I just bought my first RPTV HDTV-ready Sharp 55" widescreen set. I have set everything up including two large speaker cabinets consisting of a 15" woofer, midrange and tweeter. These speakers are not shielded, but due to room restrictions MUST be placed next to the new TV. I have never had a problem with these speakers in the past next to my 27" Toshiba, but I am suddenly paranoid they could damage my new TV. I have them about 10" away from the set now, but was wondering if I could construct my own video shielding to install in the speaker cabinets. Is this possible? What material would you use? How do I do it?
