Hello people 🙂
im new to horn theory, im trying to design my 2 future bashorns in hornresp. For music, cornerloaded, wish for 30-125hz..
My mouth area is lacking, going square only affords me 5,3 ft2/0,5m2) i cant go wider than 2,3 feet but i Can make it deeper.
think i read somewhere that rectangles should be Kept at 3/4 ratio for best result. Whats the consequence of going to 1/2 for example?
is there a tradeoff to be made?
Best regards

+1 if setting hard and perpendicular on a rigid/massive floor/whatever for true mirror imaging, otherwise the pioneer's 1:1.273 was near enough acoustically to a square mouth.

Morning people and thx for the answers, much appriciated!
hmmm follow up question on weather or not my situation is that.
yes horn Will be truly corner loaded, my lounge has a mezzanine above the front of the room, so i Will make a Big Hole in the mezzanine floor in each corner and Mount the horn in it. Termination of Horn mouth Will be flush with the ceiling Below and in the corner. 3/4“ plywood backer and 3/5” fiber cement board. is that rigid enough to quality?

Honestly, health is such that I'm having a hard time visualizing it ATM, but as a general rule, 3/4" no void marine, BB, apple, plywood panels is plenty rigid enough for bass horn construction with bracing only required once it's > ~4 ft square and assume the cement board is for external damping/mass loading.
If wanting to use other materials, then use thickness based on the 3/4" ~1.8m psi MOE.

Completely understandable you could not visualise it, as i didnt make my point clear… i was talking about the Wall construction in the room, to get your oppinion on weather or not i can do 2:1 or should stick to 1:1,273 for best result. horn Will be constructed of 3/4” bb.

If you cut a triangle in the ceiling it wouldn't be too easy to guess the profile. If you came fair into the corner instead, you'd be coming down to closer to a conical profile which lacks the previous expansion.
Therefore I'm sceptical when you say..

As it turns out, the devil is in these very details.
Hey guys, thx for responding, need all the help i Can get….
im not going with a triangular mouth, would maken mouth are even more measly…
allanB, english isnt my first language and im unsure what you mean by “coming fair into the corner”?
grindstone, im assuming that your attached file shows the only Way of truly cornerloading a horn.
in that case i learned something new today 😀. its unclear to me if This mean i should use 1pi instead of 0,5pi in hornresp, Or is it more a question of defining “truly cornerloaded” correctly?
thx for suggestion horny, klipschhorns maybe some day, currently enjoying pi7 cornerhorns.

Yes, I meant what grindstone showed.
If you understood, it means there is no way to properly blend an expanding horn to a corner, and 'true corner loading' makes less sense than simply saying you're terminating it in eighth space.. which is what hornresp will calculate for you.
If you were waveguiding then it would be a different story. Instead, some that put their horn mouths in corners only blend to the floor (or ceiling or one wall), and use the space above to continue expanding.
Therefore I'd encourage you to simply experiment without overthinking this, at least until you're ready to do a full analysis. 😉

makes sence! eight space it is.
cool, no overthinking then. Not sure i Will ever get to the point where my understanding Will allow me to do such an analysis..
thx for your answer.
