but what you have to remember is that if you play tones lower then your tuning freq without a subsonic filter on you will damage your subs. unless you are gonna TRY to compete with fusions(I wouldnt but you never know some people may try) take the subs FS and tune within 5hz of that.
