Well, if I read it right, 35hz was the bottom end for the bigger one. I feel like that would be quite a stretch to get down there. I do agree with you though on the distributed audio thing. These would be a great addition to in ceiling/wall speakers for music. Most HT would turn away probably. Thanks for sharing this. Nice to see different things.I have the same thought... I wonder, if you place four in a room (corners), would they benefit form room gain and affectively dig down into the 20 Hz range?
