Bass Response Test

Test your audio equipment's bass performance from 20Hz to 250Hz

⚠️ SPEAKER SAFETY WARNING

Start at 20% volume or lower! Bass frequencies can damage speakers and headphones at high volumes. Always test at low volume first, especially sub-bass frequencies below 60Hz.

This test can produce powerful low frequencies that may damage your audio equipment if played too loud.

Bass Frequency Safety:

  • • Sub-bass (20-60Hz) limited to 30% max volume
  • • Deep bass (60-120Hz) limited to 40% max volume
  • • Start testing at 20% volume or lower
  • • Increase gradually while listening for distortion

Understanding Bass Response

Sub-Bass (20-60Hz)

The deepest bass frequencies that you feel more than hear.

  • • Movie explosions
  • • EDM drops
  • • Pipe organ pedals
  • • Thunder rumble

Bass (60-120Hz)

The main bass range that provides punch and impact.

  • • Kick drums
  • • Bass guitars
  • • Hip-hop bass
  • • Male vocals (low)

Upper Bass (120-250Hz)

Adds warmth and body to music.

  • • Snare drums
  • • Guitar body
  • • Piano lower notes
  • • Vocal warmth

What to Listen For

✓ Good Bass Response

  • • Clean, undistorted low notes
  • • Tight, controlled bass hits
  • • Even volume across frequencies
  • • No rattling or buzzing
  • • Clear pitch definition

✗ Common Bass Problems

  • • Boomy, muddy bass
  • • Missing sub-bass
  • • Distortion at high volume
  • • Port noise (speakers)
  • • Rattling enclosure

Testing Tips

  1. Start with low volume - Bass frequencies carry more energy
  2. Listen for distortion - Increase volume gradually until you hear distortion, then back off
  3. Check your environment - Room acoustics greatly affect bass perception
  4. Test different positions - Move around the room to find bass null points
  5. Use the sweep test - Identifies frequency response dips and peaks

Bass Performance by Equipment Type

In-Ear Headphones

Limited by small driver size

  • • Often weak below 50Hz
  • • Good seal critical for bass
  • • Bass boost common

Over-Ear Headphones

Better bass extension possible

  • • Can reach 20Hz in quality models
  • • Open-back typically less bass
  • • Closed-back better for bass

Bookshelf Speakers

Size limits low frequency output

  • • Typically roll off below 60-80Hz
  • • Port design affects bass
  • • May need subwoofer

Subwoofers

Dedicated low frequency reproduction

  • • Specialized for 20-120Hz
  • • Room placement critical
  • • Integration with mains important
