Yes, the spacing front and rear is symmetric.
The result of all asymmetric constructions of L shape aluminium strips mounted in rubbers, with the panels mounted on the strips, thickness of the panel side mounting rounds, give that the diaphragm is exactly in the middle between the dust covers. This goes for 63 model at least. Haven’t checked later models yet.
