I used four sets of Logitech 5.1 speakers (leaving out the centre speaker) for a young friend's Masters final major project at Bath Spa University earlier this year and the results were stunning - they were arranged as upper and lower octagons using 3rd order amb. for direct audio and 1st order amb. for convolution reverb (in the b-format domain using York Uni impulse response of York Minster) - all the software was in Max/MSP and used the ICST externals.
The speakers were helped by the active bass management in the accompanying subwoofers (all 4 of them) _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
