JBL PRX412M 12-inch two-way passive loudspeaker / stage monitor
The PRX412M is a passive twelve-inch two-way cabinet cut for double duty: stand it on a pole as a main, or lay it on its wedge angle as a floor monitor. Coverage is 90 by 50 degrees nominal, sensitivity is 95 dB at 1 W / 1 m, and it is rated 300 W continuous into 8 ohms. It needs an external amplifier.
The enclosure is DuraFlex-coated plywood behind a 16-gauge screen-backed steel grille, with a dual-angle pole socket and twelve M10 suspension points for light installation work. SonicGuard protects the compression driver from excess power without muting the box mid-show. Connection is on parallel Neutrik Speakon NL-2 / quarter-inch combo jacks.
