First Crossover design: Xsim questions

Hi,

I am designing my first crossover using Xsim. I am using Scan-speak D2904/710002 and 18W/4531G00 for a 2-way bookself. Both drivers are 4 ohms.

I notice that the impedance of the midwoofer drop lower to 2 ohms after my crossover. I know that it would be hard for the amplifier, but the impedance is smoother without that two humps.

Would this be a good design? What would you improve?

Here is the impedance graph and design

What's the purpose of R3?

For 4.5dBs of difference between tweeter & mid-woofer both 4 ohms you have to change the resistors value for R1 1R62 & R2 5R89

If you want to flat the drivers impedance you have to use a zobel network.

No I did not. I just get to know baffle compensation. I am still learning it. I have a question for the baffle step compensation. Should I put it on the tweeter or woofer circuit only or in the front of the crossover circuit?

What about this crossover design? I am bringing down the level above 300Hz to match the bottom end. Reversing polarity the phase I think is pretty good. Should I still put a baffle compensation?

Fixing the response above 300Hz is the same thing, so yes that's good. Doing them separately has worked for you and it is a common approach.

You don't need to reverse phase to check, because Xsim allows you to turn on the separate phase plots, which is a superior method.

The baffle step is still susceptible to room placement, room power.
