Very nice quality video thx audio university
Thank you. I learned something.
Glad to hear that, Italjute! Thanks!
Note that classic JBL and Tannoy drivers were built so that if wired CORRECTLY and faced with a positive voltage the cone would retract rather than push outward.
Hi, I'm using 3'rd speaker in standard stereo speakers with common ground/negative pin
I added 3'rd speaker between both positive wires of 2 speakers and it's provides surround sound for stereo songs, problem is some songs have badly editing creates noises in that 3rd speaker
Would you like to try making video on this?
Also if your amplifier has bridge configuration (no common ground for speaker or floating) then you can connect 4 speakers 2 as surround sound speakers
I have spent a hour trying to find out how to find the pos and neg post on speakers. My new speakers came with no papers. Thank you.
sailr8, did you buy those speakers from a guy with a white van on a street corner?
The inputs on the speakers aren't color coded red and black? Almost all speakers and amps are, with red being positive and black being negative
It doesn't matter which post is which as long as you match amp to speaker on both left and right channels, you will be fine.
Me to. Here is what I posted: Here is a question I have: I have two older vintage ADS speakers and the back terminals have neither positive or negative (red nor black) indicators. How do I know which to connect my speaker wires too?
@@natanpierce495 the larger connector pin is positive and the small one is negative.
Many years ago an audio technician gave me what was a revolutionary clue - adding a third speaker to a stereo pair - wired from the positive output terminal of each, and placed behind the listener, in direct opposition to the stereo pair - created a third channel which reproduced everything in the source material that was recorded out of phase (and would otherwise be unheard), resulting in a VERY three-dimensional audio experience. I loved it and it usually blew friends and guests away. Worked best in a room longer than wide. Did my set-ups that way for years...
Klipsch Heresy was originally developed as a center channel speaker to use between a pair of Klipsch Cornwalls.
And they say you can’t teach an old dog new tricks. You just taught me one. Subscribed.
Simple, straight-forward and precise! ... your videos are always useful Kyle. Thank you.
Hello Kyle. Your posts are very professional and helpful. I also appreciate that you have calm, understated intro instead of a crash/bang/boom one. Many thanks from a subscriber.
Thanks, Dennis! I’m glad you’re enjoying the videos.
@@AudioUniversityI have two 6.5 speakers in the back of my car, how do I wire them to my amp if I want both of them on one channel? I only use them for mids and highs, no bass. I have another amp for my bass
I did this some years go. I had a six-speaker setup: two in front, two in back and two speakers on top of each other in a corner facing the wall. For the corner speaker sets, I inverted the top speaker and the bottom one was wired normally. It really enhanced the overall audio experience, especially in low range frequencies. If you ever try this, the perfect song that bring this out is "Revolution Earth" by The B-52's. Part of the song is played out of phase and the corner speakers, with one wired out-of-phase, really makes that part of the song burst out. It is quite remarkable.
audiophile comes in different flavor - not just about how high quality sound is. i used to mess with speaker set up too. i would face certain speaker against the wall and others direct to me. the sound that scatter or bounce from the wall sound remarkable and different almost like its own full phased sounds stage on its own. this was during that time where 5.1 channel was new to consumer. people think i was into something that doesnt make the sounds sound any better. just like i like downward firing sub woofer. now you see a lot of audiophile who would mess with speaker setup the way we do. just like dolby atmos, those speaker have a upward firing to the ceiling.
i even used search for song that had only instrument and vocal separately. play one side of the room vocal and other side instrument. it sounded really good.
As a fellow audiophile I have known this for at least 40 years since reading about it in a magazine called Stereo Review back in the day.
well put slim. concise yet informative without missing detail.
Glad you enjoyed it!
Thank you so much for sharing your knowledge. Because of your video I was able to figure out the positive vs negative on my subwoofer. I've been asking and asking these guys for help and I just got tired of waiting. Now I can figure this out without anybody's help. Thanks again I sure do appreciate it ;-) take care
Hi Cindy, it is very simple. Red is positive and black is negative.
Mostly speaker cables are these colours
Or if the plastic is not colour coded then there is other method. In my car one wire is copper and the other is aluminium, tha plastic is transparent. In my car copper wire is the positive and aluminum is the negative.
I knew what to do and check for but I never knew why. Now I do and am grateful for another one of your excellent presentations👍👍
Thank you very much, really good lesson, loved the battery trick explanation.
This is called proper education. Thanks bro
Thanks!
While working as a DJ in the 70s the engineer installed a new turntable and somehow switched the polarity of one of the audio lines. The result was easily heard with the early stereo mixes, examples of which would be early Beatles recordings. The vocals were cancelled out, they could still be heard but weren't up to a true stereo sound. The issue went through the board to the transmitter to the listeners radio! As soon as it was mentioned to the engineer he knew exactly what had happened and fixed it.
Nice job. I immediately checked my speaker connections!
Cool videos & coherent explanation. This reminds me of the time I pulled the carry handle off my Fender Sound Enhancement speaker (16") and, to my amazement, discovered that all the sound was coming out of the back ass end of the speaker itself. Blew my mind! Cheers!
It’s great to see young guys interest in electronics and physics. It’s a fantastically well presented video
I had a problem on stage where we had two floor monitors for the lead vocalist. She called me up and said something sounds strange. We ended up removing one of the floor monitors from the stage to continue the show. When I investigated the two monitors at home, I found one of them to have reversed polarity soldered that way from the factory ! I fixed the connection and on the next show the problem was solved.
Lovely anybody can grasp it as smooth as it gets.
that's why my car speaker sound ugly, then when i fix it, Thanks to this video, my speaker sound perfect. the sound is clear and the bass, damn it feels good
I’m glad to read this, Jerome!
Love it.. professional explaination by simple method. Thank you Sir
I only could get it from this video from a couple of videos I have watched. I'm totally subscribed. Thanks.
Thanks! I’m glad you found what you were looking for!
Very complete video about my old question, and i loved it, cause it was more informative than i was thinking, so, that will be a big like and a subscribe to your channel! Good job!
Clear and concise - thanks for that..
Note that your position in the room with respect to the two speakers will determine which polarity is "correct," and that will be only for a small range of frequencies. For higher frequencies even changing the position of your head can noticeably affect how the sound is perceived.
Where it gets really interesting: A sound path, that adds up to a mono signal, where the stereo won't give an average, but extinguish each other, especially if the stereo effect is not too distinct.
When broadcasting FM/UKW, this is always done, and while music might sound somewhat weird, the mono voice of a speaker will pretty much become unhearable on mono receivers, if the phase of one channel has been connected incorrect along the signal path.
I’m into restoring vintage radios and test gear on my channel but I don’t know that much about the audio world. I am hoping to build a valve amplifier this year and learn a bit more about amplifiers and performance. Your videos are a great introduction thanks.
I thoroughly enjoyed this presentation. Ultra professional. My Heat Light and Sound physics professor could learn from the clarity here !
Sou brasileiro e achei agora seu canal! Esta de parabens!
Kyle you're a good man! Thank you for the explanations in your videos. Quite good!
Thanks, Anthony! Glad you like them!
Great, on the point, informative! Love it! Thanks!
Thanks, Patrik! I'm glad you enjoyed the video!
great video, extremely clear instructions, thanks!!
Thanks for watching, Max! I'm glad it was helpful!
Fabulous info given by you sir...many thanks...your channel is a textbook of audio engineering...HIGHLY APPRECIATED..
Ambient pioneer Brian Eno used to recommend using a third speaker in your system in addition to the normal left/right set-up, wired with both cables to the left and right postiive terminals of your amplifier. This produces an out-of-phase effect which may enhance your ambient listening pleasure and which, in my experience, doesn't seem to harm your amplifier.
Great yet simplified explanation of the topic, great video, thanks for sharing it!!
Glad you enjoyed it!
Excellent description of the science in speaker performance
I've used out-of-phase wiring in a small area, like an equipment cab, to bring out the stero separation. If one speaker has a weaker output, I use the in-phase wiring on that one to strengthen punch.
U learn something new every day , never paid atention on my speaker wiring , quess i have to go and check my wiring.
Don't bother, this is snake oil. The +/- markings are for convenience in keeping the two sides of a stereo speaker configuration in phase. That's the only thing that matters.
Exactly what I needed!
I'm glad the video was helpful to you, Alex Moore! Thanks for watching!
This was really helpful. Thanks!
Great info! Was always a concern for me! Thanks!
Thanks Kyle! Very informative and well-explained! Keep it up!
Glad it was helpful! Thanks for watching!
Well that is the best video I have ever seen describing sound waves from a speaker and polarity...good job
Me too but I've only seen this one.
@@x-man5056 lol
Thank you sooooooo very much brother , I was just going through the very same problem , thank you .
Great video. You have cleared my doubts. Thanks a lot. Keep doing pls
Thanks! I’ll keep making videos for you! I’m glad to help!
Finally i found the solutions, what i am searching for.
Thank you sir
Happy to help! Thanks for watching!
Great video! I'll be using this with my students. Greetings from Mexico City
Glad to help, Juan! If you have any requests for future videos, let me know! Thanks for watching.
Superb video; thank you.
Thank you for concise, informative video.
Glad it was helpful! Thanks for watching, Neil!
Thanks man! nice delivery keep it up
Proper polarity also helps create proper soundstaging and imaging among a properly set up stereo PAIR of speakers while you're listening to them in their sweet spot.
However, unless you're really listening for it, or if you're not at all an "audiophile", and instead you only "listen" to music as "background fill" and you don't really pay attention to it, then you're probably NOT going to ever even notice OR care about any phase or polarity inversions among your speakers OR in the music played through them.
Years ago I saw at a trade show a speaker cab with 2 drivers facing each other 1 with normal polarity and the other with reverse polarity
I always wanted to know what this is about. Thank you
I did notice a difference when you switched the polarities by listening to the drums. If the punch starts with a push, the drums sound a little bit more punchy than when it pulls. It will give you the illusion of the sound exploding outwards rather than imploding inwards.
Very well explained, no more bs statement good job👏
Excellent presentation!
Well done usual !
Make very well. Easy to understand.
Thanks for that information. New subs here from Philippines.
I have a vintage Fisher X202B Amplifier that has a phase switch to compensate for this without changing the wiring. It can also play only the right channel out of both speakers or only the left out of both. it also has stereo reverse as well as a control to blend mono to full stereo. Wish newer equipment had all these features
Great video, I knew something wasn't quite right in my car!
I hope this helped fix the problem!
Many years ago i was working in car stereo installation shop.In the car environment the difference of speaker opposite polarity is very well audible because the bass of the sound is hugely degrated.One speaker moves its cone forward while the other moves backward,one pushes the air and the other pulls the same amound of air and the total amound of air pressure in near zero.To fix this is enough to reverse polarity of one speaker to bring speakers in phase,it has no matter how are they connected in the output polarity as long as they have the same polarity wiring.
Fantastic review..!
Glad you liked it! Thanks for watching, Bill Wegemann!
Super clear concepts! Thanx!
Thanks for watching, Flavio!
Wow...all I can say is wow and thanks for this video...new subscriber here from philippines...
thanks for the clear video man
Thank you for watching, @Yeet! I’m glad it was helpful!
Always bothered me :D and in single speaker setup it doesn't matter. However now I know, that in multiple setup it does matter a lot :D and it makes perfect sense. Thanks for the simple and straightforward video!
great video amigo, thank you
Thanks for watching!
I recently provided PA system for a medium size outdoor event (~150 ppl) having 3 bands playing. I have Yamaha speakers - one pair 15" with horns mounted on poles on top of pair 18" sub woofers. I ran full range sound to the 15" /horn cabinets - used a Rane electronic crossover to send just lower frequencies to power amp driving the subs. I inadvertently hooked the subs speakers reversed polarity (power amp has banana plug type speaker connections making it easy to hook up speakers reversed).
The system had a very "full" sound to it...I received many compliments from both the bands and audience. Not until I was done did I noticed the subs were wired reversed polarity. I was surprised in that I thought if speakers were incorrectly wired a risk of blowing out could result (I drove the system pretty hard/ loud.)
Because it sounded so good I wonder if I could do it like this from now on?
It had such a good overall sound.
😁
* *Ray Bin,* * That's a cool discovery.
I have a JVC micro-component system in my mancave where the speakers are 4 ohms. If i wired two more of the same 4 ohm speakers to the original speakers, will I be over-powering the amp? Its a 20 amp.
I'm confused by many wiring tutorials on RUclips and sometimes they conflict eachother. This is a simple speaker add-on to fill my room so it sounds fuller. - Thanks in advance.
You touched on polarity reversal on one speaker. There is something else not mentioned and that is absolute polarity in a sound system. Some recordings are sensitive to that, particularly stereo recordings made with a stereo pair of microphones in Blumlein, ORTF, OSS, Coincident pair, and others. I have heard Sheffield Lab Direct to Disc piano recordings that sounded better and more realistic if the speaker set was wired(Both) in reverse polarity. the difference is subtle, but it exists.
Interesting - this is a highly debated topic, but I’ve heard convincing accounts on each side. Thanks for sharing, Yoda8945!
Confirmation bias most likely.
@@markrigg6623 Not really. In the studio, we found out that some voices sounded better while recording by switch polarity on the input channel of the board. It is due to the asymmetry of the audio.
Other instruments such as kick drums make quite a bit of difference as to absolute polarity. The difference between the initial impulse of the woofer moving toward or away from is definitely audible.
Thank you. Really helpful why my speaker does not play vocals of songs .
This is by far the best video about speakers polarity I could find. Excellent job!
Brilliant video

"For this example, it's best to use headphones" (Points to ears). Glad you cleared that up!
Great video!!!! Thanks a lot !!!
Dude, lets now see a video on quadraphonic setups from the 70s and using one of the 4 speakers phased reversed. Keep up the good work.
Awesome explanation
Echo, 😂. Love your video just amused on this one you have not sorted the room ethos. Keep up the great work.
One more very good video... 👏👏👏
wow awosome article learning..i hope u update how to learn about amp set up
03:47 wow, even with my low-quality computer speakers I'd noticed a really big difference. The bass is completely gone when only one speaker was "wired wrong"
The quickest sanity check is point both speakers at each other. If bass suddenly disappears you will know they are wired oppositely.
@@MyRackley I have some magic wood knobs I'd like to sell you for an outrageous price. It will make your stereo mind blowing. The silliness that passes for knowledge in the audio world is crazy.
@@MyRackley I have done this in the past and it works great for significantly reducing volume while allowing the cones to move. Your neighbours will love you for it.
Out of phase, each speaker is working to cancel each other out. The result is the impression of lower bass volume.
Informative thanks
Very good explanation.
Thanks!
Kyle, sir right head on. 👍
Well explained 👍👏
I used to reverse the polarity on vintage Fender amps, I was told by a good amp tech that they came out of phase and reversing put the amp where it should be.
I would like you to touch on this same subject but with regards of multi-driver speakers and the problems that a certain driver is wired incorectly. Thanks!
Good idea! It would have a very similar effect to the ceiling speaker scenario I mention in the video. Although, it would be more detrimental due to the proximity of the speakers in a single cabinet. Thanks for the suggestion!
Most people don't know this. Lamp cord has ridges in the insulation on one of the conductors. That helps you remember which wire is the hot and neutral. Yes, I use lamp cord as speaker wire. If it can carry mains voltage (120v 60hz here in the USA) to a light bulb, it can carry audio signals to a speaker. After all, audio signals are electricity.
When used as a power cord, the side with the ridges on the insulation is hot and the side without the ridges is neutral.
Low-voltage lighting wire is even better, it's just oversized lamp cord with 14 or 12-AWG stranded conductors. Removing the pretentiousness associated with "speaker cable" leads to big savings.
@@kc4cvh All the "audiophiles" buying overpriced speaker wire are being robbed. I refuse to pay $100 for something I can get at the hardware store for 25 cents a foot. As the old saying goes, " a fool and his money are soon parted."
Audio signals aren't electricity. They're tiny consecutive EMPs that get inhibited by non-uniform wire components on a molecular level. This is why OFC is so important, and also why you can *hear* the difference, but can't measure it when using silver cables with a perfect crystalline structure. It's lesser known, but the cables should also be free floating so the EMP isn't obstructed by walls or the floor.
Lamp cord! Your that guy that irritates pros. Jokes aside, most speaker cable is colour coded, so one should never be using power cords.
Very informative
Very useful! Excellent job!
Glad it was helpful!
great..... its so important
Thanks man 💯
Thank you.😃
Thanks to you now i know what happen to my car audio. The installer wired the rear left channel to a different polarity.
I agree the positive negative polarities does matter a lot in speaker connection.
Thanks a lot, ♥ Great video !!
