Short answer: the Grimani Systems Rixos-L on measured sound quality, the MartinLogan Tribute 5XW on price. The Grimani Systems Rixos-L ranks #20 of 28 in-wall speakers, rated 3.4/5, at $16,400. The MartinLogan Tribute 5XW ranks #23, rated 3.2/5, at $6,999.98, $9,400.02 cheaper.
What the Grimani Systems Rixos-L does well: An active in-wall speaker with its own rack amplifier, very high output and wide, even coverage for a home theater. The catch: Audio Science Review measured a preference score of only 2.16, or 5.53 with a perfect subwoofer, because on-axis response is uneven (0.64 smoothness, 0.55dB average deviation).
The MartinLogan Tribute 5XW is the deeper-bass choice. A slim, efficient in-wall speaker with a folded motion tweeter that rotates for vertical or horizontal mounting. Its bass reaches about 74.7Hz before falling 3dB, against 87.9Hz for the Grimani Systems Rixos-L. The catch: The measurement is the weakest of the in-wall speakers here: a preference score of 1.84, or just 4.91 with a perfect subwoofer, with on-axis smoothness of 0.30, an average on-axis deviation of 1.56dB and wide directivity swings (SPDI deviation 3.25dB).
Buy the Grimani Systems Rixos-L when sound quality outweighs the price for you, and the MartinLogan Tribute 5XW when the price outweighs sound quality instead.
