Off-axis response of this driver is absolutely crazy. 0-30° with pretty much no difference, at 60° the frequency drop just about compensated bafflestep on my 6cm wide test enclosures (so at this angle I got a flat-ish frequency response) and at 90° (!) it lost 14dB at 18kHz, compared to on-axis. And it did it in a very controlled way. So 180° radiation claimed by TE is not just some marketing BS, this thing can really do it.
It's usable from...

It's usable from around 200Hz, so definitely not a standalone fullrange driver, but combined with a woofer, it can do wonders.
