Q I own Paradigm Monitor 11 speakers and an 80-watt powered subwoofer. The speakers are set up in my living room 6 feet out from a sliding glass door. What type of acoustic treatment product should I put up behind the speakers to improve their sound? Should it be foam or something more solid? —Jon Cotton / via e-mail

Got tech questions? Looking for advice on how to get the most out of your A/V gear? The experts at Sound & Vision have answers! Email your questions to AskSandV@gmail.com.

Welcome to UAV's latest blog, in which I answer your questions about anything related to audio and video technology—equipment setup and optimization, wired and wireless connections, room environment, content creation, digital cinema, cable/satellite/terrestrial broadcasting, online streaming, Blu-ray, 3D, 4K, future technologies, and anything else in the ever-expanding A/V universe. Even better, other readers can add their two cents in the comments, which I invite and encourage—after all, you might think of something I didn't. Also, I know a lot about this stuff, but I don't know everything, so sometimes I'll post a question and throw it open to readers who might know more about it than I do. And if an answer I provide proves to be inadvertently incorrect or misleading, I want to know, and I'll update it immediately.

All you have to do is send your question to askscottwilkinson@gmail.com. Try to keep your questions as short as practical, but don't skimp on any details you think are important for me to provide a suitable answer. If you're asking about specific gear, please include the makes and model numbers.

My goal is to help you get the most out of whatever A/V system you have and better understand the complex world of current and coming technologies. So let the questions begin!
