Short answer: the Ci3160RLM-THX is the no-compromise in-wall LCR; the CI200RR-THX is for a much smaller THX in-ceiling location. The first is a four-driver three-way with independently verified measurements, while the latter is an 8-inch two-way whose published curve needs more caution.
The Ci3160RLM-THX offers substantially more controlled full-range performance. It measures 58.6Hz at -3dB, has a virtually flat on-axis slope, and uses an aimable Uni-Q module plus dual woofers. Its large rectangular cutout and mounting depth demand a planned wall installation.
The CI200RR-THX is the practical ceiling alternative. Its 238mm circular cutout, 3.6kg weight, and 90dB sensitivity suit rooms that cannot take the Ci3160’s large cabinet. Its 82.5Hz -3dB extension means a subwoofer should be part of the system plan, and its vendor measurement does not provide a preference score.
Buy the Ci3160RLM-THX for a measured, aimable in-wall front stage.
Buy the CI200RR-THX for THX-certified in-ceiling duty where cutout size and installation simplicity matter more than bass reach.

The Two Speakers In Full
KEF Ci3160RLM-THX: $1,899.95 Amazon eBay
Pros: Independently measured by Audio Science Review on a Klippel rig to a genuine 58.6Hz at -3dB and roughly 36Hz at -10dB, with an on-axis slope of just -0.02dB per octave, essentially flat. Directivity is the most consistent of any in-wall or in-ceiling speaker in this category, with the tightest spread in its sound-power directivity index across the measured band. The rotatable, tiltable driver module (the RLM in its name) lets the tweeter and midrange aim toward the listening area even when the cabinet itself has to be installed off to one side. THX Ultra2 certified, with a 4-driver, 3-way layout: dual 6.5” woofers flanking a 6.5” Uni-Q coaxial midrange/tweeter.
Cons: At $2,299.99 each, a stereo pair runs roughly $4,600, among the most expensive options in this category. Listening-window and sound-power smoothness are moderate rather than class-leading, meaning some unevenness remains once you move off the main listening axis despite the flat on-axis trace. The 660 x 209mm cutout and 106mm mounting depth are large enough that they won’t fit inside a standard 2x4 wall stud bay without modification.

KEF CI200RR-THX: $898.75 Amazon eBay
Pros: An 8” woofer paired with a 1.5” Uni-Q tweeter (crossing over at 2.2kHz) measures a genuine 82.5Hz at -3dB and roughly 30.5Hz at -10dB, respectable low-end reach for a mid-priced in-ceiling speaker. The 238mm cutout accepts a large enough driver to move real air in a family room or media room. At $1,199.99 each, it costs about half of KEF’s flagship Ci3160RLM-THX while carrying the same THX certification.
Cons: Spinorama’s measurement of this model is a lower-confidence manufacturer curve rather than an independently verified Klippel scan, so treat the extension figures as directionally useful rather than as precise as the ASR-measured entries in this category. No Harman-style preference score has been published for it.
