Hi,

Does anyone has ever seen/build a horn like this?

The horn resembles very much the Vulcan horn as well as the manifold horn (Olson/Manaoka type).

The driver parameters are as follows:
Fs: 35Hz
Vas: 160 liter
Sd: 325 cm2
Re 7,5 ohms
Qts: 0,4192

My intention is to learn how to calculate similar enclosures.
The horn sounds grate. Unfortunately there is no chance to compare it to other designs nor to run software test without the exact dimensions.


Thanks in advanced.
