Like all things depends on volume and type of music .... With lower ceiling height I think will be fine up to 80db for extended listening .... I had the 30.1 in my listening lounge 7mx5.5m X 3.6m high but didn't quite work so bought big tannoy Arden's which fill the room and even work better at lower volume. My new thesis is bigger is better always if you can ......
