The single, 7-Series 708P 8" Bi-Amplified Master Reference Monitor from JBL is a self-powered reference monitor for critical music recording, film post, and broadcast-production applications. The speaker features JBL's popular Image Control Waveguide but with a smaller footprint and can be used to deliver natural output, detail, an expansive soundstage, and accuracy in a broad range of rooms.
 
The 2409H high-frequency compression driver incorporates a low-mass, annular diaphragm to deliver smooth response beyond 36 kHz with very low distortion. The 728G low-frequency transducer provides 14mm peak-to-peak excursion with greater linearity, delivering low-frequency output below 35 Hz. The drivers of the 708P are offered to deliver two to three times the output of existing studio monitors.
 
Furthermore, JBL's Image Control Waveguide ensures accuracy and neutrality while providing a wide sweet spot with increased sonic detail. The speakers dual-amplification system features a 250W amp for the 2409H high-frequency transducer and a 250W amp is dedicated to the 725G low-frequency transducer. This combination provides better output and allows greater listening distances, which is suitable for post-production or mastering environments.
 
Finally, the speaker also features onboard room equalization to compensate for adverse effects of room acoustics. In addition to twelve bands of Room EQ, eight bands of User EQ allow for customized response curves when placed behind a perforated cinema screen. User-enabled digital delay allows virtual alignment of speakers relative to the listening position, while additional AV Synchronization delay is available to compensate for latency in video displays.
