Design for 20hz low freq extension.

You are going to have to invert mount the subwoofer, and you may want to play with dampening materials in the line. I really have no way to know what the freq response, efficiency or excursion will look like, so you may have to play with it a bit to find what you like best. Room placement is going to be important. Another driver may work alot better in it.

The best placement I can think of is, in a corner with the vent facing the ceiling.

I had to resize the pics, if you need bigger pics lmk.

Well, I was able to solve a few proplems I was having with horn resp and get a response graph together, mind you the graph just gives a perspective.

Btw, I did not originaly use horn resp to design the enclosure, just my speadsheets and some math. Cool

8th space ( corner loading )

I have a folded horn design that is similar to that with a 100 w to a lil 12. Blew my f-ing brains out man! It's theater style bass!! Lots of boom and earthquake bass ha ha ha
