Speaker Polarity Tester
The professional solution for testing speaker wiring and phase alignment. Accurate polarity detection in seconds for home theater, studio monitors, car audio, and professional PA systems.
What is Speaker Polarity?
Speaker polarity indicates whether your speaker is wired correctly. Speakers wired in reverse (out of phase) cause significant audio problems. This is the most common error in speaker installation and is easily corrected once identified.
Bass Cancellation
Out-of-phase speakers cause low frequencies to cancel, resulting in weak bass response.
Muddy Sound
Phase errors create destructive interference that muddies the overall sound quality.
Poor Imaging
Reversed polarity destroys stereo imaging and soundstage depth.
Reduced Quality
Overall audio quality suffers when speakers are wired incorrectly.
How It Works
Play Test Signal
Send the proprietary pop test signal through your speaker system
Hold Near Speaker
Position your device near the speaker being tested
Get Instant Results
Advanced DSP analysis displays polarity result instantly
The app uses advanced DSP analysis to determine if your speaker cone is moving in the correct direction, providing clear results with confidence levels.
Key Features
Accurate Polarity Detection
Industry-leading DSP algorithms analyze the acoustic waveform to determine speaker polarity with high confidence. Results displayed clearly as positive (correct) or negative (reversed).
Multiple Output Methods
Send test signals via built-in speaker, headphone jack, Bluetooth, or AirPlay. Connect to any audio system for testing flexibility.
Adaptive Speaker Analysis
Automatically adjusts analysis parameters for different speaker types including subwoofers, woofers, midrange drivers, tweeters, and full-range speakers.
Speaker Profiles
Save and organize your speakers with custom names, locations, and notes. Track test history for each speaker over time.
Complete Test History
Full log of all polarity tests with timestamps, results, and confidence levels. Export data for professional documentation.
Exportable Test Signal
Download the test signal as WAV or M4A to burn to CD, load on external players, or use with professional playback systems.
