    Hi all,

    Plus got a brand new set of Onkyo speakers and passive subwoofer for my Onkyo 507 amp.

    Problem I have an subwoofer that is passive and not sure how to connect it? It only has speaker wire connectors on the back of the sub and no phono points.


    Any pointers is gratefully received :)

    You need an amplifier connected to the sub output of the Onkyo to feed to your new speaker.

    Sorry, not sure what you mean?

    I have a 507 amp and trying to connect the subwoofer to it. The speakers are all connected, but the amp only has phono points for a subwoofer, yet my sub only has speaker connections?

    You can't connect a passive sub to it. You'll need to buy a new sub. I'm guessing that all your speakers are from an older all-in-one system? If so then you should buy a whole new set of speakers too. The all-in-one sets use more power than usual and they may damage your amp if you use them with it.
    I had the same issue. Bought some Jamo A102 speakers.

    The speakers were brand new still wrapped and strapped. I was led to believe this was fine for my amp :(

    Being new to this area, took the advice at face value!

    The speakers I know are suitable for my amp, I checked the ohm's of them first.

    So I need an active or powered sub then? Are powered amps all the same, ie do I need to buy a specific amp or most ok?

    TIA

    Which speakers are they? And if the ohms are ok then they should be fine.

    I would think you'd need a powered sub. I don't know of any amps that work with passive ones (though I don't doubt that they exist) I hope someone else will be able to advise an amp for you or know which sub to pair with your speakers.
