Pros: A 100mm deep on-wall speaker from JBL Professional with a single 3” full range driver, a 15 degree down tilt and a rain cover for outdoor use, wired for 8 ohms or 70V and 100V systems. JBL’s data shows a reasonably even on-axis response (0.65 average deviation) and a preference score of 4.68 with an ideal subwoofer.

Cons: Bass rolls off at 103Hz (-3dB) and about 80Hz (-10dB), and without a subwoofer its preference score is only 1.31. Sensitivity is a low 84dB and peak output 106dB, so it suits background music rather than loud playback. The measurements come from JBL and are low resolution, and the JBL SLP14 measures better.
