Magnepan mc1

Why don't Magnepan mc1 speakers have a fuse like the rest of Magnepan's speakers?
Question...Does the MC1 have a separate tweeter section with thin wires? If it is run full range with the woofer-type wires it doesn't need a fuse. The fuse (in the MG1.6 at least) is just in the tweeter circuit.
Yes it's a 2way speaker with quasi ribbons
