All interesting!
Don`t know how beaming sounds like, so can`t say on my 2360`s...
It may be hard to hear indoors with all the reflected energy most rooms have but as you walk off axis at some point you will hear the HF drop dramatically, like someone turned it off.
You may have to drag one outdoors to really hear it.
