Short answer: the JBL Synthesis SCL-4. It ranks #16 of 28 in-wall speakers by sound quality, rated 3.6/5, at $7,259.90. The MartinLogan Tribute 5XW ranks #23, rated 3.2/5, at $6,999.98, $259.92 cheaper, which does not close the gap in sound quality.
The JBL Synthesis SCL-4 is the more accurate choice. A compact in-wall speaker with a horn tweeter, very even coverage and bi-amp terminals for custom theater installs. Its measured preference score, a predictor of how neutral it sounds, is 3.56 against 1.84 for the MartinLogan Tribute 5XW. The tradeoff: Bass is the weakest here, at 83.7Hz for -3dB and about 61.9Hz for -10dB in free air, so it needs a subwoofer.
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 83.7Hz for the JBL Synthesis SCL-4. The tradeoff: 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 JBL Synthesis SCL-4. It is rated higher for sound quality, and the $259.92 you would save on the MartinLogan Tribute 5XW does not close the gap.
