Xover and Tweeter phase advice

[Lessandro]

Do you think the tweeter phase could be negligible? Does the crossover seem well done in general? I'm a novice, I think I did everything correctly, but maybe I'm wrong.

With only on-axis frequency response measurements it is hard to tell.

I would measure the drivers off-axis and add those measurements to the driver profiles in VituixCAD.

At a bare minimum I would measure them at 30 degrees and 60 degrees off-axis, but 15, 30, 45 and 60 degrees off-axis would be even better.

EDIT: With regard to the tweeter phase (I assume it is the blue plot), it is not terrible, but it could be better.

Looks like a decent start but will second the need for off-axis measures to really determine. Not sure why you would want resistor in series with the woofer and is a rather large inductor on it. The tweeter looks a little hot so might want to attenuate it more.

Did you run the Optimizer Tool?

1. What specific drivers are you using?
2. Where did you get your measurements from? Did you trace these or measure in box?
3. Series resistors on woofers should be avoided (unless these form part of a notch filter). that is the woofer sets the overall system sensitivity. If you are having to use a series resistor, then I'd increase the series inductor or parallel cap to achieve the desired slope. We don't want to waste precious woofer sensitivity in resistance. Besides, this series resistor will see a lot of power (100w+) so you'd need to size it appropriately (or parallel many higher value / lower power resistors). Hence why we avoid such designs.

This looks like a purely theoretical design on an infinite baffle. Did you do any baffle step correction and enter the X,Y and Z coordinates ?
