Short answer: the Revel W553L. Both are rated 4.5/5 for sound quality (#2 and #1 of 28 in-wall speakers), and the Revel W553L costs $1,089.90 against $3,773.90 for the KEF Ci3160RLM-THX, so with nothing between them on sound quality, price settles it.
Why pick the Revel W553L: An in-wall speaker with excellent, accurate sound for the money, a swiveling tweeter, and mounting for left, right or center. The tradeoff: At $545 each a stereo pair costs twice that, and a separate amplifier is required.
What the KEF Ci3160RLM-THX does well: An excellent in-wall speaker, with highly accurate, flat sound, very consistent dispersion and an aimable driver module for off-center installs. Watch for: At $1887 each, a stereo pair costs twice that, among the most expensive options in this category.
Buy the Revel W553L. Both are rated the same for sound quality, and it costs $2,684 less than the KEF Ci3160RLM-THX.
