Commentary
A 30 cm cone woofer developed for professionals.
2213H is mounted on 4311B.
The cone uses JBL original cone paper with Lancer Plus coating. The voice coil uses edge-wise rolled copper ribbon voice coil.
An SFG magnetic circuit is adopted for the magnetic circuit to realize a low distortion factor.
Rigidity is increased by adopting an aluminum die-cast frame with ribs.
