Does More Box Volume = Louder?

[QUOTE="winkychevelle, post: 8816996, member: 611804"] Port air velocity doesn't have much do do with mechanical power handling as the volume of air that is moving though the port same and it has the same resistive value that's how you tune the box the resistive value of the port. We use larger ports to cut port noise and in some cases we use such large ports to become more efficient albeit in a very narrow frequency range since once you go too large on the port it becomes a huge leak at most frequencies other than near tuning. But with the different dead air inside the box you get different air spring effects just like a sealed box. And just like a sealed box more airspace means less mechanical power handling and the ability to play lower on the same amount of power. But as with anything their are limits. Too big and the speaker is near infinite baffle and relies solely on mechanical suspension. [/QUOTE]
