Precision frequency sweeps designed to reveal speaker performance.

Check Your Speaker Sound Quality

Test your speakers with precision frequency sweeps. Check bass response, full range clarity, and left/right channel balance. Free, instant, no downloads.

What Each Test Does

Test Frequency What it checks
Bass Test 20 - 300 Hz Low-end response, woofer health
Full Range 20 Hz - 20 kHz Entire audible spectrum
Left / Right 440 Hz tone Stereo wiring and balance
Music Test Full spectrum Real-world playback quality

Bass Test (20Hz - 300Hz)

The bass test sweeps from 20Hz to 300Hz, testing how your speaker handles low frequencies. Listen for smooth, even output. Rattling or buzzing can mean a damaged woofer, loose enclosure, or the speaker just can't go that low.

⚠️

Watch your volume. Start at moderate volume. Bass frequencies push speakers hard. If you hear distortion, lower the volume before continuing.

Full Range Frequency Sweep

This sweeps the entire audible range from 20Hz to 20kHz. It reveals dead spots, resonances, and roll-off points. A healthy speaker should produce a smooth, continuous tone without sudden jumps, gaps, or harsh peaks.

Band Range What to hear
Bass 20 - 300 Hz Deep, full, no rattle
Midrange 300 Hz - 2 kHz Clear vocals, instruments
Presence 2 - 8 kHz Detail without harshness
Treble 8 - 20 kHz Airy, no sibilance

Left / Right Channel Test

Audio alternates between left and right channels so you can confirm each speaker is wired correctly. If sound comes from the wrong side, your speaker wires are swapped.

Do this

  • Sit centered between speakers
  • Test at moderate volume
  • Check both channels respond
  • Swap wires if channels are reversed

Avoid this

  • Test with only one speaker on
  • Skip the balance check
  • Ignore volume differences between sides
  • Move speakers during the test
💡

For the most accurate results, sit centered between your speakers at ear level. Remove any obstacles between you and the speakers.

Common Speaker Issues

Symptom Likely cause Fix
Rattling on bass Loose driver or debris Check screws, remove objects

Muffled / dull sound Blown tweeter Replace tweeter or speaker
Distortion at volume Overpowered driver Lower volume, check amp
Uneven left/right Balance setting off Adjust balance or swap wires

When troubleshooting distortion or rattle

Frequently Asked Questions

How do I test my speakers online?

Pick a test (bass, full range, or left/right), set volume to moderate, and hit Start. Listen for smooth response without gaps or distortion.

What frequency range should speakers cover?

Full-range speakers should hit 20Hz to 20kHz. Smaller speakers might struggle below 80-100Hz, and that's totally normal.

Why does my speaker rattle during the bass test?

Usually a loose driver, damaged cone, or objects vibrating nearby. Try lowering volume first to rule out over-excursion.

How do I check if speakers are wired correctly?

Run the Left/Right test. Sound should come from the correct side. If it's reversed, swap your speaker wires.
