I use JBL ScreenArray speakers for LCR and use JBL Studio L810 consumer speakers as surrounds. (I needed a maximum speaker depth of 5" for surrounds and there were not many to choose between). I do sometimes feel that the surrounds lack the dynamics in movie scenes with many discrete effects, but this is only when I play at reference level. IMO you do need some DSP/EQ to timbre match the LCR and surrounds though.
