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 uncolored 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.

System Integration

  • Modular and scalable for number of channels and room size
  • 7 Series Studio Monitors and the JBL M2 Master Reference Monitor can be combined to produce a wide range of systems
  • Compact enclosures and mounting hardware allow versatile mounting options and unobstructed sight lines
  • Centralized amplification and processing eliminates the requirement for power source at each speaker location
  • BSS BLU link Networked Audio for ease interface and reduced system noise
  • Harman HiQnet equipped components can be centrally controlled via hardware, software or wireless tablet
