Acoustic near-field monitors - precise studio instruments, on which the correctness of the perception of sound depends. These speakers by definition have a minimal distortion in the reproducible. Monitors belong to the class of critical equipment of any sound studio or other production, connected with the production of a multimedia product. Perhaps that's why studio monitors are often bought by fans of "audiophile clean", accurate, dispassionate sound for listening at home - probably this option also has the right to exist.
Acoustic monitors JBL LSR705P, 708P belong to the "seventh series" of monitors JBL, which debuted at the exhibition NAMM 2017. Both models are created using the technology of the next generation of drivers, both are equipped with the patented waveguide of the high-frequency range Image Control Waveguide (which is used on the flagship control monitor M2 ), which allows you to get an accurate display of the sound picture with good detail in a wide "spot" listening - that is, when placing the listener is not strictly on the acoustic axis of the monitors. Both monitors are made in compact cases, which is important for modern studios. In addition, the front location of the bass reflexes allows the monitors to be placed as close to the wall as possible.

Active monitors JBL 7 Series demonstrate a deep, wide and large-scale sound stage, competing with much larger samples. Thanks to the built-in DSP for advanced equalizer and delay settings, as well as selecting an analog or digital input, the JBL 7 series is a high-quality option for near and middle field monitoring. Monitors are available in versions with a 5 "and 8" low-pass driver (driver size specified in inches in the last digit of the model name).
A five- or eight-inch driver is installed, respectively, in the model JBL LSR705P or 708P clearly determines their differences. This, above all, the size of the body and the sensitivity of the system. Accordingly, the lower limit of the amplitude-frequency characteristic and the maximum sound pressure level are shifted.
Almost everything else, including the high-frequency drivers installed in them, the LSR705P or 708P models are identical. This identity is also evident in the nature of the sound, which is a sign of a high class of development.
JBL 7 Series active monitors use the next-generation JBL technology to provide a larger dynamic range and provide an accurate frequency response.
The high-frequency 2409H contains an innovative ring diaphragm with a low mass, provides precise feedback to frequencies exceeding 36 kHz, with very little distortion. This is due primarily to the fact that due to the geometry of the membrane it was possible to achieve a piston version of its motion in the entire frequency range.
The 725G low-frequency dynamic head provides a 14 mm travel of the diffuser with a large linearity, allowing two to three times more pressure to be created than in other studio monitors that exist on the market.
Both monitors have an optimized built-in dual-gain system equipped with an EQ system that, in addition to 8 Room EQ bands, provides 12 bands of the user equalizer, allowing you to adjust the frequency response, and also to compensate for frequency losses, for example, when placed on a perforated cinema screen. The digital delay allows virtual equalization of the loudspeakers relative to the listening position, while the additional AV sync delay applies to delay compensation in the video path.
Control and switching are outputted on an identical panel for both models on the rear panel.
Due to the high quality of implementation and excellent parameters, both versions of the active JBL LSR705P and 708P monitors will find a wide application in both professional and audiophile monitoring and listening complexes, providing the highest quality, properly configured and corresponding initial sound.
