Axiom may ber aware of a engineer Brian Ding and his tiny startup company called Rythmik Audio out of Austin Texas. He markets a unique subwoofer technology called direct servo. Among the DIY community Rythmik seems to have an outstanding reputation. And although I'm far from an electrical engineer, after reviewing his web site rythmikaudio.com I'm thoroughly impressed by the simplicity and elegance of his design.
I am sure Axiom could license this technology for a song (Ian are you listening???).
It's somewhat of a alternate technology, I think it could provide some excellent synergy with the DSP approach used in the 500/600. In fact it seems more sophisticated that static DSP in that it provides real-time servo feeback and by all accounts provides serious distortion reduction and extended frequency response.
And no I don't have the slightest connection to Rythmik, monetary or otherwise.
