Bass traps: what they do, where they go, and what to avoid
Tight low end is a design problem. A simple guide to corners, rear walls, and the biggest myths.
When bass feels boomy in one spot and disappears in another, you’re hearing room modes and boundary buildup. Bass traps don’t ‘add bass’ — they make bass more consistent.
Why corners work
Low frequencies build up at boundaries. Corners are where multiple boundaries meet, which concentrates energy. That’s why trapping there tends to be the most efficient.
What to avoid
- Relying on thin panels to solve deep bass issues
- Random placement (coverage without purpose)
- Ignoring the rear wall when seating is close
A practical starter plan
- Trap at least two front corners
- Add a rear-wall absorber if close to the wall
- Then measure or listen and decide where to add next
