I agree with Wolf's suggestion. An LC (or LCR) trap across the driver is one of the few things that works pretty much as expected in series crossovers.
Keep an open mind, but don't let your brain fall out.
Getting there - the top end seems better now. Maybe a little too forward around 1-2K now. But my allergies are raging today, so maybe not a valid observation. I'll live with this for a few days.
Played around with this for the last week but just couldn't tame the tweeter. I think the series network must have been creating a HF lobe that was bouncing of the ceiling. No matter what I did, I couldn't get rid of the smeary chirp I was hearing. So I broke down and tried the parallel model. That was the ticket. I've been tweaking on this today and this one is the winner!! Sensitivity is really low and it's a few more parts, but I'll gladly take that considering what I'm hearing now.
You'll notice I carried the LC idea over to help pull the woofer down. I learned something new with this project to add to my toolbox, so that's a win!

Thanks Wolf! I'll give that a shot first and see how things look.
This is a nice gesture. Looking good so far.

Thanks guys!
Looks like the woofer is driving that 1-2k hump, maybe bigger L2?

If you now add the tank cap across the lowpass coil, that breakup bump will likely be suppressed further.

Will do! I'll never hear it, but younger folks might.
-- Looks like 0.22uf will do and only adds $1.18 to the total cost.
