For designing speakers that require filtering, non-classic alignments and accounting for cabin gain, I recommend Brian Steele's PORTED.XLS spreadsheet. (diysubwoofers.org/design/ported.zip)

Hi Patric

I have a infinity woofer who I did want to use for a tapped horn, because I did read your stuff in my learning proces of folding and designing a tapped horn I begin to think of a tapped horn in home envirionment is a need, I have A PPSL box designed but only in sketchup, and busy with that tapped horn with the infinity 1260W

Something is wrong, when I try to make a vented box as a opening to tapped horn like you advised here I get not a very good respons from this woofer and in a closed box it get high fs.

I put here some stuff can you let go your experience around so I learn more, I am a amp designer that is for me not so difficult but box yes I have to learn some things.

Further I think the TS are some strange, but when I do a chech with martins TS check sheet it looks everthing is fine, maybe you can check also, see al in the pictures.

I do ask also to prevent use a wrong speaker, it has such low qts for such high mass??, I do when I am ready with the box use limp to measure manufactorys are not always trusted, infinity is a good label though see pdf for TS parameters...

Thanks

kees

Isn't that more of a TL than a tapped horn?

Looks like a tapped quarter wave pipe or tube (TQWP or TQWT)...no flare tapped horn.
