Hey, I don’t post often but I have to talk about this speaker. Really blown away for what they can do. That fat juicy Altec midrange sound in a large bookshelf speaker. I prefer them to my Altec Seville’s. Driving them with my Radio Craftsmen C 500’s and seems to be a perfect fit. Have to be honest the RC’s make every speaker I’ve thrown at them sound better, if they are efficient enough. Been listening to them for a few hours now. We all known what that means.
