Commentary
38 cm cone type woofer unit used for L300.
JBL's unique die-cast mass control ring mounted on the back of the center dome extends the playback band smoothly to the lower range while preventing deformation of the voice coil and cone paper.
It uses a 5.4 kg magnetic circuit using a 10.2 cm diameter edgewise wound voice coil and strong magnet.
