Technology

Patent Pending Image Control Waveguide

First introduced in the JBL M2 Master Reference Monitor, the Image Control Wave Guide technology allows

A seamless crossover and uncoloured response in the critical dialog range.

Neutral off-axis response for greater accuracy and room-to-room consistency

Detailed imaging and a coherent transition between screen channels, surrounds and overhead speakers.

Next Generation Driver Technology

Meeting the dynamic range and extended frequency response requirements of today’s production formats, 7 Series incorporates JBL next generation “Super Drivers.”

The new 2409H High Frequency transducer incorporates an innovative low-mass annular diaphragm that delivers smooth response beyond 40 kHz, with extraordinary output and very low distortion.

JBL developed custom low frequency transducers for remarkable performance of the 7 Series

New 725G and 728G 5” and 8” high-excursion low frequency drivers in the 705i and 708i deliver continuously high output with minimal power compression and low frequency response into the 30Hz range.
