Treatment Recommendations
Bass Traps
Place in corners where modes are strongest. Minimum depth for 34 Hz:2.50 m
Listening Position
Avoid 50% room length/width (null points). Sweet spot at 38% from front wall:1.90 m
First Reflection Points
Add absorption at side wall reflection points, approximately 1/3 room width from front.
Diffusion
Effective above Schroeder frequency (189 Hz). Use on rear wall and ceiling.
