Actually, my current room is 15 x 25 but I like trying speakers in different rooms, many of them small. I'm thinking that the 1C's would sound good in a small or large room were as the 2CE is better suited for a larger room. To this day the best sound I have heard at my house is a pair of MMG's in a 11 X 13 room with 14 foot ceilings positioned diagonally as Narrod suggested.
My first pair of audiophile speakers that I heard was a pair 2CE sigs at Audio Atlanta about ten years ago. They blew me away. Now it's time to buy Vandersteen for my own home after going through twenty different pair.
All things considered, other than bass, do the 1C's give me a good dose of the Vandersteen sound or are the 2CE sig II vastly superior sonically?
Thanks,
Pete
