Volt VM752 vs VM753 mid dome difference

Can anyone tell me the difference between these two drivers?

Both are 75mm mid domes, but there appear to be subtle differences.

It appears the 752 has a larger diameter magnet than the 753, but the driver performancr specs are supposedly the same (for the 8 ohm versions). Not sure what the deal is here if there's only a physical difference and they compensated the magnet diameter with thickness.

They also list the VC assembly being different for both.
 
The magnet assembly looks different from they're pics (the 752 being less in height and wider)
But they are both listed to have a 200mm magnet.
The only spec difference, except from the obvious from 16 vs 8 ohm. is that the 752 has 50 hz lower fs.
The 753 is slightly lower in price, and under some conditions might allow a little closer spacing of drivers.

And if your looking for a 3" dome and not in a hurry time wise,also look at what Bliesma has announced to come out this year 🙂
 
AOS in Germany has a custom version with a different WG profile of the VM753 and is available in 8 and 16 ohms. The VM752 is also listed as 8 and 16 ohms.

So it does look like Bliesma is cooking up something big...
