How to check if a speaker is working?
Likewise, people ask, how do you check if a speaker is working? Speaker Testing Option 1: Connect a 9 Volt battery to the leads of the speaker, positive lead to positive battery end and negative lead to negative battery end. If a pulse is generated in the speaker then the speaker is still functioning properly.
Do speakers have to have the same polarity?
It doesn't really matter which polarity the speakers are connected with, as long as they are all connected with the same polarity. Yes, if polarity isn' t the same for both speakers in a stereo setup, at points equidistant between the speakers you'll get cancellation when you should get reinforcement.
Can you reverse speaker wires?
Accidental reversal of speaker wires can happen when the wires are not properly labeled for polarity. Although this is not dangerous to a speaker or amplifier, proper power delivery and speaker response is not possible with reversed speaker wires. Reversing speaker wire polarity is a common audio error. Likewise, what happens if speaker wires touch?

What is the importance of connecting speaker wires to the speaker terminals?
The important thing when connecting speaker wires to the speaker terminals is to have all speakers polarized the same. This means matching the speaker wires to the same polarization of the source.
What happens if the polarity of a speaker is reversed?
If the polarity on one or a few speakers should be reversed from the system's polarity, it would create a phase difference where the sound from the speakers connected one way would cancel out the sound from speakers connected the other way, an effect more noticeable at lower frequencies.
Why is my speaker labeled?
Every speaker is labeled at the connection point to delineate which terminal is positive and which is negative. If you can still access the back of the speaker easily at this point in your installation, a quick glance at the terminals should tell you exactly what you need to know. Also, if you can look at either the owner’s manual or the top ...

Why do speakers have red dots?
In a stereo audiophile setup, speaker phasing is extremely important to achieve proper stereo effect.
What happens when a speaker cone moves?
When the connection causes the speaker cone to move to the front, the positive wire is connected to the positive terminal of the speaker. Obliviously the negative pole is connected to the other terminal. The cone will only move a little bit, do not hold the battery to the speaker for more than a few seconds.
How to tell if a battery is positive or negative?
As you know, batteries are marked positive and negative. Hook up the battery to the speaker wires and look at the speaker`s cone. If the speaker cone moves outwards the wire connected to the plus (+) terminal of the battery will be your positive.
How are speaker terminals labeled?
Speaker terminals are usually labeled by color or symbol. Speaker wires also usually have some identifier. One wire of the pair may have a symbol or tracer on its insulation or one insulation may be a different shape or one wire a different color.
What does the + sign on the speaker terminal mean?
One will be typically marked with a “+” or maybe some dots on one side so you can connect the positive speaker output terminal on your amp to the positive speaker terminal on your speaker. If you decided to turn it around and use the “+” marked side on the negative terminals, nothing bad would happen.
What color should the positive connect to?
If your amp or speaker has color-coded connections, the positive should connect to the red connection. If you are looking at the raw frame speaker inside the box, the positive should connect to the speaker terminal with the little paint mark or the + symbol next to it.
nonsqtr The emperor has no clothes!
Yep. "Usually" black is ground. But you'll have to look at where the wires go on the speaker to be sure, and even how the speaker is labeled. Usually one of the speaker terminals will have a little "+" sign next to it, which is the "hot".
billfitzmaurice Commercial User
Black and white are used all the time in household wiring, and in that case the black is always connected to hot, white to ground. While there is technically no positive or negative with A/C, if that standard is applied then you can expect the black to be positive (hot) , the white negative (ground to amp chassis). Test it to be sure.
nonsqtr The emperor has no clothes!
Yes, but that would be opposite to how most speakers are usually wired. You're absolutely correct that the black wire in a 3-prong AC cord is often the "hot". But usually black in speakers is "cold" (or ground). Might vary though. You're right, it's best to check, with a meter or something.
