Subwoofer speaker compatibility

    Hi all,

    I have an old Bush subwoofer without speakers (55W I think).
    I was going to get 5 new speakers (centre, front left, back right, rear left, rear right) from a used Panasonic home entertainment system.

    What do I need to check to make sure they're compatible?

    P.S. I do intent to get a decent set-up at some stage but until then...

    Thanks

    What's the model number of the Bush?
    The DVDAV11K used 4 OHM speakers. 8 OHMs will probably be fine but won't be as loud.

    BTW, that 55 watts is power consumption, not audio power.

    I'll have to check the model number. As long as it's not going to damage the amp/speakers I'm happy.

    D'oh!

    FYI , you have a old Bush "Subwoofer with integrated multichannel amp "

    Most subwoofers dont have multichannel amps. Just an amp for the sub channel.

    Also , watch out for those panasonic speakers , clearly they are from whats called an all in one box , where the amp was either integrated into the disc player or the sub.

    The speakers on such units are only ever meant to be hooked up to that unit and that unit alone , and in a lot of cases serious damage can be done by hooking them up to other units.

    Check the speaker impedances carefully , if they are 4 ohms or more then you will probably be OK. But a lot of those all in one boxes have speaker impedances less than 4 Ohms , such as 2.5 or 3 Ohms. If that is the case , then they are useless on anything else , they will overload the integrated amp and kill it.
