An immense 2x15. The same size as the Ampeg 810e. Just as heavy too.
It sounds great with just about any head. The sound is not as tight as the 810e but, a lot more mid growl and slightly larger bottom end.
The 215e uses 2 cast frame 15's that have a wide range flat response up into the low tweeter range and is quite efficient.
