Click any test button, set your volume to a comfortable level, and listen. You'll hear test tones through your speakers instantly — no download required.
Our speaker test uses the Web Audio API to generate test tones directly in your browser. All audio is created locally, nothing is downloaded or uploaded.
Select a quick test or use the tone generator for custom frequencies.
Start at low volume to protect your speakers and hearing.
Check that both speakers play correctly and sound balanced.
Use the frequency sweep to test from 20 Hz to 20 kHz.
Click the "Left" button to play a 440 Hz tone through your left speaker only. Then click "Right" to test the right speaker. If sound comes from the wrong side, your speaker channels are swapped — check your cable connections or audio settings.
The left/right test uses the Web Audio API's StereoPannerNode to route audio to a specific channel. A pan value of -1 sends audio to the left speaker only, +1 to the right speaker only, and 0 plays through both speakers equally.
Human hearing ranges from 20 Hz (deep bass) to 20,000 Hz (high treble). Most desktop speakers cover 80 Hz to 20 kHz, while speakers with a subwoofer can reach as low as 20–40 Hz. Studio monitors like the Kali Audio LP-6 typically cover 47 Hz to 21 kHz.
Here's a breakdown of frequency ranges and what they sound like:
Use the Bass Test tool above to play frequencies from 20 Hz to 250 Hz. Start with the "Bass (80 Hz)" preset and lower the frequency gradually. Note where you stop hearing or feeling the bass — that's your speaker's low-frequency limit.
Small desktop speakers typically can't reproduce frequencies below 80–100 Hz. If you need deep bass for music production or home theater, consider adding a subwoofer like the Kali Audio WS-6.2.
Yes, playing extreme bass frequencies at high volume can damage speakers. Low frequencies require large driver excursions, and pushing small speakers beyond their limits can cause distortion, voice coil overheating, or physical damage. Always start at low volume and increase gradually. We are not liable for any damage caused by using this tool.
Signs of speaker distress include rattling, buzzing, or distorted sound. If you hear any of these, reduce the volume immediately.
Check your system volume, verify the correct output device, check cable connections, try a different browser, and update your audio drivers. These five steps fix most speaker issues.
Make sure your system volume is turned up and not muted. On Windows, click the speaker icon in the taskbar. On macOS, check the menu bar volume slider. Also check the volume controls on your physical speakers if they have them.
Your computer might be sending audio to the wrong device (headphones instead of speakers, or an HDMI display). On Windows: Settings → System → Sound → Output. On macOS: System Preferences → Sound → Output. Select the correct speaker device.
Ensure all cables are securely connected. For USB speakers, try a different USB port. For 3.5mm speakers, make sure the plug is fully inserted into the headphone/speaker jack (usually green). For Bluetooth speakers, verify they're paired and connected.
Some browsers may have audio playback issues. Try Chrome, Firefox, or Edge. Make sure your browser isn't muting the tab — look for a speaker icon on the tab. Also check if any browser extensions are blocking audio.
Outdated audio drivers can cause sound issues. On Windows: Device Manager → Sound, video and game controllers → right-click your audio device → Update driver. On macOS, audio drivers are updated through system updates.
If only one speaker works, try swapping left and right cables to determine if the issue is with the speaker or the cable. If no sound at all, test your speakers on a different device (phone, another computer) to rule out hardware failure.
