I could use help from someone who knows their audio stuff because I do not want to make a mistake. I am looking for a front left and right main speaker to match with my present system. I have all Mirage Omnipolar speakers: one Omni S-8 subwoofer (100 W continuous to 400W), two Omnisat Micro surrounds (100W each), and an Omni CC-1 Center Channel (150 W), powered by a Yamaha RX-V657 receiver (95W x7). My questions are:

(1) Will any of the Ascend loudspeakers match up with my Mirage speakers? I am especially interested in the CBM-170. Or would the timber be too different?
(2) Can the CBM-170 be used as a main front speaker in a small to medium size room?
(3) Any other recommendations for me? THANKS!
