I've seen a few pictures of producers using their speakers sideways. Specifically Yamaha's. I have HS7's and was wondering if there's actually any real benefit to this?
Overall you will end up having phasing problems if your monitors high freq tweeters (Ive no idea whats the name lol.) are designed to be in vertical position. We have a pair of Genelec 1031s at school in horizontal atm and the sweet spot is _very_ narrow - if you move your head 30 centimeters, stereo field goes all nuts and you get a bunch of phasing going on. But as said depends on the monitors, room etc.
