I lost my balance once and toppled one of the Reference Three's little siblings, the Reference Ones, off it's stand, a three-foot plus drop directly onto it's upper edge. The fall barely chipped the veneer. It the cabinets of the Threes are anything like those of the Ones, a little reworking and re-skinning of those cabinets might well do the job.
In any case, those have to be some wonderful-sounding speakers.
