Onslaught

Hello, I was looking around but can't figure out if center speakers are still magnetically shielded or not? I doubt with modern TV's that it's nessesary and figured that they no longer make them? I'm building a video game room with both a modern OLED and a Sony wega CRT TV for my retro stuff. I don't want to buy a modern speaker if it will affect my old CRT TV.
