Default 2.5 way impedance

Hi,
This question is going to be incredibly stupid. Please bear with me. While building a 2.5 way system using two 8 ohm midbass units, the nominal impedance of the system till the tweeter crossover frequency will still remain 8 ohm, right?
One more thing. Are there any good websites to learn about 2.5 way speaker design?

Thanks,
Vivek

No. Its 4 ohm bass and 8 ohm midrange, sreten.

Thanks for that reply but how does the impedance change?

Just like Sreten said, it is four ohms for low frequencies and 8 ohms for mid frequencies. At low frequencies, both drivers are effectively connected in parallel, at mid frequencies a series coil effectively disconnects one of the drivers.

It changes at the 0.5 way point ~ 350Hz, sreten.
