Could someone please explain Ohms to me

    If you read my other post, you'll see that I've used combos all my life, so I really didnt have to worry about ohm ratings. Now that I'm thinking about a head/speaker stack deal, I know that I have to understand what the difference between ohms ratings are. Could someone please give me the just of it.

    p.s. sorry if this is a stupid question.

    Definitely not a stupid question. There's been lots of threads on this, I'll start digging and see if I can find one for you. Try a search and see what you come up with. What I find I'll post here for you.

    Hey, I didn't write it. :)

    All I know is my amp sounds good to me! ;)

    I could have done just fine with: Ohms, a way of expressing resistance. As in, "That cabinet has a resistance rating of 4 ohms." ;)

    Much easier on the ol' grape.

    JMX's avatar should be a big, throbbing brain! ;)

    Here's an easy analogy to help get your brain around the concept:

    Think of the electrical current (power) that flows from your amplifier and through your speaker(s) as water, flowing through a pipe (the wires and voice coil). Imagine water flowing through a garden hose....when the hose is straight, the water flows easily. Bend the hose a bit, and the water flow is IMPEDED somewhat, bend it more and the flow is IMPEDED even more. Resistance to the flow, in other words. This same type of resistance upon electrical current is called IMPEDANCE and it's expressed in units called OHMS.

    Ohms are the units used to measure how much resistance a device like a speaker or resistor creates when current is passed through it.

    Or sumthin' like that....
     
  8. So what you're saying is it's pronounced as "im-pee-duns" :D ;)
