Re: Sealed vs. Ported Subwoofer Enclosures in Pro Audio
Using the scientific method of MNAUTMS* I came up with these plots. I used WinISDs suggested box size/alignment, put in a signal at rated max long term power and played around with a BW HP filter to keep cone excursion in check.
For comparison, a 18SW115 is simulated in a vented box using the same methods. To me, it looks like it will behave very well in both a sealed and a vented box. Obviously it has more output in a vented box, but as far as I can tell, it would sound pretty good in a sealed box.
If I were to build any of these, I would probably select a 18SW115 based on these simulations. The question is, can we actually trust them? Is it this easy?
