Speaker test tones: check selected frequencies by ear

By TechCompare · Updated · How we check

Use up to four fixed sine tones at a time to check selected speaker frequencies by ear. Change the tones manually to compare points across the range. Use measurement software and a microphone for a response curve.

Edit in the full tool

This tool plays up to four fixed sine tones at once. Adjust the frequencies manually and listen for changes, rattles, or room peaks at selected points. It is a listening check, not a continuous sweep or calibrated frequency-response measurement.

How this is calculated

Only four tones play at once, so the eight selected points here (100, 250, 500, 1000, 2000, 4000, 8000, and 16000 Hz) take more than one round. Play them individually or in small groups, then compare the left and right speakers. A continuous sweep or calibrated microphone is needed to measure a speaker's full frequency response.

Verdict

Use it for a basic listening check, such as spotting a rattle or a difference between selected frequencies. It can't sweep or measure the speaker's full response.

Frequently asked questions

Can this tool run a continuous frequency sweep?
No. It plays up to four fixed sine tones at a time. Change the frequencies manually to check selected points. A continuous sweep or calibrated microphone is needed to measure the overall response shape.
How can I listen for a speaker crossover issue?
Many two-way speakers cross somewhere around 2 to 3 kHz, but the exact point depends on the design. You can play fixed tones around that range and listen for an obvious change between bands. This is not a measurement of the crossover response.
