Creamback into blackstar IDX:100
Celestion Cream - 90W 8ohm
I am looking to put a cream back into the idx 100. I am having issues finding rating and impedance for the blackstar. Do you know if this is an option and can I use a 75 or do I have to go to 90 or more?

The stock speaker of that amp appears to be Blackstar Anthem 100. A 100W speaker @ 4 ohms (written on the speaker in the pictures we can find of the amp). For that reason, we'd recommend seeking out a 4-ohm replacement that is at least 100W. Being a digital amp, the stock speaker is likely voiced quite flat and not like a typical guitar speaker, so choosing a replacement will be risky due to completely changing the tonal/EQ profile of what comes out of the amp.
