Interview with Woody Norris, inventor of HyperSonic directional audio systems

I’ve only used Sennheiser directional systems which weren’t too impressive, so the jury is still out on the grand claim that these speakers are the biggest breakthrough in playback since the invention of the loudspeaker. The politics of frequency involved in these hypersonic speakers is a whole other issue – the sennheisers were some of the most painful speakers ive ever come across – piercing ear pain and a full body migraine within minutes ; )
