    I own an old pair of Castle Stirlings, they're brill, but today i lost some volume in the left speaker.
    It hasnt cut out....its just lower now than the right speaker.
    I have to adjust the balance on the amp otherwise i can hear most of the sound coming from the right.

    But putting an ear upto the units reveals sound, and the cones are moving ok, so i'm stumped

    The Stirlings speaker set up is like this .....

    Sounds like the crossover is degraded in some way, or maybe cables have deterioted.

    Swop the speakers over, this will determine it's not the amp.

    Was just gonna say swap left and right to see if its the amp or the speaker ... but as nathan has already said that I'll just say it again ...

    Try swapping left and right cables to make use it's the speaker not the amp. If it is the speaker ... contact Castle they will probably be able to help you.

    I'll try that Nathan , thanks.

    The cable is new ( a week ago ) so hopefully i can rule that out.


    EDIT :

    Just swopped speakers over at the amp , and the volume discrepancy has now shifted to the other speaker ??

    So is it the amp ?

    If you swapped the outputs of the amp, and the volume discrepancy has shifted ... sounds like it's the amp or the source that has the problem.

    Do you have the same problem with all input sources? If not, try plugging the source into another input on the amp. If you have the same problem with all inputs then it's probably a problem with the amp - what is it and how old is it?

    Hi Vikki, its the same with all sources.

    Its 3 days old, so have just contacted the supplier and they've agreed to pick it up for testing

    Cheers all

    I bet the caps in the crossovers are SHOT.
    Caps degrade in about 10 years.
    Those things look state of the ARC:laugh:

    Except for the fact that swapping the speakers over on the amp the volume problem occurs on the other speakers.

    Just because speakers are old doesn't mean they arn't any good wookie - a lot of people use speakers 10 - 20 years old and prefer them to any modern speaker.

    I have got KEF eggs in my bedroom.
    I run a KEF REF system in my serious room.

    I think you will find that capacitors do have a working life in a loudspeaker dividing network.
    As the caps de-grade, so does the output signal reaching the drivers voice coil's.

    Could be a dry joint in the amp.
    Those speakers do look capable!

    wookie ... yes Capacitors have a working life ... but if you read the thread then you'd have realised that the problem wasn't with the speaker but with the amp!!

    Also your post implied (weather intentional or not) that because they were old ... they must be rubish!

    They are. They can handle 135 watts and not peak either. They weigh a ton ! Castle acoustics is an all british company, and make very impressive speakers






    Eggs akly ! :D
