The Demo Theater presentations are often made in an environment with a high level of ambient noise. That, in conjunction with the presenters being seated and therefore not projecting as well as standing, results in the audience in the rear having to strain to hear the presenter. The sound system is set up with two loudspeakers in the front. I suggest having another pair of loudspeakers halfway back to help the audience at the rear of the space hear the presenter.
Thanks for the feedback. Experimenting with demo theater setup is an ongoing project. Having a pair of speakers halfway back, or perhaps all the way at the back angled forward is something we'll arrange.
