bass speaker help

[tinitus]

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?

 

[tinitus]

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.

 

[tinitus]

would need much bigger back chamber ?

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

latest crossover revision, and now patent pending

its still surpricing how much even small crossover changes affects string tuning and pitch

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

latest crossover revision......

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.

 

[tinitus]

Which modeling program are you using?

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

Depending on how high the basshorn has to go you could use a bandpass horn like the old turbosound ones were.

100hz to 2khz would be ok not sure folded is so good

anyway, I removed the tweeter series inductor
sounds better without it
it dealt with some electronic issue I had with effect units
and those were removed a while ago
the only effect box I use now is a compressor
and only because it gives a little exstra gain I need

 

[phase_accurate]

Up to 2 kHz would be fa too high. Even the 800 Hz that EV used for the old "Eliminator" Basshorns for instance was too much IMO. Let alone for a bandpass horn.

folded bass horn is way too big for the standard famely car anyway
my own next project is planned to be more 'lightweight'

I almost have the sound I like now
its just too heavy for easy transport
so now the challenge is to achieve the same, just in a smaller package

 

[tinitus]

this must be the weirdest idea I have had yet

 

[tinitus]

looks like it will be built

 

[tinitus]

small update

 

[phase_accurate]

This is a quite elegant looking solution but I fear that it doesn't differ that much acoustically from the other horn/reflex hybrids that are around. But it might be a little more complicated to build compared to the latter.

Do you know the cube shaped front-loaded horn from "Klinger". It is quite compact with a side-length of 60 cm. But you would of course need a high-efficiency midrange that goes quite low.

it is midhorn with apperiodic backchamber, not reflex...thats the difference

and I wont risk loosing it because of a too high port tuning

anyway, I bought the plywood today
I need to test it before I build more
2 or 4 would be cool

 

[tinitus]

ahh, since I know it will be the best bass guitar speaker this world have ever seen, why not just build both channels right away ....and thats what I have decided to do
looks like I will need one more 12"
