Greetings! I'm in the process of expanding my studio to 5.1, and wherever I look for wisdom it is highly recommended to have three monitors of the exact same make and model for the LCR channels. In my case, due to space constraints an MTM center is optimal, and due to budgetary constraints I'm looking at standard left and right monitors. So I've narrowed it down to my only real option, the Eris series, and was just wondering if these speakers share a similar enough frequency response to translate well in cinema and music? I suppose the question would also apply to mixing E8 XT's with an E66.
