Easy to make sure both speakers are in phase in a stereo pair is to use a D-Cell battery Attach one terminal to the plus (+) terminal of the battery and the other to the Minus (-) side of the battery The speakers will push outward ( forward ) Mark the speaker terminals plus (+) and Minus (-) This way both speakers will in phase!
Excellent video! Can't say I agree with your conclusions on phase, though, especially when playing speakers in ordinary untreated rooms where half of what reaches your ears are (out of phase) reflections of the original signal. It's been my experience that gross phase issues will always have an impact on the measured frequency response, so if your frequency response looks good, phase is within reason.
Thanks for watching! I agree, rooms can make sound behave poorly. It was difficult to keep this video to just the basics! It's too easy to get into the weeds with audio...😅
Oh, I'm not looking to make it more complex than it is. I just don't agree with the conclusion that phase coherence as measured anechoically makes the difference you said it does. I know you've hung your hat of the phase / Faze connection and of course perfect phase coherence isn't a bad thing, but it goes out the window immediately in any real listening environment. BTW, thanks for the reply.@@infazeaudio
@@IBuildIt Like you say, phase coherence is a good thing, especially in portable speakers, since we can find ideal listening conditions! I didn't cover how these frequencies and wavelengths interact with a room, again, this is a very complicated topic and I tried to keep it to just the basics. Phase and magnitude response will be drastically different depending on where speaker is and where the listener is. My point is, starting with a speaker that is capable of producing in-phase sound from the start will be much better in almost any setting. I used to put sound systems in sporting facilities, hockey rinks, arenas, gymnasiums... Some of the worst acoustic spaces you can imagine, so I hear ya when you say it doesn't matter what you start with, it all goes out the window in certain spaces. Congrats on your channel, looks great!
Incredibly clear and concise explanation. Just discovered your channel and will be binging all of your videos.
