| 2x4 is a common size for acoustic panels and bass traps for many reasons, not the least of which is shipping cost. If they were taller shipping would get much more expensive. So many people make or buy 2x4 panels and install them in the corners. If you have 8' ceilings, then 2 of them stacked floor to ceiling is better. DOn't forget the room has 12 corners (or more). |
