Perfect. I have clamps, slide clamps, and glue. I opted for wood glue type II for immediate gratification and veneer and type III for everything else, especially if visible.
I also used fabric glue to adhere grill cloth to the frames.
So I take it rubber cement, super glue, model glue, epoxy, silicone glue, glass glue, and shoe goo are not wise choices for fixing speaker cabinets and frames.
