So maybe the motor shaft turns back and forth. anyway, thanks again for the pictures djk.🙂

The audio signal is fed directly to the servo motor,which turns back and forth depending on polarity,driving the cones via the belts.
Page 2 of this link shows a diagram of how it works.

"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.

any additional info with the BT7? How about the internal and external dimensions of the box? Does anyone have this info?
