Rather than carrying its own amplifier, the JBL 7-Series 705i draws on the 7-Series' centralised amplification and processing, so a stereo or surround array needs no power source at every cabinet — a modular, scalable 5-inch master reference monitor built for post-production and broadcast. Its 5-inch woofer reproduces frequencies down to 39 Hz and its high-frequency driver responds up to 36 kHz, while JBL's Image Control Waveguide delivers a smooth crossover and uncoloured response through the critical dialogue range, a neutral off-axis response for room-to-room consistency, and coherent imaging across screen channels, surrounds and overhead speakers. It combines with other 7-Series monitors and JBL's Master Reference Monitor into systems that scale to the room, is mountable and Harman HiQnet compatible, and suits fixed installs from a single edit suite to a full broadcast facility.
