Hi, I have question about resistor in tweeter crossover.
The tweeter is a Scanspeak 6600. The crossover is a ( sine-cap ) filter.
No capacitor, just a inductor (0.12mh) in paralell and a singel resistor in serie.
When using singel resistor, in my case a 8.2 ohm ( - 9,7db ),the total Z-total is 12,22 ohm.
( rest of the speakers is 8 ohm, bass 87db, midtrange 88db ).
When using L-pad the Z-total is always 4 ohm.
Is is best for amp to see the same resistens?
So a singel 3.98 ohm (-6db) wil give me 7.98 ohm Z-total to match the rest of the system?
To do it moore difficult the tweeter is buildt in a waveguide, thats why I dampen the tweeter so mutch. A waveguide give +6db from 2K-8K.
And read somewhere that a singel resistor dampen ekstra in that range ( :
What do you think?

I think it makes no difference for well designed amp.Is is best for amp to see the same resistens?
Keeping impedance constant 4 ohm won't make
a significant change because of amp output impedance that is way lower ( specified by it's damping factor).
