[quote user="noviygera"]I got this new midbass horn to replace the Edgar 80Hz straight horn. It is made by Funktion-One and they claim it plays down to 90hz. I could not get it to play below 120Hz and I am trying to figure out why.
15" driver....

Now I have been listening the different crossovers trying to shape the new Macondo general balance. This is so fascinating ceremony that I do have a lot of fan. The things doing alone very well. I boosted upper bass and it worked now very-very well....

Hi,I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...

A friend stopped by tonight when I was test-listening my midbass horn. He got freaked out from the size of the thing. I played for him some Gerhard Oppelt’s organ recordings. He told me that I am crazy, like I do not know it myself. Anyhow, he made a...

Dominik, Jessie is right - it is irrelevant the precession of your profile if you horn does not go to high into HF. The LF gain of upperbass horn happens in the first half of horn anyhow. I do not insists that I am right but I have a hypothesis that ...

Of cause it shall be mentioned in the context of thin there that there is always the ALE Acoustic solution. The Japanese ALE Acoustic make two midbass drivers: P1260 and P160.

[quote user="ulf"] Well, it was not really a surprise to us that the horn without the phase plug was dissapointing. Without the plug we had a horn that was a bit too short, had too large front cavity and less compression than we desired. [/quote]

For me personally, midbass is the most important frequency range when it comes to sound reproduction. I believe you will be on the right track to focus on this range because so often it is overlooked and treated with super...

Gera, if you would
like to incorporate the Western Electric 13a with 555 then you need to make a decision
how low you will drive it. You chose the 120Hz but it might
not be useable frequency, it might be much higher in order to get “better”
sound...

Tonight I finished two
horns at once. One was a shortened Goto S-150 horn that now has a
Fane S 8M, without back chamber so far. Dimensions are now 1.1m deep, 11cm throat, 75cm mouth. It is replacing the Avantgarde
Trio midbass horn r...

Thanks for the detailed answers. I will explain my setup.You are right about the dipole bass correction instead of the injection channel. Since I am waiting for both a subwoofer and the Fane Studio 8M and their horn, I am using the 12" as a b...

I had quite a number emails from different people who picked 515G or AK15X drivers and would like to build a midbass horn from 60-80Hz to ~500Hz. I played a lot with different 515 (B, E, D, A) and with different AK15X but I never went for the right h...

Hello Romy,The tapped horns were easy to construct so I made them while I was working on the midbass channel. I can't really comment on how good tapped horns are because I have never heard other 20-35hz capable systems... it does provide amazing SPL'...

It sucks – whoever builds horns too damn far! I need to see my congressmen to lobby lowering taxes for horn users of something like this….

This connection is the only connection that my horn will have. From one side it will be back chamber with hard-attached first section. The first section is very critical as it has a transition from 7” round throe to trapezoid of the rest of the horn....

Maybe the upper midrange horn became like a paper cone speaker. Best sound I ever made, and it looks like this. It had the same ring to it as the magical SABA fullrange speakers - made of paper. But below 500Hz, I must use solid wood. The Fanes are t...

The idea of conversion of “midbass hanging thing" into upright flower horn is brilliant in my view. To curve the leg of the horn to offset the sender of mass and the horn might be opening up as nuclear bop mushroom. I wonder how good it will with 500...
