JBL LSR708i 8-Inch Master Reference Monitor: Next-Generation Sound for Post and Broadcast Production

The JBL 708i is a cutting-edge 8-inch master reference monitor designed to revolutionize multi-channel monitoring in post-production rooms, broadcast facilities, and production trucks. As part of JBL's innovative 7 Series line, the 708i leverages patented technologies developed for the flagship M2 Master Reference Monitor to deliver unparalleled audio performance in a compact enclosure[2].

Featuring JBL's renowned Image Control Waveguide, the 708i provides detailed imaging, extended frequency response, and remarkable output. This advanced waveguide technology ensures an acoustically seamless transition between the low- and high-frequency transducers, resulting in a wide soundstage and precise imaging. The monitor's smooth on- and off-axis frequency response allows for neutral reproduction across an expansive listening area, making it ideal for a variety of room configurations[4].

The 708i's custom-designed low-frequency transducer utilizes JBL's patented Differential Drive technology, which reduces power compression for sustained output and extended linear low-frequency performance. This innovative driver design, coupled with JBL's precision-engineered port, produces accurate bass response at all playback levels, ensuring exceptional audio quality for critical listening applications[4].
