Okay, so TLDR: it's because correcting phase response to linear for the bass doesn't make sense. The linear phase is not worth the...

Anything wrong with linear phase through the bass roll off?

What's the phase look like without a filter? Are you actually flattening the driver's native phase response by correcting it, or just...

They all have a huge delay, equivalent to about 7 feet to up to 20 feet or so. How is that happening? I've never seen a passive network...

For me there are three things there to see: - the post-ringing is much lower with the LP filter vs the MP filters - the pre-ringing is...

This was my thought too, but I see a lot of DSP experts aiming for minimum phase and I'm trying to understand the thinking on that better.

So you're not necessarily linearizing the total phase response, you're just using a linear phase filter to change the roll off rate...

Can you explain better for me what's happening with the spectrogram? Is this processing delay time for the different filters?

I also prefer LP filters for both crossovers (LPF & HPF) but also for simple HPF filtering when I want to remove frequencies below 20Hz...

I say it all the time, minimum phase might be the goal in analog, but maintaining a minimum phase through the roll-off if you can make...
