Developed to meet the requirements of broadcast and post-production facilities that produce content in immersive audio formats, the LSR708i and 705i Master Reference Monitors are a modular system that can be scaled to any size production room and any number of channels.

JBL developed a new miniature high-frequency transducer—the 2409H—featuring JBL’s low-mass, annular diaphragm design that reportedly allows very high output with low distortion and high frequency response to 36 kHz for the 708i 8-inch two-way and 705i 5-inch two-way installed monitors. JBL also engineered two new high-excursion 5-inch and 8-inch woofers, the 725G and 728G, that are said to give the 708i and 705i low-frequency output into the 30Hz range and peak system output of 113 dB and 107 dB respectively.

JBL’s Image Control Waveguide and a dividing network work in concert to produce what the company describes as an imperceptible crossover transition, detailed, spatial imaging and neutral response. Front-ported birch plywood install-ready enclosures include bottom and rear-panel mounting points. With a range of available mounting brackets, the speakers’ placement can be optimized to maintain sight lines to video displays.

To reduce enclosure size and installation cost, the speakers are centrally powered by Harman’s Crown DCi 8|300N eight- and four-channel power amplifiers. The 705i and 708i can be driven by a single amp channel or bi-amplified, and tuned for room-to-room consistency Added to the 7 Series system, Harman’s BSS Soundweb London signal processor can be networked with the amplifiers to provide down-mix, sophisticated bass management capabilities and a range of I/O options including AES, Dante and AVB. The entire system can be externally controlled using Harman HiQnet Audio Architect software, a hardware controller or wireless tablet.
