Actually, He HAD already split off and started his own company by that point.. the controller box DID say Meyer (not sure if it was Labs or Sound Labs, though..)..
As far as the boxes going to 30 Hz.. I ended up running sound from some researcher that had a lecture hosted at the SF in Union Square. The playback was SO low the standard SM4's weren't going to cut it.. so we ended up using a single JM3 inside that small meeting room - sort of analogous to a elephant piggy-backing on a dog - and I was "chosen" one to go and do this. Most of the stuff he had WAS indeed sub-40 hz.. and the JM-3 had at least enough to make it sound believable down there. Good thing they weren't screaming for more than 90 db C weighted though..
And I bet the group in the next room over got a good massage out of it..
That.. and the JM Sub.. were the reason I am doomed to spend my life building and enjoying subs..
Best,
