What Will You Test?

Subwoofer

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.

Room Modes

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.

Placement

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.
