no. i am a complete novice and just doing this as a bit of fun.

what would be involved in modelling it on horn response? if you could do the auto cad and what have you, i would be very grateful.



you'l never know if you'r horn is good at all intill you input it into hornresp. intill then you, nor any of us will be able to tell you that it's worth trying out. the drawing is looking better, but theres no inputs to go by. once you learn hornresp it should be easy to help you out after that. plus by supplieing atleast rough measures *incase you want to keep the design for copyright reasons* it will help others try to tweak the design slightly to help increase or decrease certain aspects of the design.

Hornresp is pretty simple once you understand the inputs.  Search the forum on it and you'll come accross a lot of good info (including where to get it).

@norty303 - as regards to your comment about the horn getting largaer and then smaller, i have made some adjustments. added about 250-300 mm to the height and changed the folds abit

Maybe we should spec required freq resp, and then arrive at the best way of acheiving it.

I personally think a WSX would be a good design starting point,

Did have plan for WSX with internal dimensions here, but edited it
out so speakerplans.com doesn't get slapped for
encouraging copyright theft.. WSX internal here

but with simpler driver mounting, access plate heatsinking, sensible 1850 compatible rear horn chamber, resulting in a final design with 8ft+ horn length, that does 38hz to 150 "flat", without over excursing driver. I wouldn't mind carting 4 of these around if I knew I was guaranteed 38hz, without ridiculous eq or blowing a few xmechs/xmax's every gig.

Do your simulations, decided on your compromises and when your satisfied, build a prototype.  This being said from someone who is in this as a hobbie.  Building them is more than half the fun.  If size doesn't matter (depends on who you talk to), why not?

If you have access to AutoCAD, Graeme has a very cool program for doing horn foldings on his sight.

try something like this, though maybe not as many lines but something simular. try a HxD of 90.25cm high and 90.25cm deep. and also try a width of about 76.2-76.25cm, that should give you plenty of room.
