May I ask which version of the Coincident Super Eclipses you're considering? I believe they may differ enough to warrant clarification in this discussion.
I have the original version in a 12 x 17' room being driven by about 100 tubed watts. I find the Supers somewhat picky about placement for two reasons: 1. their bass output is prodigious and can overwhelm a room with bass bloats and suckouts. 2. Their side-firing double woofers require a different approach to placement than front firers.
In the two different rooms I have used them in, I have found that placing the woofers on the inside and well into the room on the short wall works best. In my current setup, I place the mid-point between the two staggered woofers (on each speaker) at 63" from the wall behind them and 38" from sides walls (a la Cardas placement formula).
Another factor to keep in mind is the relatively high impedance of the Supers. This favors tube amplification since SS reduces its output significantly with higher impedances. The only SS amp I tried with my Supers was the 47 Labs Gaincard S (50-watt version) with double power supplies, and I did not find the result satisfying.
I can recommend the Supers if you have very smooth, tubed electronics and can be flexible with their placement.
As far as a direct comparison with either the Soliloquy 6.5 or even 6.3...never have done the side-by-side to know. I have heard other Soliloquy speakers and have liked them: integrated, coherent, musically meaningful presentation.
You can get these things from the Supers with low and powerful bass; you just have to work at it.
