This video explains how the polarity of speakers, microphones and amplifiers are defined and the importance of maintaining polarity consistency during sound recording and reproduction. Then it demonstrates how to test the polarity of them using a computer with a sound card and Multi-Instrument.

It's clear to me now. Thanks for the vid!
My old pal told me that he played there recently. I've never heard of online gaming before. He likes it a lot. I think he wants me to read about baccarat guide bonuses. It's gonna be fun there.

Hi...i am a new user here.One way to test phase is to use a battery. This works for woofers and subwoofers. If the +ve terminal of the battery is connected to the +ve terminal of the woofer the cone will move out and if the +ve terminal of the battery is connected to the -ve terminal of the woofer the cone will move in. This can allow you to ensure that your subwoofers and woofers are electrically in phase. However since your subwoofer is usually in the trunk and your woofer is generally in the front door you may have to shift the phase of the subwoofer so that both woofer and subwoofer are acoustically in phase.

calculate percentages
