Speaker troubles
My Boston (2.1) Speakers have been having some trouble. I have had the
speakers for about 5 years now and up till now they have been great. Lately though the volume level goes up and down sparatically without me touching anything. I think it is a short. What should I do and how do I fix it. Thanks!! |

That sounds like a speaker cable problem, actually. Look for a loose connection at either the speaker or the amplifier. |

This may be a dumb question, but have you swapped the speakers round to determine that it is definaely the speaker that is faulty? Gareth. |

Especially when he specifically says 'speakers' (note plural), it sounds like he should be looking at something common to both stereo sides...in this case the amplifier or receiver. Just a guess would be a faulty volume control pot, but often even that manifests on one channel at a time.... jak Gareth. |

Speaker troubles
Thanks guys for all your help. I looked for lose connections and there
didn't seem to be any. But when I opened up the speaker case and looked around I saw that were that where the negative wire is soldered onto the speaker it seemed to be burnt (there are black and brown marks around it). Do you think that this is the source of the problem? |

Do you think that this is the source of the problem? sometimes a maker will put markings on soldered connections that will easily indicate if the unit has been tampered with and thus violate warranty. look for loose connections, loose parts on the crossovers, cracked PC boards. |

Do you think that this is the source of the problem? Given that heat arises in a conductor which is too thin for the current needed, I would guess that the cionnection has fatigued and partially broken. That burn-marks are not normally a feature of speaker wiring makes me suspect that this may indeed have some bearing. While it was open did you do the obvious, and re-terminated the wire ? Did the intermittancy go away ? geoff |

Do you think that this is the source of the problem? The black and brown marks may just be flux (the stuff that is in the core of solder and is supposed to burn away when you solder but never completely does). But that is the obvious connection to check. I'd take it off and redo it. |
