Commentary
38 cm cone type woofer which adopted high efficiency magnet and relatively light cone paper.
We have achieved excellent low-frequency characteristics by adopting unique systems such as curved cone paper, cone suspension with special damper system, and voice coil gap of 0.36 mm or less.
It can be used for bass horn drivers and multi-woofer systems in theaters and halls.
It can also be used in the bass reflex method, but in that case the bass response will be a little lower.
The 2220 comes in three variations : 2220A with 8 Ω specifications, 2220B with 16 Ω specifications and 2220C with 32 Ω specifications.
