There have been a good following on planars among audiophiles. I think I understand them now. Planars are really good and provides a more realistic sonic characteristics (less distortions) at certain frequencies and with certain trade-off (normal for any speakers in consideration).
The discourcaging issue with most planars are their low sensitivity (you need high power amplification), and some frequency response limitations and issues.
However, BG have patented designs that almost met the challenges of previous planars. However, I think planars will be planars, in terms of how it reproduce sounds. As the specs have described it, the height of planar sound will be the length of those planars (controlled vertical), but its horizontal propagation is not an issue (wide dispersion) depending on frequency.
So, If you want width & height to your sound, you have to build high planars (for whatever it will serve you). In a hotel or lounge, BG design tall planars to remove issues of people listening (either standing up or sitting down, regardless of their ear-listening height). In home, if you are into critical listening always (presupposes sitting down position), tall planars may not be a necessity at all.
