Commentary
The Control Series speaker system uses the newly developed woofer.
A 20 cm cone type woofer using newly developed white cone is mounted in the low range.
A newly developed white cone is used for the diaphragm. This diaphragm is manufactured using an oven method to increase internal loss and increase the sound spread in the mid-range while reducing distortion. In addition, the diaphragm strength is increased by laminating an embryonic polymer film on the surface of a pulp base made by fusing Super BKP and BKP.
In addition, by using natural pure rubber on the edge part, linear high stroke is realized. In addition, urethane copolymer is used on the center cap part to absorb unwanted resonance from the voice coil.
A 2.5 cm balanced drive tweeter is installed in the high range.
JBL's original pure titanium diaphragm is used for the diaphragm, and by making the shape of the edge part diamond type rigid structure, resonance in the high frequency range is divided, and clear sound quality is obtained up to the ultra-high frequency range.
Uses an anti-magnetic design.
The enclosure uses a bass reflex system.
The material is molded with polypropylene containing a special foaming agent to prevent resonance that causes sound quality degradation.
Various layouts are possible by using an optional item sold separately.
