Re: Sealed vs. Ported Subwoofer Enclosures in Pro Audio
I think it comes down to a couple of things (one of which at least was missed in the linked thread).
First is to identify the intended purpose of the project. Steve B in that thread clearly made some assumptions about what level of output would be "useful", however if the project was just to add a bit more bass to a home stereo for example, then maybe the lower, excursion limited SPL of the flatter design would have been acceptable.
Secondly, as a sweeping generalisation, the more compromised one's starting point (eg by budget restricting driver options), then the more one would have to deviate from the ideal and use the various compromises to yield a practical end result.
(Having said that, as Per mentions, there are clear examples of much higher end projects also starting with nothing like a flat response - lots of EAW's subs for example, as attached. Just goes to show that it's not easy to make a completely representative generalisation.)
