monitor 5b ohm load

Sax

heh... so here's something interesting. I'm up on polksda.com and in one of the monitor manuals it shows the monitor 5b to have a 4ohm load, 10-125watts.

the other shows 6ohms, 10-125watts.

So... are my monitor 5b's 4ohm? or 6ohm? That is the question.

more accurately I suppose I should ask, what is the proper method for determining ohm load of a speaker, when it is an unknown?

You can hook up your multimeter, set it to ohm, and measure the resistance at the terminals (with no wire hooked up). It's not a sure fire method, but it will read generally lower than the nominal impendance.

Eg: An 8 ohm nominal speaker might read between 5.2~ to 7 ohm. A 6 ohm speaker, typically 3.8~ to 5.1 ohm. 4 ohm nominal, 2.5~ to 3.6 or so.

At the end of the day, unless you are just curious, with a proper amp it won't matter. If you are trying to determine which tap to use on a tube amp, lower is always better than higher - use the 4ohm tap.

hmm... true. It just seems curious to me that a "5b" would have been made with different ohm loads. Seems to me that a certain model in a line would have the same characteristics.
