Have you noticed any audio differences, other than needing to adjust trims / recalibrate? Do you toe in L/R? I'm very happy with my v6, and my speakers are just a couple of inches behind the screen with L/R toed in maybe 20d. Seriously considering upgrading to v7.I don’t have any of the V6 material around any longer, but the V7 material seems to have a smoother front. Honestly if I did not tell someone it’s accousticly transparent they would think it’s a traditional screen. The material when stretched looks smooth as silk.
