What is the True Ohm reading of the SDA SRS series

What is the True Ohm reading of the SDA SRS series? SDA,2.3,3.1,...

Thanks

Here's the checklist that gives you readings for SDA's (3.1TL not included; I measured mine and might find the data....but need to look for it).

Impedence varies with load and a musical signal presents a variable load. Are you looking for the nominal impedence? What are you looking to accomplish?

Impedence measurements are usually taken using a constant test signal. My guess is depending on the musical signal and components used the ohms would vary between say 2 ohms to 500 ohms for a real musical signal.

I remember from an old Polk brochure - almost everything in the catalog had 6 ohm nominal impedence, from monitor 5 to SDA 1.2.

HT Rookie,

Did you write that article? If so kudos man. That was very informative.

nominal impedance, just getting ideas of what an amps watts per output is for a giving amp and giving SDA SRS.

I will admit I could not find the info on the 3.1's in the Compendium but I didn't want to ask just for myself.

That's a Polk document that has been around for a long time.

I'm out of the country until early August; when I get back I'l look for the 3.1 measures; I know I saw that piece of paper recently.
