JBL 708P - 250W 8-inch Powered 2-Way Master Reference Monitor with DSP and EQ in Black Finish

The JBL Professional 708P is a self-powered, 8-inch reference monitor designed for critical applications in music recording, film post-production, and broadcast environments. Leveraging JBL's groundbreaking Image Control Waveguide and next-generation driver technologies, the 708P delivers extraordinary output, stunning detail, and an expansive soundstage. This monitor provides several times the output of comparably-sized studio monitors, delivering unmatched dynamic range and allowing for greater working distances. The result is a reference monitor that is perfect for environments such as post-production studios, mastering, and other critical listening applications where every sonic detail matters.

At the core of the 708P are JBL's patented transducer technologies. The 728G low-frequency transducer incorporates JBL's Differential Drive technology, which helps to reduce power compression for greater sustained output, offering linear low-frequency performance below 35 Hz. Paired with the 2409H high-frequency compression driver, which uses a low-mass annular diaphragm, the 708P provides extraordinary high-frequency output, with smooth response extending beyond 36 kHz and low distortion. These transducers deliver exceptional low-frequency output and pristine high-frequency detail, ensuring an accurate representation of your mix across the entire frequency spectrum.

The JBL 708P also features the acclaimed Image Control Waveguide, originally developed for JBL's M2 Master Reference Monitors. This technology ensures an acoustically seamless transition between the woofer and high-frequency transducers, providing precise imaging and a wide sweet spot. This allows the 708P to deliver a neutral frequency response with a smooth, on- and off-axis frequency response, making it suitable for a broad range of rooms and environments. Whether you're mixing on-axis or off-axis, the 708P provides accurate sound reproduction, ensuring that every detail is captured regardless of the listening position.

With a built-in dual amplification system, the 708P uses a 250W Class-D amplifier for the high-frequency transducer and a 250W Class-D amplifier for the low-frequency transducer. This bi-amplified design offers unparalleled output and dynamic range, allowing for greater listening distances and ensuring that every detail of your mix is clearly audible even at peak SPL. The 708P's maximum continuous SPL of 108 dB and maximum peak SPL of 114 dB makes it capable of handling demanding production environments, delivering powerful, accurate sound even in large rooms.

The JBL 708P offers extensive room compensation capabilities, including 8 bands of Room EQ and 4 bands of User EQ, allowing you to adjust the speaker's response to the unique acoustics of your space. The 3-position HF trim switch lets you adjust the high-frequency response to suit your room acoustics or personal preferences, while the user-configurable Room Delay and AV Sync Delay ensure that you can fine-tune the speaker's output for perfect alignment with your listening position and any video or AV equipment. These advanced features make the 708P incredibly adaptable, ensuring accurate and reliable sound reproduction in any production environment.

Designed for the most demanding environments, the JBL 708P is housed in a robust ported enclosure made from 12mm birch plywood, reinforced for safe mounting. The speaker is protected by a durable steel grille and features mounting points for both top and bottom installation. The 708P's sleek design, advanced DSP features, and exceptional performance make it an indispensable tool for professionals in music production, film post-production, broadcast, and other critical audio applications.
