Update to the room. I've been a very busy boy lately with a laptop in my back pocket and a new UMIK1 microphone. The sub used to be located here..\n\n\n I went location hunting to find a better spot for my little 10" sub using REW. I tired a couple of spots and wondered if the sub would sound better in the opposite corner behind the lazy-boy as shown here.\n\n\nI ran the measurements for each location and this what I found. \nThe red plot is where I had the sub before using REW to relocate the sub. The green plot shows the response with the sub at the new location.
