Z5300e center speaker no longer works

That's not how speakers work Ben. All speakers have magnets, but they are not a switch. The magnet makes the energized coil in the centre move and make noise in the floating cone.

The center of the speaker cone is attached to one end, which gets driven back and forth by the moving coil. This cone is held at its edges by an airtight suspension or surround. As the cone moves, it pushes and pulls the surrounding air; by doing so it creates pressure waves in the air, called sound.

How do speakers work? - SoundGuys

Hi, when a speaker does not work, you might need to do some troubleshooting tips to know exactly where the problem is .

First you will need to test the speaker cone if it's working properly by using an AA battery and two wires to make sure the cone is working..

Connect one of the wires to the Positive side of the speaker, and the other on the Negative side, And after that use the battery to hear if the speaker cone will make a click sound.

If it doesn't make a click, that means the speaker cone is Bad, you will need to replace the speaker cone,
But if there is click from the speaker cone, that means the speaker is Ok, and you might need to trouble shoot your stereo to be sure if the sound IC chip is Ok in the stereo..

Hope it helped..

Probably something was touching the speaker cone and you snapped the speaker back so it no longer touches.

Looks like a broken copper braid that links the speaker terminal to the cone (from there on it goes to the coil which is underneath the cone).

Check the speaker connection terminals (near the magnet), you will notice that each terminal has a copper braid wire going from that terminal to the speaker cone.

Inspect both braid wires carefully at each end (near the speaker terminal and near the speaker cone), there will either be some damage to the braid at one or more of these four locations or the braid could be actually broken at any of these spots.

The braid can actually be resoldered at the point where it's damaged or broken - this task will require good soldering skills, mainly because this kind of braid wires are difficuld to solder (they are a bit difficult to clean because of their structure and solder won't attach itself well to oxydized copper), but also because some speaker cones are made of plastic which may melt if you overheat it with a soldering iron.

Besides that, when resoldering is being done, only a very short portion of the braid should be wetted with solder because the solder point will become rigid when the solder cools down, and the braid needs to remain very flexible when the speaker operates (if it's too rigid or too short, damage to the speaker cone could occur or the braid could get broken again when the speaker will be playing at a loud volume).

Hope you can have it repaired, it can be done at home, but there are also speaker repair shops where you can get it done (i'm not sure about the prices though).

Anyway, the alternative is to replace the speaker itself.

Swap speakers over...check the balance isn't fully to the other channel...swap left/right phono cables over (if thats how your using it) other than that i would say is broke.
Easy way to check speaker cable/speaker... touch a small battery (like used in a remote) across speaker wires, you will hear and see the speaker cone move.

Hello adeisenroth,

Sounds like the voice coil(s).

First make sure that the braided wiring going from the sub cone to the voice coil(s) have not come loose. Examine the braided wire all the way from the terminal to the cone. If one or more has come loose, it can sometimes be resoldered. Just be careful with the heat.

If all the wiring is intact, you can check the coils with a multimeter. With the sub disconnected, and the meter set to the lowest resistance scale, test across the speaker terminals. Depending on how the coils are wired you should measeure somewhere between 1 and 4 ohms. If you get "0" or no reading at all, one of the coils is open. If you get "infinity", a coil is shorted. Sometimes only one coil is bad and you can still use the sub, wiring it to the remaining coil only. Once you have determined that one set of coils is either open or short, you can remove the jumper and test each coil individually.

You can test most any speaker voice coil with a small battery. The best to use is the 9V type that has terminals right together. Connect a short piece of speaker wire to the sub terminals, and hold the other end of the "+" wire to the positive battery terminal, then quickly touch and remove the negative battery terminal with the "-" wire. The sub cone should move outward, and you should hear a brief thump. If no cone movement, and no thump, the coil is defective. Do not hold DC to a speaker for any period of time though, just touch and remove. And NEVER use a high-current battery, like a car battery for such a test. If the coil is not already bad, high DC current will damage it.

Either short or open, replacing a voice coil is a job for the Rockford-Fosgate professionals.

Contact MMats Pro Audio at 561-842-0600. They can re-cone it for you, or sell you the re-cone kit. If that does not work for you, contact MWA Speaker Parts in Tuscon - 520-647-7193. They can sell you a re-cone kit, or they can direct you to a speaker repair center near you. A third option would be to contact Sundown Audio in Troutman, NC. They may be able to re-cone it for you.

can you swap speakers with other one?if so do this and if speaker still sounds bad it is definately the speaker. there is really no way to take speaker apart and repair

It's ok. Mines are red too. Different models have different colored lights.
