RE: Question about speaker impedance

Posted by vanmeterannie on June 18, 2020 at 07:01:57:
In my experience, it's more an issue when mixing drivers since (again, in my experience) a mismatch there can affect the relative volume and therefore the overall performance. You'd definitely get the best performance with a match but it's not as if it won't work, and with a driver as you're using at that size you'll be getting mostly midrange anyway.
You can probably roughly estimate the impedance using a multimeter, although I'm sure others here will chime in that it's not accurate that way as there's no current going through the driver, but-yet again, in my experience-the rating you get just measuring off the terminals is usually correct.
I have a small portable from the 50s with a 7" driver of unknown origin that I also rebuilt (replaced the turntable with a different machine that I could install a more modern MM cartridge in) and I use the original tube amp, and love it. But I get why you might want to change it out.
