Скачать или смотреть Speaker Phase & Polarity Test 🔊 Fix “No Bass” & Hollow Sound (1 Hour)

Does your sound system feel weak, hollow, or completely missing bass?
Your speakers may be wired OUT OF PHASE.

This professional Speaker Phase & Polarity Test instantly reveals wiring mistakes, polarity errors, and bass cancellation problems in any sound system.

🔊 HOW THIS TEST WORKS
0:00 – IN PHASE (Correct)
You should hear strong, focused bass in the center. Vocals sound solid and stable.

0:05 – OUT OF PHASE (Wrong)
The bass collapses. The sound feels wide, empty, or far away. This means one speaker is wired backward (+ / - reversed).

⚠️ IMPORTANT
If you listen on a phone, laptop, or mono Bluetooth speaker, the OUT OF PHASE part may become completely silent.
THIS IS NORMAL.
It proves the test is working correctly. When left and right are opposite, they cancel each other in mono.

🎧 For best results use HEADPHONES or stereo speakers.

📉 WHAT IS PHASE CANCELLATION?
When one speaker pushes air while the other pulls it, sound waves destroy each other. This removes bass and ruins stereo imaging.

Perfect for:
Car Audio • Home Theater • Hi-Fi • Soundbars • Headphones • Studio Monitors
