  • How can 1 tell what ohms a speaker is?

    I have an existing speakers that I am using for a HT. I want to replace the speakers in the existing cabinet. Problem is I am not sure what ohms the speakers are. Is there a device I can use to test or would it be wise to do this as long as I get the correct size drivers? Would I get an improvement out of the speakers if I did so?

    there are several ways...
    Google: measuring speaker impedance - and you'll get links, like

    It can be guesstimated with a simple DC resistance measure.

      An 8 ohm driver will read about 6 ohms resistance with a $4 Harbor Freight DMM. A 4n reads about 3.

      Replacing drivers based on purely their physical frame diameters is like, well, it's like a lot of really bad comparisons. I'm sure you can make up quite a few on your own.

      No way of knowing the answer to this. Unless they're seized up, it's not very likely. Now, if you took the box (provided its walls are thick enough), braced it, and found a pre-exitsting design that was made for that same internal volume, then you could try putting in THOSE drivers and the crossover designed for them, and THEN you'd probably end up with something better.
