do I now understand you don't already own the speakers?
that room, only 10 feet wide, is not easy for any sound setup, the speakers are probably going to be in and stay in the corners.
Cornwalls are not near corner speakers. And too big to move around such a narrow room, especially with a piano between them.
For that room, I would go for primaries with limited bass extension, getting bass reinforcement from the corner placement, and, after much listening, if then desired, add a self powered sub. I would avoid ports or passive radiators also.
I mentioned my large speakers. TOOOOO much bass when in the corners. I need to move them out of the corners for listening, toe them in, and tilt them back slightly, They are well over 100 lbs, the Cornwalls are 98 lbs. I built a base to tilt them slightly, and conceal 3 large casters (2 in front, 1 in rear, 3 always level themselves without shims). Large casters, if you have wood floors, to avoid marks in the floor, any weight distributed by 3 is heavier per leg/support/spike than 4: pounds per square inch, or pounds per caster contact surface, or pounds per spike.
