The BMR has very wide dispersion due to the modal way it works. I would love to see Amir measurement a speaker using one. A friend of mine was one of the development team and has designed several for different clients. The difficulty is hf consistency since the surround, necessary for the seal at lower frequencies, is difficult to make accurate enough and cheap enough for consistent edge performance at very high frequencies.doesn't look like it tries to control diretivity like several of the higher scoring speakers here do.
