Our Sierra-2EX have exceptionally wide horizontal dispersion and considering your speaker placement and sitting off center, the wide dispersion of these speakers (no dome can match the wide horizontal dispersion of the ribbon used in the S2-EX) will be extremely beneficial.
Regarding amplifier power -- one quick but important question, how far back will you be sitting from the speakers?
Thanks in advance!
