Totem Model 1 Sig with Sub or Mani 2 without a Sub

I have a Pair of Totem Mani-2 with a Classe CA200 amp and they sound Clear with a great sound stage .I am wondering If a pair of Totem Model 1 Sig would have the same Clear and great sound stage as the Mani-2 do minus the good low end of the Mani -2 have? I am thinking of Switching to the Model 1 Sig with a sub to get a little more of the lower Freqs. any thoughs
