Re: [Sursound] OT Stereo stage width - Was: Static stereo source in rotating soundfield, possible?

[David Pickett]

The problem with speakers at +/- 45 degrees is that one needs a wide 
room if one is to sit at a decent distance from them.  However, it 
can be impressive.  I have found the effect even better if a centre 
speaker of the same typeis added.  Gerzon gave the ratios necessary 
for matrixing 2 channel stereo into this 3 channel format.  It is not 
simply a question of feeding the centre speaker with a -3dB sum, but 
quite easy to implement.
