Is there an "inherent" problem with radical toe in, when the main sound from the front drivers cross in front of the listener, instead of the more conventional setup where the crossing point is behind the listener - and if so, what?
@o_holter Toe-in helps you to minimize side wall reflections, which are interpreted by the ear as harshness. I don't think there is a 'more conventional setup where the crossing point is behind' for this speaker. Generally if there are side walls nearby, that might not work out so well.
