The audio signal is fed directly to the servo motor,which turns back and forth depending on polarity,driving the cones via the belts.

"Interesting, I just assumed it was the same as the Contrabass."
It is, just the nomenclature is different. In the blurb on the Contrabass since it is a vented direct radiator system the vent substitutes are 18" passive radiators and the 15" passive radiators driven by the S shaped belt are called 'the active radiators'.

Hmm, I guess I can't 'see the forest for the trees' because I'm looking at an assembled CB belt drive system and I wouldn't describe the belt drive as 'S' shaped or the stabilizer belt system as idler pulleys.
Oh well, it's academic since Don's posted something with a drawing of it. Thanks for clarifying the BT7 uses the same system if not the same parts.
