I'm stuart.
The resistor change for the tweeter on the Aucoustica website refers to the change you need to make if you replace the TC90k with a TC120TD5 due to it's increased sensitivity. In my opinion the TD5 is a far superior driver than the TC90K - no harshness at all but it does require a good bit of experimentation to get the correct value resistor.
I have heard of some people just removing the parallel tweeter resistor and swearing by it but it's not something I tried.
I owned H2's for about 13 years and then Ta'us - the Ta'us are better, no doubt. They're both good speakers but if you're buying a pair be diligent. The foam on the mids and the bass will rot over time so inspect them very closely before buying. A few years ago HiFi Collective got a batch of Seas MCA11's made so replacement drivers may still be available. Replacement bass drivers might be able to be found under a pile of hen's teeth. Replacement surrounds are available for the mids and bass.
If you are going to get Paul to do his magic just be aware that what you have after he's finished aren't H2's - other than the cabinet everything else get's changed (I'm sure he'll do whatever you want to the speakers so retaining the original drivers may be an option he offers).
The Ta'us, which replaced the H2's, has a slightly modified crossover for the tweeter which did improve their sound, gave the upper frequencies a bit more focus.
Here's Martin Clark's drawing of the crossover with my notes:
[IMG][/IMG]
Garrard 401, Jelco 750 with Shuggie, Ortofon 2M Black / ZYX Yatra 100, Project Phono RS with Sigma22 Linear PS, RPi3 + DigiOne + Linear PS, RPi3/1Tb SSD with PiCorePlayer + Linear PS, Perreaux Eloquence 250i 40th Anniversary with ES9038Pro DAC, DCG3 Pre-Amp, Neurochrome 8x2 Pre-Amp, Neurochrome 686 Power amp, Benchmark DAC2 HGC, Primare V25 CD player, Monitor Audio PL300, Sjostrom DCT03 DC Blocker.
Another +1 for the Impulse H2’s.
Astonishing sounding things, but huge boxes and subjectively (imo) quite old fashioned looking.
Currently working on my custom “Modern white version” set, repaint and refinish, refoaming the bass drivers, upgrading internal crossover wiring, fitting new white speaker cloth and fitting external outrigger feet.
Should look a lot more modern.

they are spellbinding to listen to
ou might slip, you might slide, you might
Stumble and fall by the road side
But don't you ever let nobody drag your spirit down
Remember you're walking up to heaven
Don't let nobody turn you around
… Walk with the rich, walk with the poor
Learn from everyone, that's what life is for
And don't you let nobody drag your spirit down

Crikey!
Thanks for the info fellas, I have a lot to think about.
In the meantime (yes, since yesterday) I have put the money into an investment so I'll reconvene my thoughts (and all of yours) pending the outcome of that investment.
