Bachmann speaker question

I have seen the below discussion in another forum but cannot find anything here on this issue.

Has anyone used non-cone/magnet speakers with a TSU?

I've heard a rumor that Bachmann has a loco coming out near the holidays which
(somehow) uses the cab shell as a sound resonator (ie no traditional speaker)
coupled to an OEM TSU. They aren't using the cab as an enclosure for a speaker
according to the rumor.

Based on a response from the Bach-man on Bachmann's board last night, I believe
they are using a device that will induce vibration into the cab. "Exciter" was
the term used. Googling a bit - sound exciters or tactile transducers - use

I checked the forums but did not see anything in the subject lines but I have missed things before.

Any thoughts?

Thanks for the reply. Probably would have taken a time to find. I  did a couple speaker searches but came up empty. Probably did not dig deep enough.
