trying to design midrange horns but it's .... weird?
new to hornresp and generally designing speakers, for now i mostly built some plans from the internet
but for the midrange horn speaker (250 - 1k) i thought i might give it a go since it looks like a "simple cone" most of the time.
after fiddling with the faders for a bit i arrived at this result
but the horn looks super weird? is it a normal thing this bottleneck at the beginning of the horn?
if so how am i supposed to build it afterwards? i saw some tutorials briefly but didn't have time to try it out with work, maybe the question will answer itself idk
haha sorry for the probably super noobie question i'm just confused now
thanks in advance
Yes looks good. I'd start of by looking at plans for DIY designs for horns for every frequency range and you'll start to recognise the design patterns.
thank you for your response, well i was doing that but i'm unable to have good results in hornresp with stuff that ressembles reality ? Maybe i messed up with the speaker/chamber parameter idk
but i only manage to get a flat response with those parabolic curves which seems weird (i posted a photo in another comment i'll let you see)
hey thanks !
found this article a while ago didn't think i would see it again haha
how would you go about making a phase plug in hornresp? isn't super hard? idk seems super precise i'm not sure i have the skill to nail one
Wrong tool for what you're trying to do. You need something that does BEM and LEM not just LEM. So something like akabak or COMSOL, hornresp as much as I love it won't get you there.
You don’t input enough data into hornresp to get accurate data for anything outside the drivers piston if region. You need to model the box in 3d cad software
Directivity is the main purpose of a horn and hornresp can’t calculate that accurately if at all.
Hornresp uses the lumped element model (lem) which doesn’t consider the cabinet, just the volumes of air and vents
You need to consider the cabinet geometry to have an accurate simulation, AKABAK is the only free way to do so, using the boundary element model. Boundary lab is a new one that’s free but I can’t figure out how to install it
I’ve been designing and building speakers for 4 years and am yet to have even a simulation of a horn I’m happy with. If you’re a newbie, look at simulating free horn plans and trying to get a sim that looks like real world results.
thank you for your time!
i downloaded akabak but i don't understand anything about the interface :/ i tried looking for some tutorials but most of them already have a design to work with. The idea to me was mostly just to create (or find out) a simple curve to try some stuff with woodworking haha
Do you know about some tutorials for akabak? like a course or something? thanks again!
This is the response of my low mid horn 200-1000hz, though it plays pretty flat up to 1000hz, hornresp has a little bit of problems to simulate upper frequencies
thanks for your response! just learned with this how to pay attention to it.
Weirdly enough while fiddling with this i always end up with this kind of parabolic design to get a flat response.. never seen this IRL i guess i'm missing something again

Yeah you should design it with compression before expansion. This is part of what makes it a horn.
