Yes, the base/transformer assembly is attached to the panel with, iirc, 6 screws. Best to let the speakers sit with the mains (110v) unplugged overnight, the caps hold potentially lethal charges. Once the panel is detached there are 3 color coded wire groups that must be detached, they are held on with nuts & spade connectors so very simple. As you remove each connection, lightly touch it to each of the others, this will dissipate any residual charge in the panel, if there is any it will just make one little pop... just like touching a doorknob after walking across a rug.
The panels are light, and easy to handle, but unfortunately there’s no easy way to break them down any shorter, so transport & shipping are tricky.
