Another silly extension cab question-Can I use a 16 ohm cab with a 4 ohm Champ?

...and what's the sound difference between 4, 8, and 16 ohms anyway? Is it SPL differential?

no,no and no !!!

many fender ams will tolerate a 100% mismatch ...i.e an 8ohm load can go 4 or 16...Too risky to go 4 to 16 .If you go up you`ll lose power and punch ....some could actually prefer the softer vibe .
Don`t know what happens if you move down.
Depending on the circuit you could put too much strain on the tubes/tranny .In the case of the Champ ..nothing but 4 is acceptable (3.2 actually) .Surely there are more qualified people here to guide you , I just made the first post in an attempt to save your amp in case you were ready to wing it !

Thanks! No, I'm not going to plug in and see what happens. I just see all of the cabs seem to be 16 ohm. Guess I need to buy an empty cab and a 4 ohm Weber 10 or 12".

in a larger cab the champ will sound like twice the amp ....big fun!
are you by any chance getting 16ohms out of 2 8ohm speakers?
If so ...you could rewire them to give you 4 ohms

No, this would be for a single 10 or 12" cab. I have a DRRI for when I need the amp onstage with a band. This cab is to be isolated offstage to feed the PA and IEMs. The 8" Weber in it sounds good, but I'm afraid that I'm going to blow it to pieces eventually.
