Wayne,

Thanks for the tip. I'll swap the leads to the tweeter and see how it sounds.

Maybe you can help me with a problem I'm having. As I've mentioned, I can't get SPICE to work, so I'm modelling in MS Excel. I'm using the formluas
R(L)=2*pi*f*L
R(C)=1/(2*pi*f*C)
to table reactance of XOver components across the frequency range and using those figures to determine voltage drop across the drivers for a given Xover configuration. The drivers are modelled as Re and Le in series and dB drop is calculated as 20*log(voltage drop).

Is there anything wrong with this approach? I'm not getting the same curves as I see from textbook examples.

thanks,
Gar.
