Symmetry Series by Axiom - Symmetry implies either a quantitative equality of parts (the perfect symmetry of pairs of matched speakers) or a unified system of subordinate parts. Naming Convention: S2.0 for matched pair or S2.1 for system including sub OR Symmetry 2.0 or Symmetry 2.1, etc...

/EDIT

For some reason I did not get an edit function when I posted the above, so I had to resort to more straightforward means.
