Angie’s room (American Sound) has those horn speakers that were pretty damn amazing. Seeing Angie tapping her foot and feeling her own music is always fun too, haha.
Regarding the Bach demo room, I feel the room does not do it much justice as only a very singular sweet spot can experience it. There was literally 11 people in the room and only one person can experience most of its effects due to how set up is based around 1 person. I could tell the remaining other 10 people were a bit annoyed as they all wanted to see what it’s about. The demo person did mention that had room been larger, effects would have been displayed easier.
