So thanks to a forum member I was ablessed to get the speakers back in action. I now even have a spare. This forum rocks.

I'll find out how big a deal this really is, soon (104H vs 104H-2). That hole in the 240Ti cab ain't gonna fill itself...From what I have read on this forum, that would require a major crossover redesign and possibly an mid enclosure change as well.
So, comparing the plots on the ol' le5 matrix thread, my initial thoughts are to increase the 240Ti MF section attenuation some 3-4dB,
shift up the LPF rolloff to a higher freq (no longer using or compensating for a significant rising response), and -maybe- tuck
the level down a bit at 1.8KHz (shallow notch). Will have a listen and a measure first.
LOL, so I sent a message to Harman asking a question about a 240Ti part (screw for 044Ti, P/N 61145) and got this:

Now I know why they send people here.
So... 044Ti takes a 1 1/2" 8-32 screw.
and in a 240Ti, without being able to A/B the 104H and 104H-2,
I'm in no rush to modify the 104H-2 swap.
and yes, black oxide hardware is being ordered, now that I know the size.
Looking good! Wonder myself how the 104H-2 will sound as well since they are more easily procured.

I'd like to compare... listening and measuring, but have no 104H to try.
I did look at the published response curves though, and there are differences in both sensitivity and response. I cranked out a "fix" in Spice, given the FR and imp curves, but haven't tried it yet.
So, being itchy to hear something, I tried a straight swap anyway (no xover mods), left both mid and tweeter switches at 0dB (vs -2dB), and it doesn't sound "wrong"... maybe a bit bass heavy in the 60-80Hz range, but that could be where I have them or by design.
I did try the 2dB mid switch position, which seemed like a logical first cut given the sensitivity difference, but it sounded like a scooped EQ, so back to 0dB until I can be bothered to get out the test gear and see what's going on (compensating for the bass by boosting the mid(?). May have 044Ti's with gooey foam too, but one issue at a time
