Genz Benz GB 18B with JBL E155-4?

Just so we're clear, I won't be trying to mod the acoustic 406 should I decide to pick it up in the future*

Upgrade to drivers with better power handling? Possibly. But won't be looking to modify the cabinet, as it's my understanding that it's not nearly as straightforward as adding ports to the rear of the old trace Elliott, sealing the ones up front.
