CS390

CS390

The CS390 by RezCom and SoundLab may be the most compact speaker in the lineup, but don’t let its size fool you—this is a clarity-first loudspeaker purpose-built for precision, articulation, and flexibility. Originally designed as the blueprint for the larger CS890, the CS390 focuses its output on speech and recorded music, with an ultra-light 3" sub that offloads most of the audible frequency range into the electrostatic panel—resulting in a jaw-dropping level of vocal and midrange detail. Whether used in seminar rooms, teaching spaces, or tucked into hard-to-cover zones of larger venues, the CS390 delivers sound that’s focused, articulate, and astonishingly natural. At under 20 pounds, it mounts easily with a standard VESA bracket and is ideal for installations where space and simplicity matter. In practice, it’s become a go-to for hearing-impaired sections of churches, as well as schools, libraries, or conference rooms where clear speech and detailed playback are essential. Whether paired with a digital whiteboard, seminar mic, or classroom projector, the CS390 delivers immersive sound without ever becoming intrusive.
