Since you need 2 cabs to get the full 200 watts out of it, I’m curious why it only has one speaker jack. If I want to run 2 cabs do I need a splitter or?
Most 8ohm cabinets come with a daisy chain parallel jack. Elf is far from alone in having a single speaker output.
I'm sure the Elf head only has (1) output to help keep it's diminutive size. Like others have said, just daisy chain from each cab.
