I just installed a Weber ceramic Cali 10 in my Super Champ XD. It sounds amazing, but very different than the stock speaker. Very rich, gutsy and mean. The stock speaker is very well matched to the SCXD and installing the Weber Cali takes away some of the tonal variations. For example, the bass and treble controls have only a small effect on the Cali sound. But the richness of the clean tones and the power of the distorted tones are both exceptional. It looks great with the 4" aluminum dome behind the grill. I added 14" tilt-back legs, so now I consider it to be my mini Twin. I'll work on a youtube video this week.
I had to remove the tube protector cage for the Weber to fit, but it was really easy to install. Nice strong bolts and bolt fittings.
I wanted to install a purple jewel for the on light, but the SCXD does not have a screw-type cover, it's a one-piece.
