JBL S143mk2

Commentary

A speaker system that refined all units of the S143.

A 35.5 cm cone type woofer is installed in the low range.
White cone made of natural pulp material is used for the diaphragm, and high rigidity aluminum die-cast frame is used for the frame.

The mid-range is equipped with a horn type mid-range combining a 5.0 cm driver unit 186 nd and a horn.
The driver unit 186 nd uses pure titanium diaphragm and neodymium magnetic circuit, and the back cavity is enlarged to improve the mid-range response.
MDF horn is used for the horn part.

A horn type Super Tweeter that combines a horn with a 1.9 cm driver unit is installed in the super high range.
Pure titanium diaphragm and neodymium magnet are used for the driver unit, and aluminum alloy casting horn is used for the horn.

The enclosure uses a bass reflex system.
MDF is used for the plate material, and round side panels with large round curvature are adopted for the side surface to achieve slimness while producing the volume unique to S143.
Marble top panel made of natural marble produced in Greece. High-mass marble on top panel suppresses unnecessary vibration of enclosure and reduces coloring.
Walnut style natural wood with high gloss finish is used for the exterior finish. In addition, by using satin brown color for the sa RUNNET, it creates an atmosphere that matches naturally with any room.

There was a round design speaker stand with the same finish as the S143mkII as an option sold separately.
