Speakers stop working at higher volumes?

Question

I have some older tower speakers by jvc i believe, and they always worked fine. There are three speakers in each one, and some had small tears around the speakers in the rubbery part, but i dont think thats the problem, since they still work at lower volumes, and ive seen speakers with the same problem, but much worse, working better than mine.

Well, one day i noticed that when i turn the volume up on my receiver, especially when i turn the bass up a bit, then at about 50% volume or so, the speakers just click and produce no sound for a couple seconds. Then if i leave the volume at the same level, they turn back on for half a second then click back off for a couple again.

If i hit the back of the speaker box after this happens, they turn back on momentarily, untill the sound overwhels it or whatever, and they turn off.

If i lower the volume after they click off, they turn back on, but at a lower volume (until i hit the back of them)

Whats the problem?

I believe the speakers are slightly more powerful than the receiver. My dad had the receiver for a long time, its probably from the 70's or so, and i dont believe its really even that powerful, although it gets loud. He told me i wouldnt be able to blow out my speakers with that receiver, lol thats about all i can say about that. But in all those years he had them and they worked for me, they never did anything untill recently.

Answer 1

Sounds like your speakers are drawing to much from your receiver at high volumes, no doubt do to a low-impedance speaker system. Either you will need to keep the volumes lower, get some 8-Ohm nominal speakers, or get a receiver than can handle low impedance speaker systems.

.Hi These intermittent problems are sometimes hard to fix.Are you able to unscrew the back to see if there is a loose wire where the crossover circuitry is located .Also check the terminals at the back where the leads from the amplifier are connected and tighten them if needed. The tears in the rubber surround could be affecting it somehow. Have you tried them with the bass decreased to see if they stay on .The bass speaker might be at fault.Without actually seeing them it's a bit hard to give a suggestion.
Someone else on Answers might have a better solution.I hope you get them fixed
Cheers.

Answer 3

sounds like an overload protection of some kind ... does the ohms on the output of the receiver match what the speakers are ?

Answer 4

Most likely it is you amplifier clipping. It does not do any harm to either speakers or the amp. This is as load as your system will play.

If you want to play your speakers louder - get another system.
