Hi @Mitchco

I have 3-way DSP XO system.

My drivers are not time aligned right? I need to do more work with the correction designer, iterating.

At the moment, I'm only using the default - also using TTD per driver.

Actually, this is a very good looking result. The step response stays close to theoretical perfection all the way here.

Thanks Bernt! I thought the theoretical perfection would be closer to this blue below.
But it seems my understanding is wrong and its closer to what I already have ?

Yes, perhaps it drops a bit early, but the shape looks good.

Could you post a frequency response of measurement, simulation and target, and a step response of simulation and target?
