Short answer: the L-Acoustics SOKA. It ranks #10 of 33 column and line array PA speakers by sound quality, rated 3.5/5, at $5,400. The Coda Audio CoRay4 ranks #26, rated 3.0/5, at $2,380, $3,020 cheaper, which does not close the gap in sound quality.
The L-Acoustics SOKA is the more accurate pick. An ultra-shallow passive column only about 10cm deep, with very wide coverage and high output that hides against a wall. Its measured preference score, a predictor of how neutral it sounds, is 3.21 against 1.96 for the Coda Audio CoRay4. The catch: Bass reaches only about 128Hz (-3dB), so it needs a subwoofer or a bass companion, and it is passive, so it requires L-Acoustics amplified controllers.
The Coda Audio CoRay4 is the deeper-bass choice. A touring and installation column with planar wave drivers and very high peak output, and columns link into longer arrays for big venues. Its bass reaches about 82.5Hz before falling 3dB, against 128Hz for the L-Acoustics SOKA. The tradeoff: High-quality manufacturer measurements give a low 1.96 standalone preference score and 5.04 with an ideal subwoofer, with a 0.619 listening-window deviation, so tonal balance is uneven.
Buy the L-Acoustics SOKA. It is rated higher for sound quality, and the $3,020 saving on the Coda Audio CoRay4 is not enough to make up the difference.
