The center speaker system of the New A series aimed at pure and rich new generation JBL sound.

Two newly designed 13.3 cm cone type woofers tuned for the center speaker are installed in the low range.
The diaphragm uses pure pulp cone that optimizes the balance between the stiffness and mass of the diaphragm for New A Series.

A newly developed 3.8 cm ring type tweeter is installed in the high range.
The diaphragm of this unit uses a ring-type diaphragm with tangential ribs. The tangential ribs on the diaphragm transmit the driving force from the voice coil evenly to the entire diaphragm to obtain accurate piston motion of the diaphragm. This reduces the high-frequency distortion component and realizes clean high-frequency reproduction with less distortion.
The diaphragm is made of a special polymer material and has a dual layer structure laminated with damping film to suppress the high-frequency resonance of the diaphragm itself and realize flatter and smoother high-frequency characteristics.
The voice coil uses an ultra-lightweight copper-coated aluminum voice coil that is approximately 50% lighter than conventional copper voice coils, and the bobbin uses Kapton bobbin with excellent heat resistance.
In addition, the unit front is equipped with an aluminum die-cast outer horn which is firmly fixed to the front baffle. By firmly attaching this horn to the front baffle, unnecessary vibration of the tweeter is eliminated and sufficient regenerative energy is secured up to the crossover region.

The enclosure uses a bass reflex system.
It is designed by cutting the line from the rear side of the cabinet top to the front and then to the side of the front baffle. In addition, it is finished with a cherry natural wood veneer finish.
