In Reply to: RE: You need to know what the impedance of the tweeter is AT THE CROSSOVER POINT. posted by Mr. Dick Hertz on December 17, 2011 at 20:05:10
From the data shown in an earlier thread, the impedance is around 5 ohms at 3 kHz and the impedance curve is very flat in that region. So a 1.5 ohm series R and 20 ohm parallel will give about 2 dB attenuation and keep the impedance the crossover sees fairly constant.

What should the rating in watts of the resistors be?
I'd use Dayton non-inductive 10W resistors. They are available from Parts Express, and are inexpensive; but quite good.

OK, thank you very much for the help. Finishing the project will have to wait til the first of the year, however. I leave tomorrow for Kenya to have Christmas with my son who works for the Clinton Foundation battling AIDS in Africa.
