I am in the "how do I make my room quieter stage of building my home theater. I have a window to deaden and standard room treatments but now I am faced with one noisy scren case. It is a 119" Da Lite HP pull down with black case that I ordered from Jason Turk at AVS. For the most part I am thrilled with the screen, but, I have noticed some ringing from the screen and when I clap my hands I can hear it ringing. I am going to eventually paint the ceiling to match the rest of the room ( just lazy more than anything I have the supplies) and hang a black velvet valance in front of it because the screen is rather reflective ( visually as well). I thought about getting some of that peel and stick stuff the car guys use, would that work here? And or would it void the warranty? Any cheap (free) tips to start with? My HT budget is in the dumper right now, I have not bought a new movie for about 2 weeks!
