Commentary

A compact monitor speaker developed for use in limited spaces such as broadcasting stations, editing rooms, and coordination rooms.

Equipped with 20 cm cone type woofer 116A in the low range.
The cone paper is made of a hard material with optimum mass and compliance. It has a loose low-frequency characteristics and a low distortion factor. It also uses a precision-processed aluminum die-cast frame to prevent unwanted resonance.
The voice coil uses a 5 cm diameter copper ribbon wire edgewise winding. By increasing the diameter, transient characteristics are improved and distortion is minimized. In addition, the magnetic circuit uses a large magnetic circuit using JBL's unique Alnico V magnet. The top plate, pole piece, gap, etc. are made with ultra-precision processing.

The 3.6 cm cone type direct radiator LE25-2 is mounted in the high range.
The cone paper has sufficient rigidity and appropriate internal loss, and is integrated with the center dome to enable clear high-frequency reproduction. In addition, in order to improve the directional characteristics of this unit, the diameters of the cone and center dome are made as small as possible to realize horizontal and vertical 90 ° diffusion capability.
The voice coil uses a 1.8 cm diameter copper ribbon edgewise wound voice coil. The voice coil is larger than the diaphragm to improve efficiency and transient characteristics. The magnetic circuit uses a high magnetic flux density of 0.7 kg and 15,000 Gauss.
The LE25-2 has a structure in which the periphery of the diaphragm is wrapped in high-density foam, which absorbs harmful spurious radiation and reflection, and enables clearer high-frequency reproduction.

The network section is designed with consideration of phase characteristics and impedance correction in order to smooth the connection between units.
In addition, low-loss inductors and capacitors with excellent characteristics are used in the parts to prevent frequency disturbance near crossover.

Equipped with a continuously variable level control, the level of the high-frequency range can be adjusted.

The enclosure is made with JBL's unique wood-well welding process to increase vibration resistance, and is made of 19 mm thick high-density compressed material carefully selected from the Particle Board, making it more durable and less susceptible to unwanted vibration.
The exterior is combined with a lustrous walnut finish and a blue front grill.
