Thanks, that's been my general thinking as well.   While it does make sense to choose to use one if circumstances dictate, this recommendation was for any diy sealed sub and was wondering how many do it or for what reasons they did it for a specific build.   Sure isn't much available on the subject even with a general search, either so it doesn't seem to be a popular thought....

Didn't see anything on this.  Came up in discussion on audioholics where someone is suggesting that is something to do to prevent over excursion particularly in combination with eq/boost.   Anyone use a protective high pass filter for their sealed subs?   @Ricci do you use such when testing?
