Thanks for the comments! Sorry, ment "ceiling", the images show room and locations (black arcs in the living room). White boxes are the sub bass matrix (one more is added, now four).
I think CBTs in the favour of Don and Bjorn are the perfect everyday leisure-listening speakers, since thy actually work in a large room where you walk around, and can also be placed in positions that the usual omni-low/directional-high sounds really lousy, like my placements. Very girlfriend-friendly
Roof-mounted, they also take up virtually no space.
Some think they're ugly. I'd like to make a case they're not. Adding some images from my previous apartment too. These should be a huge commercial success, if normal people ever got to listen to them. My girlfriends son have, he's 23, a typical "bass head", and listens mostly to electronic like techno; he's completely baffled and absorbed by the sound. They play these very transient tight artificial sounds in a way no other speakers I've heard; enormously wide, and tightly controlled, considering the listening space and placement.
I'll report how it goes
