How does a speaker polarity work?

How do you test speaker wire polarity?

Observe polarity and touch a 1.5 volt battery to the terminals and note the direction the speaker cone moves.

Can speaker reverse polarity damage speakers?

No. Reversing the polarity does not damage the speaker. The only issue in connecting it backwards in a stereo setup is the speaker cones will not be moving in sync with each other, so stereo imaging and bass response will suffer.

Does it matter if the neg and positive speaker terminals are switched Both ways seem to work?

Reversing the polarity of the speakers will cause them to run "out of phase" meaning that the speaker will be pulling. It might not be noticable to some people but it can really bother others.

How do you connect new 6x9 rear speakers to the factory wiring in a 1990 Mercury Topaz?

First of all you will need to snip the factory connector off near the speaker(s) you intend to replace. Then it is a matter of trial and error to get the correct polarity. If the polarity is reversed, you will still get sound out of the speaker, however, the tone coming out of the speaker will be higher (little to no bass). If that happens, reverse the wires and mount the speakers.

Which speaker wire is the negative the black or the striped?

There is no agreed convention for speaker color coding. Most users and most manufacturers will take the striped core as the "+" side and the black or plain as the "-" side. It makes no difference to the connections how the cable is connected but in a system, make sure that all the amplifier terminals are connected to all the speakers with the same polarity. Almost all amplifier and speaker connectors that have red and black terminals will use red as the "+". Therefore, connect the red terminal to the red terminal and the black to the black. It makes no difference which core of the cable is used. If different speaker manufacturers are being used in a single system, it is possible that the wiring may be inverted on one type compared to another. Wiring a speaker with the polarity inverted will never damage the speaker but it does affect the sound quality when used with other speakers. Most of the better speaker manufacturers will state the polarity of the connectors in their manuals. Look for a statement like "A positive voltage on the red terminal will produce a forward movement of the speaker cone". If you are able to confirm this detail for all speakers, getting the polarity right is simple. Although speaker connectors are often referred to as positive and negative, the signal is AC and therefore the terms are not strictly correct. The terms work for the purposes of connecting speakers so there is no need to correct the terminology.

How does a computer speaker work?

Just like any other speaker.

What are the effects of the electrode polarity on welding in the SAW process?

Think of Polarity as water flow in a pipe. Reverse Polarity means the flow is from the work to the machine. Straight Polarity is flow from the machine to the work. Heat is released when the flow tries to jump the gap. So in Reverse Polarity (where most SMAW is done) the heat builds up in the base metal which is usually thicker than the Electrode. The extra heat there helps melt the base metal. Straight polarity is usually employed when welding thin metals.

How do your feelings work?

what feeling about work does the speaker prove

Why won't a flashlight work if the batteries are in the wrong way?

It won't work because the polarity of the batteries is reversed.

How do you check the polarity on a car speaker?

With a simple flashlight battery.Connect wires to the speaker then breifly touch the wires to the battery and watch the speaker.If you have positive to positive and negative to negative the speaker will "push outwards" if you have it reversed it will "suck inwards"

Do onions make a speaker work?

no they do not

How do you reverse polarity natural magnet?

Demagnetize it, then remagnetize it the opposite direction. It's a lot of work and it would undoubtedly be easier just to repaint it and claim you reversed the polarity.
