The JBL PRX415M is a high-output 15-inch, 2-way passive loudspeaker designed for live sound, portable PA systems, stage monitoring, and installed audio applications. Its versatile enclosure can be used as a main PA speaker on a tripod or speaker pole, or positioned as a floor monitor for performers on stage.
The PRX415M combines a 15-inch woofer with a 1-inch 2414H-C compression driver and 90° × 50° coverage pattern. Rated at 300 watts continuous, 600 watts program, and 1200 watts peak at 8Ω, it is designed for use with an appropriately matched external power amplifier.
A dual-angle pole socket provides either standard vertical positioning or a 10° downward tilt, helping direct coverage toward the audience when the loudspeaker is mounted above listening height.
15-Inch Two-Way Passive Speaker System
The PRX415M uses a 15-inch (380 mm) low-frequency driver combined with JBL's 2414H-C 1-inch polymer-diaphragm compression driver.
The high-frequency driver is coupled to a 90° × 50° horn, providing controlled coverage for live sound and PA applications.
Frequency performance includes:
- 55 Hz–19 kHz frequency range (-10 dB)
- 66 Hz–16 kHz frequency response (±3 dB)
- 98 dB SPL sensitivity (1W/1m)
- 122 dB continuous maximum SPL
- 129 dB peak maximum SPL
300W Continuous Power Handling
The JBL PRX415M is rated for:
- 300W continuous
- 600W program
- 1200W peak
- 8Ω nominal impedance
Because the PRX415M is a passive loudspeaker, it requires a separate power amplifier.
That distinction is worth putting directly into the description. Someone searching for a PRX415M may otherwise assume it's powered because so many JBL PRX products are active speakers.
Main PA or Stage Monitor Operation
The PRX415M's enclosure provides flexibility for both front-of-house and stage-monitor applications.
For main PA operation, the speaker can be mounted on a standard tripod or positioned above a compatible subwoofer using the built-in dual-angle pole socket.
The socket provides two mounting positions:
- Standard vertical orientation
- 10° downward tilt
The downward-tilt position can help direct sound toward the audience when the speaker is elevated.
The enclosure can also be positioned for use as a stage monitor, making the PRX415M useful for portable systems where the same loudspeaker may serve different roles.

SonicGuard HF Driver Protection
JBL's SonicGuard protection helps protect the high-frequency driver from excessive power without interrupting loudspeaker operation.
This provides additional protection for the compression driver in demanding live sound applications.
Rugged Plywood Enclosure
The PRX415M enclosure is constructed from birch/poplar multi-laminate hardwood and finished with JBL's durable DuraFlex coating.
A heavy-duty 16-gauge steel grille protects the drivers, while an acoustically transparent internal screen provides additional protection behind the grille.
