Which inevitably leads one to wonder why would they offer a better sounding product for a 3rd party rather than their own. Wasn't it the other way around in the past when Stax OEMed for Magnavox?
They just alter the tension on the diaphragm by a tiny bit and the tonal balance changes completely. This is where the black art of ESL design really comes into its own as you have to balance a number of factors.
Stax did OEM work for a lot of companies and some were better built than others. It all came down to price though and the drivers were almost always the same so the real changes were how they were treated and the housings and their construction. None of them matched the SR-3 build quality but they were also a lot more expensive. With the Airbow it is a very limited product sold at a much higher price than any of the Stax offerings so I guess it's a win-win for both companies.
