Trying to get a 5.1 monitor for orchestra music production. Listened 4328 and sounds really nice , not so bright as Genelec. Anyone compared the sweet spot of 4328 5.1 , 6328 5.1 and other systems like Focal or blue sky? Any 4328 and 6328 users here? How big or small the sweet spot is, for the 5.1 setup?
