No, I use one in a 1x12. But I can tell you right now that if you want a real Jerry sound, don't settle for the Commonwealth. Go for the JBL. I settled for a Commonwealth after settling for an emi RWB. Now I'm accepting that I'm probably going to be looking for an e120 in the not-too-distant future.
That being said, it's a very aurally pleasant speaker. It has a much warmer, mid-rangier quality than Jerry's speakers. Really clean, sparkly, smooth. Just a different resonant peak, as Brad put it to me. And the speaker, I now know, is a far more important component in overall tone than I ever before gave it credit for.
