What Will You Test?
Test Subwoofer Response
Before: Your subwoofer sounds boomy or thin, but you don't know which frequencies are the problem.
After: Sweep through 20-200Hz. Hear exactly where your subwoofer performs best and where it struggles.
Find Room Resonances
Before: Your room has boomy bass in corners or dead spots where bass disappears.
After: Low frequencies reveal room modes. Note where volume jumps — those are resonances to treat.
Optimize Subwoofer Placement
Before: You placed your subwoofer randomly and hope it sounds good.
After: Run the test, move the subwoofer, run again. Compare response at different positions.
