ouch.
122db with 20watts
thats TWENTY watts. with a 19$ woofer.(US 9$ ) with 3.5mm xmax.
my digital camera taking video,the mic clips heaps with 120db but u can still hear the bass LOL
Theres no real difference either way the horn goes.
Am gona try a DD 2012...(www.ddaudio.com)
This thread COULD belong in the car audio forum-but this is a home audio corner horn.....
+ no one will see it if its in car audio...

not another tasty horn design
Please stop teasing us with another of your wonderful horn designs with the delightful cad drawing to match with so much lovely info on it but not quite enough to copy it. Does this mean I'm really going to have to knuckle down and actually learn to work Hornresponse for myself? Oh well it looks like more sleepless nights ahead then.
Or how about giving us all a nice easy design to let us horn virgins cut our teeth on using some inocuous small driver that is globally available to whet our appetites for something a little bigger?
Or of course you could just carry on teasing............
Whatever keep up the good work.

no free lunch
...if i did that then i could do all the hard work and everyone else can copy my design for free..seem fair?
-including small companys who would like a nice little horn folded up for them for free..
I havent modeled it in 1pi or 2 pi as i doesnt concern me.
But stack a few per side and it will function to some extent-but thats not the design intent.
the labhorn is DOUBLE in volume,and designed for that PRO high power usage.
🙂
like an 8" from partsexpress.com? but i dont have access to those woofers....and im very busy now - work AND tech..... and building my own horns etc...
email me.
Cheers!
would you prefer i never posted them and u would never know what is possible with HORNRESP+ Qcad 1.5 and a little knowledge and advice from forum people?

worse ofcourse! its meant for corner 0.5pi...

what a lovely horn
Did I forget to mention that I think NZ is the best place in the whole world and that New Zealanders are the nicest people I've ever met?
Oh well is late and Horn response beckons.
One question as you seem to have done far more research than me.....I read somewhere that at sub bass frequencies a horn does not actually need a flare as such but can be made up of cylindrical/rectangular sections growing in size joined together and the step between the sections doesn't affect performance.
Any thoughts insites on this? My point being that if straight sections can be joined together to get the right crossectional area then these could also be joined at 90 degrees to make folding the horn much easier.

you have now
yes several conical sections can form one 'hyperbolic' or other horn...but ONLY for limited bandwidth, 1/4wave of the conical sections.
Thats what MINE are incase you saw my site-
model exponential
CAD up horn,folding as i go.
Remodel actual conical shape i have in Cad=pretty much the same!
🙂
btw i hit 126db on my meter today YES IT HURTS i can hear a high pitch tone.
(yes RS meters only do 126db!)
126db with 20watts still-i just played with horn positions,and this time in a 1991 toyota starlet(pics to follow in several hours)
I dont really know if the usual ' cabin gain' is infact doing the same thing for horns as it does for ported boxes-but it certainly is loud.
Cheers!

cool horn. 😀
i though i might have a look at horns, especially seeing yours. 😎
can someone e-mail me a copy of Hornresp, or show me a different link to download it from? when i download the file from http://www.users.bigpond.com/dmcbean/(the only site i found with google), the file is 0 bytes, and windows crashes. 😡
my e-mail is matttcattt@yahoo.co.uk
PS: do you mind if i use/copy your design/s? i will give you credit on my website (if i get round to updating it). 😕

hornresp emailed.
If u want to use my horn,u must use the drivers i did.
If u want another driver modeled,email me
Cheers!

horns are good?
So the sucking up approach doesn't work then!😀
The artical I was refering to was talking about using straight sided cylinders of differing dia's and not conical sections. So that you'd end up with a stepped pipe of the correct length and the final pipe of the correct cross-section for the mouth. So my thinking is if it works with cylinders it must work with rectangular lengths? checkoutthis link to see what I mean
www.fostex.co.jp/int/pages/products/spunits/enclosure/enclimage/87e_encl.pdf
You see not a curve or dodgy angle insight, except for the 45 corner piece. It seems to be made from ever increasing rectangular lengths.
This has got to make folding horns easier. In fact after "seeing the light" with hornresponse and working out what affects what I modeled a horn whose L12, L23 etc lengths were designed to wrap around a central chamber.If this stepped horn idea works then this has got to be worth a try?
Anyway enough of being the Instant Armchair Expert and a bit more of Mr woodworker. I have a feeling that my first horn is getting ever closer.
Thanks for the input.

Nothing is free
because life is short and il die someday thinkn 'i spent far too much time doing long calculations for other ppl ,i cudve been outside enjoying the sunshine and the birds and the trees'
haha! hope u feel guilty now...
Hey...im giving out my plans for free-but u just dont have the same woofer as im using..
when i finaly finalise which 12" im gona use,full plans will be available..

those stepped sections have the same effect really.
for bass it makes no real difference,aslong as the panels are no where near 1/4 of the frequency u want to produce.
my horn has 3 corners and 4 segments...that thing is just another approach.
At the moment i dont see its useful ,the way i do it,to employ this method ...but its different.
