Just a drive-by comment here, but if comparing the woofers to see about compatability, if it is the connectors that are holding you back, you can certainly find new ends for the wires and solder/crimp/heatshrink them on. the newer woofer's spade connections ARE different widths (and lengths) from each other, but also (as you noted) different than the older woofer you are looking to repair/replace.
Repairing a speaker isn't impossible by any means, but like Socky mentions, it can become a can of worms if you have never done it.
As for Axiom support, the biggest thing lately seems to be long delays in responses, not that they won't help people out with great service, just that things are slow going lately... VERY slow going. Be patient, and they will offer solutions to your problem.

The Thiele-Small parameters for those two drivers are not equal. Obviously, by just looking at the two drivers, you can tell FS, VAS/CMS, VD, MMS, XMAX/XLIM and SD are not equal...LOL! I'd be very careful if I were you. If you replace the old driver with the new one, you might alter the flux quantization within the magnetic gap and cause your entire house to get sucked into never-never land .

Well, I heard back from Axiom and now have pricing for a new driver. In the mean time I decided to experiment. I moved not only the M3's woofer, but it's tweeter and crossover as well. Drivers from the M3 are ever so slightly larger, so the seals around the speakers are not quite perfect. The result? In a word, horrible. Detail is reduced, bass is gone. Double checked that it's not a wiring issue. It's probably due to crossover tuning. In fact it almost sound like my M3s, which never worked very well in that room. Undoing now. Very different crossovers in the two speakers. The woofer is directly powered in the M40 (on the left), the tweeter has a resistor and two electrolytic capacitors which are not board mounted: Can also now confirm that my M3v3 is completely veneered on the inside, almost makes it look like plywood if you don't look at the speaker cutouts!

how bizarre. Can they provide an exact replacement driver?

Veneer on the interior will change the speaker's response.

AFAIK the woofer has always been directly driven on M3/M40... and at first glance that still may be true. The crossover on the right (assuming that's from your M3 ?) only seems to have one additional capacitor, so it's likely that the woofer is still directly driven. Might be worth tracing out the circuit, probably just a one layer PCB...
Definitely if the cabinet doesn't seal that is going to mess up your bass pretty seriously.
If you lived a bit closer I could drive over with my M40s and try some mixing & matching, but Richmond is a fair haul even without the hassle of going through customs.

Yep... first thought was "hey he's in Canada too, no customs/immigration" but that didn't last long.
Besides, IIRC the fastest route out west is supposedly cutting through Michigan anyways, even with two trips through immigration. I guess the trick is to cross the border at the smaller crossings where you don't have 8000 trucks lined up ahead of you.
