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, 7.9 lbs (3.6 kg) 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.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
