How can a zobel add an order to the slope of a crossover?
 
I had an e-mail discussion with Bob Brines (thanks Bob for all af your help ;))

And he told me that the XO he uses in his peerless pipes

Isn't 1st order on the tweeter (1st+impedance correction)

but that the zobel is mistuned (compared to the tweeter's inductance), and by doing this, he added a 1st order electrical slope to the existing 1st order, resulting in a 2nd order XO



I've never seen this before, can someone explain me?

series xover
 
Bricolo,

That's a series xover, so presumably the zobel on the bass unit has an effect on the tweeter..........

I've often wondered if, in a 2nd order low pass xover, the LP cap and the zobel components could somehow be combined.....

any guesses anyone????
