Room Treatment Help
I just moved to the DFW area and drew the short straw for the wife assigned small 10 x 12 x 9’ soon to become, dedicated listening room. It’s in dire need of treatment as there’s a weird resonance, echo sound when clapping your hands. I’ve tried LRS + and open baffle speakers (Spatial Audio Lab) with a nice tube pre and both tube and ss amps. I’m just not happy with the room acoustics. I know I need help and realize small rooms are inherently tough to get good sound. My question is, where in the world do I start? GIK, Primacoustic, Acoustic Fields (Dennis Foley- this guy makes sense) etc? There are tons of YouTube vids out there, I’ve probably watched most of them but the topic is as confusing as trying to come up with end game components for an audiophile. Thanks in advance for your thoughts and experiences as they are highly appreciated!
