Hello community,
because i have a lot of time these days, i started to build my new PA.
Because it is fully horn loaded, i need a midtop playing from 200hz, i was looking for plans the last days but i couldnt find anything... Is anyone here knowing some Horntops? Most likely i would use 10" and 1,4", the 18sound 10m600 is looking great for me.
I found DDS Horns, Design Direct Sound, DDS, fiberglass horns, horn lenses, fiberglass lenses, line array, waveguide, waveguides, asymetric, community, tweeter horns, mid-range, speaker lenses, speaker horns but there are few information on the website and i have no idea if they send to Germany. Anyone maybe having experience with them?
Would it be possible for a beginner to calculate such a horn on its own? What program should i use then?
Thanks alot for help

Hi kallle76, I've build a horn box for my JBL 2123H (125Hz to 5000Hz)

A true 200 Hz horn will be quite large. You can use Hornresp to calculate the power response of the horn. The papers here will be useful:
AES Papers -- Official website of D.B.Keele
a basic estimate of the directivity of the horn is the solid angle described by the horn side walls.

I have calculate my horn design (constant directivity) using my JBL 2123H thiele (small) parameters.
use your 10" 18sound 10m600 between 250/300-1200/1500 Hz (Resonance 70 Hz, EBP 280 Hz), and your 1,4" drivers since 1200/1500 Hz
You can download the 18sound 10m600 tiele parameters here :

Thank you guys.
With what toll did you calculate this? Do you have any measurements? I dont think the 18sound will fit properly in this when its designed for the JBL...

hi
as Kipman said Hornresp software is a free and very good simulation software.
Did you decide allready on dispersion, compression driver and horn for you box?
dispersion matching at crossover should be considered in the project (excuse me if I state the obvious!).
1,4 inch is good, will allow you to use a low crossover point, good cheap horns are 18sound xt1464 (60x40 dispersion, you can use 1 x side in narrow rooms or 2 x side in wider rooms) and rcf hf950 (90x50 dispersion, better 1 x side).
have a look at mt121 midtop, although loaded with a 12 inch driver should give you some ideas on the horn size required to get real loading to 200 hz. it gets big.
have a look at Peter Morris and Chris Grimshaw vented 2x10+cd speakers, probably more output than you need, much easier to build store move and setup, and both go an octave lower.
I understand the fascination of hornloading - i built and use an almost fully hornloaded soundsystem - but when it's about midtops that you have to raise, i would think about it twice before committing.
consider also hybrid options like seeburg k20, still more rewarding to build than a square reflex but more user friendly.
if it has to be horns and you are entertained by building them check out also Art Welter SynTripp on this forum - spelling is shurely different - to check a Unity pa horn too.

Thanks for your advices. Yes i tried Hornresp but i have no idea how to use it properly... I mean 10'' Horns are simulated very huge with that and i dont know how to change this. Yes i am planning to use a 1,4'' 18sound with a original 18s Horn as compression, i did not decide for a dispersion yet, what do you recommend for outdoor usage or in a big hall? Crossover should then be at about 1,2khz. The Mt121 is my favourite too until now, but i wonder if there are no Horns to buy in this size.. I'm thinking of something like the F1 Evo or sth like that. And yes i do need a Horn, i use SBH and HD15 for bass so i need some good fitting speakers. Due to mass of time i have these days, i woudl try to build my own Horn out of GFK (is it FRP in english?).
The bigger Limmers eg 312 (as linked by Kipman in the 2nd reply) are the closest you'll get to a manufactured horn for low-mids like you want.
GRP (Glass Reinforced Plastic) or just fibreglass would be the common ways of saying it in English.
Cheers,
David.
Yes, i know these Limmerhorns but i dont like the speakers they are designed for... my problem in Hornresp are the higher frequencies, i can design a Horn playing great from about 20hz with nice output but i have no idea how to get it playing to 1khz, do you have any advices for me with that?
And did anyone of you maybe heard of the SRAM 2x10'' Horn? I read alot about this but i cant find any plans of these..
