I was curious to know if anyone has the CSW Newton series MC400 or MC500. I currently have 3 MC300 across the front of my home theater system and 3 of their surrounds in a 6.1 setup with a Hsu VTF-2 Subwoofer. I'm starting to listen to a lot of music (mainly Jazz) and the MC300's sound great for home theater but really drop off around 110hz. I was considering upgrading the left and right front speaker. I don't feel like changing my entire system so I thought sticking with Cambridge because they are all timbre matched. Any suggestions?
