Since I have ran my surround sound speakers to a proper position I have been able to hear them finally, I originally had them set over the mains. Very rarely do I hear anything come out of them, have done the audyssey calibration, set the crossover setting to 120hz, checked the distances and that's all good. In my haste of purchasing them I realize now that the S-20's would of been a better option and better match (100watts vs 50watts) I am however pleased with the C-10 center with the F-30s, they seem to match up very well.
Would upgrading to the S-20s produce more / better sound out of the surrounds? Because of a better match to the mains?
If I got the S-20s could I use the S-10s else where? Front heights?
Because of my living room layout, (sliding glass door to the right and stairway to the left of the main listening positions) the surrounds are not directly to the sides; they're about a foot behind to the left and right of the main listening positions and 6 foot up, total distance to main listening position of 13 for both. Running rear surrounds wouldn't be possible because of a half wall separating the living room and kitchen.
