Enclosure Design for Durans 8, A huge tapered horn.

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.

I like teh lows, looks like some polyfill is in order. Thank you Josh!

The woofer will be loading the corner, port up, I'll have to get working...two horns to build now!

Try it without polyfill first

Of course

what driver

I guess a "no name" 8", I got the T/S's though.

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.

8th space ( corner loading )

Should be very impressive for a little 8"

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
