new idea for a bass horn
could be the next project
based on my experiment here, I have concluded a big midbass horn is tricky
but also that it reproduce with a special big tuneful sound, and almost addictive

Is this a W horn with a mid/treble pasted onto the front panel?

my understanding of a w-horn is that its a bass horn
I guess you could call it a w-horn, since it looks like one
apart from its calculated to only 120hz(+/-)

and yes, the small widerange drivers on the front is an ispiration from Ingvar's Hilden horn project

I suppose you could add ports to the rear chamber to improve LF response a little.

Hornresp has this option.

would need much bigger back chamber ?

its not a real tough woofer
rather cheap 12" (Sovereign 12-300)
but ok quality with nice midrange

just realised why not to use ordinary medium Qts drivers for front horns
and pretty obvious, peaked low rolloff in a small back chamber
apart from that, a 150hz horn looks easy
use all the available space for a backchamber it might still be possible

btw, I tried a small Onken slot port calculation with the 12" Sovereigh, and looks like it would work nicely

another update on my weird xo

I can now fully understand why some people wisely avoid multiways for bass guitar
several times I have experienced tuning and pitch to go complete wack(off)
its certainly not simple at all

next crazy project, big weirdo 18" 'fullrange'

Which modeling program are you using?

It's certainly not been easy, but in my case I have been really happy with the results once I threw enough time (and money!) at it.

ears and my guitar

actually, my ears just went complete wack
one ear closed, and it hurt a bit
changed a few resistors(again)
ears improved immediately
as did my playing
sound as such doesnt change much really
its all mainly phase issues

sure, crossover is not too good, its crap
just fooling around, needing components
in the meantime, I put my ears at risk
and its not a joke
