Acoustic Horn Design – The Easy Way (Ath4)

[mabat]

Jeez.

Nothing to do with ST260 for sure.

The TD-2001 could work (slightly) better with a higher value of k > a less abrupt opening.

I'm about to order the big sand-printed Faital Waveguides, ⌀494 x 192 mm. The quote is 1150 EUR/pair. Should anyone be interested, please write me aside.

 

[fluid]

Do you know how heavy they will be?

 

[mabat]

No idea. The volume is cca 4.5 litres (dm^3).

 

[TNT]

Guess; density = 1,5 => 7kg?

Exiting and I think I can feel your level of anticipation. So what will the waiting time be once you push the button?

[mabat]

1 - 2 weeks.

The final model of the smaller one (1", ⌀336 x 184 mm). This is 450 EUR/pair.

 

[fluid]

Very pretty, does the back cover fit into the cutouts somehow to keep it in place?

 

[mabat]

No, it's supposed to be a tight fit mounting and I hope it will hold firmly enough.

 

[tmuikku]

Have you published more data on the smaller version in post #4968? Thanks

 

[mabat]

Sure - SH336

What considerations have you done with regards to how the woofer cabinet should look? It's a difficult design to get to look pleasing.

 

[mabat]

I don't think it's that difficult. As the waveguide will be the prominent feature anything unobtrusive will do. One of the ideas is not to use any woofer cabinet at all.

OB or Horn Loaded?? don't keep us in suspense!

 

[Twellmann]

Could be that it's only for playing solo triangle...

 

[JSS]

BTW, in Ath such a throat extension can be added simply like this (that's what I did above):

Throat.Ext.Length = 65 ; [mm]
Throat.Ext.Angle = 3.6 ; [deg]

Thanks Marcel, I'll play around with it. Which of the demo#.cfg's that is close to the ST260 design, that would be a good starting point for tweaking?

How about IB, in the floor?

Sorry I just started learning ATH. I'm looking at the cfg files, I only see term.s/n/q don't see k values. Can you please help point out where I could increase the value of K?

This one's for the HF108?

Is it possible to order this in an unfinished / rough surface (non-glossy)?
