It says "difficult or impossible"; it doesn't mean impossible... Can you edit the section and augment it with comments and links to articles?

But is this because of its higher frqeuency components? In an article I mentioned earlier ("Spatial auditory display using multiple sub-woofers in two different reverberant reproduction environments"), tests were made in an anechoic chamber where the detection was much better than in a small room. The test tones were one octave wide with centre frequencies varying between 40Hz and 100Hz. Would such tones have high frequency components in an anechoic chamber?

Dipole and cardioid subs excite less room modes than omni subs: http://www.kirchner-elektronik.de/~kirchner/DIPOL-CARDIOIDeng.pdf http://www.linkwitzlab.com/Woofer%20accuracy.rtf Would they be a better choice for Ambisonics?

I understand that with ambisonics bass management is not required, although a dedicated decoder for 3 or more subs could be considered like bass management (when full range speakers are not available). > Interesting thread.
