Not sure about the Tweaker cab, but I have both the Rebel 30 combo and the 112 ext cab.
I just replaced the Egnater elite 80 speakers with Celestion V30's that are about 10 year sold and there is simply no comparison.
Wow.. no comparison....
The Elite 80's had a low mid spike that can muddle your sound.
I didnt even realize until I put in the V30's. So much more efficient and clear at higher volumes.
I'm not sure what speaker is in the Tweaker cab, but I bet it's also the Elite 80.
Its not a bad speaker, pretty balanced, but for sure has a low mid spike.
