Newbie trying to get better quality vocals at home. I have the gear, I just need advice on how to set up. The space is basically open, as it is a small dining room that opens up to a larger living room and has a doorway (with no door) to a kitchen. That may itself be the problem.Terrible echo. I have 4 corner bass traps, 3 roughly 4' by 2.5' foam squares, an SE Electronics RF-X reflection filter. How should I position them? (Mod edit: dead links removed) Note the square above 10 ft wall is small window, wall separates kitchen from room i would like to use but doorway does not have closing door.
