Some kind of happiness is measured out in miles
Crossover upgrade was never in my sights to be honest...For me financially it would be a no-go but less than $500 or so to replace posts was within my budget...I have invested many thousands over the years in my system but left the speakers alone...BTW I have never touched the shorting bars (Is that a bad thing?)
Good idea...I'm gonna do that now
0000 steel wool did the job very nicely...
couple of years ago I bought an extra set of 250ti's. one had loose binding posts , you would turn
the tightening knob and the whole thing would turn.
I don't recall if the posts were soldered to the xover, but I did open them (remove LF driver first) and hold the posts stationary from the inside while turning them from the backside.
(allen wrench through the wire insertion hole)
have to do that maneuver with the cabs laying on their sides.

No loose binding posts yet...I want a pair of custom crossovers and WBT binding posts for under 1K
what issue are you trying to solve with the idea of custom crossovers ?
IF it's the highs are somewhat harsh, there is a much easier solution and cost next to nothing.
This has been addressed many times on this forum.
Your HF's are old enough that I almost guarantee that the foam plug is rotted. A normal problem
with 044's and 044Ti's.

Whatever you do don't let some "custom" builder talk you into them. That is a complex crossover and is specifically tailored for that driver set. If you change the voltage drive you will essentially ruin them. If the guy builds from the original schematic fine but don't go with a "Oh I can do better than that" If the guy uses the original network and plots the voltage drives and any modifications match the original voltage drive then you would be OK.No loose binding posts yet...I want a pair of custom crossovers and WBT binding posts for under 1K

from your tagline. I went the same route , picking up 18's as 044Ti insurance after buying the 250's. I didn't much care for their sound and they stay in their box (just, in case)
BUT then, I found some 120Ti's, cheap. They are likely the most undervalued JBL 3 way, 12 incher.
They've become my daily drivers, and IMHO the second best JBL 12 inch bookshelf (second only to the $5k Century Golds)
I put a fair amount of time into restoring the 120's and it was worth every minute.

You are better off googling the question

That is quite an insightful link of the whole topic. Interestingly it’s on Stero.net.au
