How to check if speaker wire is working?
It is rare that a single speaker is not working at all. If the wires correlating to the speaker are fully connected, but the speaker is not making any sound, then you need to check the integrity of the speaker wire. If you have a multimeter, then test the impedance level. To test the impedance level, set the multimeter to measure ohms (Ω). Disconnect the speaker wire and touch the red probe to the red or positive speaker lead, and touch the black probe to the black or neutral speaker lead. The multimeter should read anywhere between 6-16ohms. Usually, a speaker will have an impedance level of around 8ohms. If you don’t have a multimeter, here is a cheap one that will work for many different things. It is a handy tool to keep around the house. Without a multimeter, a simple test for this is to use a spare speaker wire. If the specific speaker is in-wall or in-ceiling, then you will need to unmount it. Connect the spare speaker wire to the speaker and the binding post where the original cable was connected. If the speaker works with this connection, then you my friend, have a faulty cable. If the speaker is still not outputting any audio, then it is possible that something is wrong with the receiver’s port or the speaker itself is defective. You can easily test this by disconnecting the speaker wire from a known working port, then connecting the spare speaker wire to the known working port.
How to tell if speaker is out of phase?
For example, there are 5 speakers, 4 speakers move outward simultaneously and one speaker retracts inward. The speaker that retracts inward is "out of phase". Its movement is contradicting the movement of the other speakers. To check the phase of the speaker, you will need to look at where the leads or cables are connected on both the receiver/amp and speaker. Depending on the cables used, the red or marked wire will almost always connect to the positive (+) jack and the other cable to the negative (-) jack. In general is best to always wire your system in phase, red/marked wire to the positive jack and black/solid wire to the negative jack. Abnormal setups may actually require you to wire a speaker out of phase, but this is pretty uncommon for a home theater setup. If changing the phase doesn't fix this issue, then it is likely that your speaker has bit the dust.
What is the crossover point for a speaker?
The crossover point is usually set to 80Hz, which is a little higher than what most normal sized speakers can produce well, but this can be adjusted. I recommend only setting a speaker to "large" if it contains an internal sub, otherwise, I would make sure all speakers are set to small.
What does it mean when a speaker retracts inward?
The speaker that retracts inward is "out of phase". Its movement is contradicting the movement of the other speakers. To check the phase of the speaker, you will need to look at where the leads or cables are connected on both the receiver/amp and speaker.
How to calibrate a receiver?
Each receiver will run the calibration and configure the settings a little differently, so it is best to double check what has been set. If your receiver didn’t come with or doesn’t have the ability to use a calibration mic, then there are many different applications out there to help calibrate your system. These are called SPL meter applications, they can be downloaded to a smartphone and used in replacement of a calibration mic. Note that this will not be as accurate and as easy as a calibration mic. Calibration mics typically do a good job with setting the distance and level of the speakers, some additional adjusting may need to be done to the crossover and EQ.
What does "small" mean in a speaker?
Usually, you will have the option of either small or large. Selecting small or large is usually determined by the speaker's ability to pass a full range of frequencies. Most small speakers cannot pass or produce a lot of low-end frequencies thus it would be set to "small".
What is the impedance of a speaker?
Usually, a speaker will have an impedance level of around 8ohms. If you don't have a multimeter, here is a cheap one that will work for many different things. It is a handy tool to keep around the house. Without a multimeter, a simple test for this is to use a spare speaker wire.
