Hello guys,
first of all sorry if i'm in the wrong section, but i thought that an help request for a new project is better here...

So here we go,
this is what i have in mind..

It's an Hybrid Horn designed for the RCF LF18G401, in the attachments files you can see the project, the plot and the data of hornresp..










The height is 600 mm and the panel thickness is 18 mm
I have to know if the horn data (Just the horn) are right and if there is something that can be improved..

Tell me if i lost somethings!

The biggest problem for me is to know if I learned how to properly use hornresp..

Thank you for your time!
Good Bye!!!

look like at www.freespeakerplans.com/bass-cabinets/25-mhb-46
this cabin can accommodate rcf lf18g401
this is another cabin like always compatible with your driver, but most will go down in frequency hornplans.free.fr/hr118.html

in my opinion, the first section of the horn (s1) is 360x220
atc in this case is the area of the cone 1220
I believe, however, that will not change much the simulation

Thank you for the explanation of the S1 and the ATC!
No it does not change so much!

Yes is similar, maybe too much... it seems to be a fusion to the mhb-46 and the hr-118...

Anyway it can be a base for learn how to project somethings and sim it right!

By the way new modifications

The red reinforcement is also a protection for the reflex from the turbolence of the cone.. for what i know the reflex should not be placed directly behind the cone
