Back in 2007/2008 I purchased James Loudspeakers for my home theater. I have since moved and stored them. They haven't seen the light of day since 2014. I have the following: 1 - EMB 1200 sub 3 - 805 SDX's 4 - 62 SDX's This may be a silly question but in my new house, I am considering building a theater in my basement and using these. Since I have been out of the theater world for a while, has speaker technology changed enough that I shoudl consider new loudspeakers? Thank you.
