I have 2 stereos in my living room. One is a home theater 5.1 and the other is an old school 2 channel. I want to keep my front speakers from the theater on top of my large speakers from the 2.0 stereo. Is this OK? All speakers are magnetically sheilded, but with the small front speaker being so close to the voice coil on the large speaker, I am concerned about disrupting the magnetic field. Can I harm the speakers in this way? Will sound quality suffer?
