Re: infinity 3.5c , 2 powered Woofer 5.25" suddenly no...

The woofers on my 3.5c stopped working, but with mine the light was off. I unplugged it and left it for about 24 hours and then plugged it back in and it worked. No idea why. It's happened twice and each time takes at least 12 hours or a day or so before it'll work again, just unplugging it for an hour won't do it.

It seems like both times the problem started when the speaker got unplugged without it being shutoff first, but I can't confirm.

But if your light is still on it's probably a different problem. With my 4.1t towers when the light was on but there was still no sound it equated to numerous fried amp components which cost about $150 for repair.

Why does my woofer go off then back on again when I touch it?

A woofer consist of 4 parts, the diaphragm, the gasket ,the coil and the magnet. So when u touch the diaphragm it goes back on after no sound?....assuming this is what happens, there are 2 wires running from the coil to the diaphragm it could either be broken or worst case the coil itself has a broken or burnt coil wire. Recoil the coil if that is the case, idk from where u are but in RSA we get recoiled replacement kits for these situations

MX6050D Subwoofer Issues

Hello, welcome to Fixya!

Fault is either from the main system or the sub-woofer itself.

You need to test both unit in order to detect which of the two is giving the fault, so that you can concentrate on the faulty unit.

Test the woofer with a AA battery or any other battery. Put your ears close to the woofer and observe if you will hear any sound. If the woofer makes sound, then it means the woofer is working, but if it doesn't make sound, then it means the woofer is defective. Or you can disconnect one of the working speakers and connect the woofer to that part. If there is no sound, then obviously, the woofer is defective.

If the woofer seem to be working, then the unit needs to be tested also.

Connect one of the working speakers to the sub-woofer's section of the main unit. If the speaker doesn't bring out sound, check the system's menu settings, check the volume and make sure the sub-woofer volume is raised to the highest level and not on mute. ( Note that most Theater systems has separate volumes for each speakers). If the volume is raised to the highest level and there is still not sound from the woofer part, then it means the woofer channel has burnt. It could be a fuse or a defective channel. At this point, I think you need help from a repairman.

I hope the above is clear.

No sound out of 15 speaker and only about half the sound out of horn

1. Confirm the woofer is not blown. Remove it and test it by using an AA battery and wire from the battery to the woofer terminals. When connected, the cone should jump. Alternately, if you have a meter, you can measure impedance. Infinity (or no jump with the battery method) means the coil is open and the speaker needs to be reconed.

2. If the woofer tests good, inspect the connections and wires from the input. Ensure there are no breaks. If the crossover includes a PC board, check for cracks or solder breaks and blown fuses / thermal damage. Repair as necessary.

If the woofer tests good and the wiring and connections are sound, reinstall and test. If there is still no sound from the woofer, test it by conecting it directly to the amp. If there is audio coming through the woofer, the issue lies within the cabinet. Consider replacing all internal cabinet componentry, including inputs. If the input is a 1/4" jack, it is likely thae contacts are bent out, away from the connector. Bend them back to center slightly, and clean them with alcohol or "deoxit".

"Half" the sound from the horn seems normal, as it is not intended to produce bass. If you mean half-volume, that is dependent on settings and measurements and is difficult to diagnose. clmrt5000_1.jpg

The voice coil is open, you can look real close at the spider wires that are soldered from the two terminals to the cone to see if they are bad, otherwise you will need new woofer, you can try getting the woofer from
