Hi tinitus,

Actually, that's a really cool fold. You should work it out into an actual example.

Regards,

Making line drawings can be deceiving, once you add in the actual wood thickness you often will find not as many folds will fit in the space you want.

i was talking about the difference between simulated volume vs actaul bild volume.

I expect it would work with smaller woofer, and not too low

Default double 3 inch

Hi, started playing around with Hornresp a little ago... the wizard is great fun. But I would like to run a sanity check with you guys. I have simulated a TH with two Aurasound NS3-193-8 (mainly because I have a couple of leftovers), and I sort of think the result looks too good to be true. That generally means something is off. Please have a look, feedback is appreciated.

from here it looks ok,only the input voltage should be 2 volts for 4 ohm(8+8/2)for 1w/1m

Ah yes you are right! Now the gain seems a little more reasonable, thanks!

pulling this very nice 15" out of my bass guitar cab (to try a differnt model with more midrange extention)
fortunately FaitalPro have been clever enough to size all their 15" woofer chassies equally, even when of different designs

so I may have this to try in a sub, either BR, or 6th order BP
6th order seem to end on 100liter netto, so that seems quite ok

but would also like to know how it would work in TH

anyone want to model it for me ?
