No. Any added resistance should be added to Rg, not Re.
Because TS parameters is relying on Re when calculated.
While you could argue that the result is the same (or at least appears so in the SPL plot) for a single driver, adding a second one will give a wrong result.
And if you recalculate any value after Re they will change to a wrong value as well.
Not to mention the Pe calculation and electrical impedance will be wrong.

I never thought about multiple drivers. Good point David.

Hard to argue when you make sense.

Most inductors will not add that much resistance in a single sample but multiplied they will run everything off the rails.

When adding an inductor to a tapped horn sim, should I add the resistance of the inductor to the Re value, in the same way that I add the inductance to the Le?
Thanks in advance

yes and the cables too.

Hi,

Agree with David here-above,

Yes, that procedure would work but its not a good practice because the fundamental T/S would be affected too, i.e. Qes would be more lossy and Qts will thus alter if pressing Sd at the HR main input screen.
IMO: More convenient is to add the inductor resistance to Rg.

Thanks for all the replies!
I will add the inductor (and cable) resistance to Rg
and the inductance to the Le value

Hi David_Web, Mark and Oliver,

Thanks for your feedback on the slider operation. After giving it much consideration I have decided to leave things as they are, at least for the time being.

I have found that the new system is not too bad once you get used to it, particularly if the slider values are set by clicking rather than dragging, and the sensitivity is managed dynamically using the Spacebar key.

The same slider operation is now used for all loudspeaker types. Previously the tapped horn system was different to the others.

The auto / manual settings will continue to default to manual once the Loudspeaker Wizard is closed.

Kind regards,

David

Default Auto v. Manual

Hi David,

I vote for manual over automatic as a default. (I know I don't have a vote, but I can keep on dreaming, can't I?)

Thanks for the latest greatest, it works for me.

Regards,

Could we at least get the auto/manual toggle buttons on the first page so we don't have to switch pages back and forth every time the wizard is to be used?
