Champ & Weber question

[Johnny Glow]

Yes, another Champ owner here who wants to put a weber 8a125 speaker in.

Simple, maybe stupid question. From my search on this board about this speaker, everyone says get the 4ohms. My champ has printed on the back 3.2 ohms. It looks like Weber offers a 3.2 ohms. What is the difference between 3.2 ohms and 4? Why does everybody put a 4ohm speaker when a 3.2 is offered.

Any insight is appreciated.


BTW, there was a SF vibrochamp listed in excellent condition this morning on craigslist here in the Bay Area for $100. Called immediately and it was already sold. Somebody got a steal!

What is the difference between 3.2 ohms and 4?

0.8 ohms! I am sooooo sorry.... I couldn't help it....

I got a 3.2 ohm 8a125 for mine... Dunno why people put in 4 ohms...

I doubt you'll hear any difference in tone or output.

The difference is negligible.

I've read that it's so small that Ted simply labels some of the Champ speakers 3.2 ohm for people who insist on having them.

You guys that have 'em labeled 3.2, check 'em with a multimeter and let us know what the reading is.

Most speaker companies don't offer 3.2, only 4. People just recommend 4 ohm as opposed to 8 because they don't know Ted offers 3.2.

Yikes... whoever told you that, punch them in the nose for me... just kidding.. We would never deliberately do something like that.

We actually DO make both 3.2 and 4 ohm coils. The confusion is that a 4 ohm speaker measures 3.2 ohms DC resistance, so many think they are one in the same and are certain I am delirious.

But, no, there really were 3.2 ohm speakers because they changed a front plate on the magnet circuit, and then shortened the voice coil by the amount they changed the front plate.. and that happened to work out to be 80% of what it was.
By coincidence, 80% of 4 ohms is 3.2 ohms.
See the confusion?
Our 3.2 ohm speaker measures 2.6 ohms DC.

Sorry for spreading misinformation, Ted.

I'm making knuckle sandwiches right now so they'll be ready for the punchin' picnic.
