As a former Dyn C1 owner I can only comment on those. I have heard some Totem speakers used Dynaudio drivers. But Dynaudio never sells their current production driver, and if those in the Totems are Dynaudio drivers which driver are they? From the Focus/Contour or Confidence series?
That said my room is very similar to yours and had them set up on the long wall. They worked very well and I even had a Rel B3 with the crossover set to 36hz to add the lows the C1's can't do. So they go pretty low on their own. If you should decide on the C1's make sure you get the Stand2/4/6. They make a difference.
That said there are 3 versions of the C1's. The originals sounded the best at the higher spl's. The MKII/Sig had a crossover redesign along with an upgrade to the internal wiring and a new coating on the Esotar2 tweeter. Since I owned both the original and the Sig's I will say the MKII/Sig sounded much better at lower listening levels, BUT they won't play as loud as the originals before bottoming out. The newest are the Platinum's which only offer a cosmetic difference over the MKII/Sig.
Best of luck whatever you decide
