My converted bedroom (10x9x8) sounded like cr*p. It was just awful. I called GIK and sent them pictures of my room. They made several suggestions which I incorporated into the room. It was transformative. My room, despite its dimensions, now sounds very, very good thanks to GIK. I recommend them highly, not only for their good advice, but for their excellent quality and affordable products.
How do you know what room treatments to use?
I am thinking improving my system with room treatment. My system sounds “loud” (distorted?) when turned up. It is a high resolution, very good $100K system built over several decades. I am getting a new preamp that will improve things but think that the room is significantly to blame. How can I actually tell what is amiss and what is needed?
