I see some problems with it:
1. Cross-section appears to be pinched on the first 180 degree turn after S1
2. Cross-section seems off on second 180 degree turn after S1
3. Is correct expansion followed at the top of the horn?
4. Bracing?
Just to clarify -
The amplifier is considered to be an ideal voltage source Eg in series with an internal resistance Rg (also known as the output resistance).
Eg = Amplifier open circuit root-mean-square voltage.
Rg = Amplifier output resistance.
When the amplifier is connected to a load -
Eg will be the amplifier output voltage only if Rg is zero.
If Rg is non-zero, the amplifier output voltage will be less than Eg.
