Axiom's focus has always been function over form. The cabinets are a little dated for sure. But IMO there are also uglier "better" speakers out there for sure.

Could you make or modify the grilles to meet your needs? You can use the existing as a template and cut the new grill backer out of 1/8" plexiglass or similar. Then wrap in speakercloth and spray adhere on the back. You can use sticky tac to adhere it to the cabinet (it is removable and leaves no residue.)
