My left hi-fi speaker is really quiet, is it possible to fix it?
I've traced the fault to the speaker itself, namely the large speaker (it is accompanied by a smaller one in the speaker casing). The only thing I can think of is that the wire has worn out inside the speaker, could there be any other cause?
Answers:
There are two main failure modes in speakers, both involving broken wires.
First one of the "cat-whisker" wires that connect the speaker terminals to the central speaker coils breaks through fatigue failure. They are subject to a lot of mechanical flexing because they move with the speaker cone. It would be an extremely difficult repair because these wires are very tiny and glued to the speaker cone. If you did manage to fix it, it probably would not stay fixed - again because of the high mechanical stresses.
Second, the speaker coil may have been subjected to too much audio power and fried the entire coil. The speaker is a boat anchor at that point.
You can verify if the problem is a broken wire if you know how to use an ohmmeter. You should have 8 ohms across the speaker terminals if the wires are NOT broken. Make sure to disconnect external wires from that speaker (if there is any) when you measure. If you do not have an ohmmeter, take it to a Radio Shack and they will measure it for you.
If you find the speaker measures 8 ohms, then the wires are fine. The problem would then be corrosion or dirt jamming the speaker coil movement. This type of failure might be fixable - just clean around the coil with an electronic cleaning spray (with the speaker playing). This is a rare failure mode for speakers however. I only mention it because you said the speaker is quiet. If the speaker has a broken wire, it would be completely silent, not quiet.
first thing check the balance on your hi-fi. also make sure that no wires are touching.. also disconnect your speakers and swop them around.. this will determin weather it is your speaker that has the problem or your hi-fi.. im no expert but hope this helps.
If wires are connected properly and not loose at back you might have to take it to a repair shop
....Have you tried changing the speaker connections at the back of the Hi-Fi? This would eliminate any problems with your Hi-Fi. Next step is to remove the back from the speaker and check that all wires are properly connected, give them a wiggle with the output switched to the left channel. If that doesn't work, I fear you have blown your speaker. Although speakers are pretty reliable unless you play the music too loud. Good luck
if the wire is off inside the speaker on the actual woofer from metal input.. you can try to lightly solder the wire back on.. if it looks old.. even replace the wire with some new. you may get a bit better of sound quality out of it as well with new wires depending on your speakers age and brand. are you coming out of a sound card on your pc? or home theatre? if pc.. make sure and check multiple media players to make sure one side isnt turned down.. good luck.
If the speaker was at fault the smaller one or the larger one would still be loud.
However some speakers have a circuit card that splits the sound signal to the small and large speakers and that part could be damaged.
So tear into the casing (you have nothing to loose) and check it out.
if it don`t work hit it with a hammer, if that don`t work,- get a bigger hammer.
Does the speaker have a fuse? If yes, try replacing the fuse before opening the speaker and fussing with its insides.
