I just got a 5.1 surround sound home cinema system. The subwoofer has a great sound but there is a very annoying crackle coming from it at the same time. I have tried using a different subwoofer with the same impedance (3Ω) but the crackling persists...

 

Does this mean the amp/DVD player is broken?

Could it be the cable from the amp to the sub?

What is "breaking-in" and does it have any relevance?

Would help to know what the system is.

But guessing from the 3ohm, it is an all-in-one HTiB.

You can try a different cable since it's the cheapest test you can do but from the sounds of it (no pun intended) it could be a blown voice coil in the sub. This is usually the reason for crackling. Does the crackling happen at all volume levels or just when you crank it up?

 

If you had popping sounds, then that would most likely be bad capacitors in the amp.

 

Break-in has no relevence in a crackling sound from any speaker.


Time to play!

Hi, I would say something is wrong with either the wire or the amp that drives the sub.. Since you tested it out on a different sub and the problem persisted, like said above check the wire first..
