    Hi, my new 18 watt combo has a 12 inch 16 ohm speaker..the selector switch(located at rear of amp) for impedance of speaker is set at 16 ohm. I would like to get another cab with a 12 inch speaker..
    What should the speaker impedance be and what would I set my selector switch too? I don't understand how that works...

    Thx
    Rich

    Get another 16 ohm speaker and set the amp to 8

    will any other ohm speaker work or is that the only combo?

    Depends on the available impedance switch settings. Without make/model, we can't even look that up.

    That's going to be the only convenient option. Anything else will result in impedances like 5.3 ohms (8 and 16) or 3.2 ohms (4 and 16) which no amp has settings for. They're be safe at the 4 ohm setting, but not correct.
