30cm woofer unit for a wide range of small to large enclosures.

Features

◎Diaphragm

A pulp hybrid curved and straight cone with concentric ribs for increased rigidity is combined with an ether-based urethane foam uproll edge. The well-balanced diaphragm, which combines moderate rigidity and internal loss, reproduces solid bass to support the entire music.

◎Frame

To support the heavy magnetic circuit and accurately transmit the amplitude of the diaphragm to the air
A highly rigid aluminum die-cast frame is used.

◎Magnetic circuit

A large φ156mm ferrite magnet is used in the magnetic circuit with a T-type pole piece that smoothes the magnetic flux flow and reduces distortion during voice coil amplitude to ensure sufficient driving force.

◎Voice coil

Long voice coil with high input resistance (Xmax:4.75mm)

◎Input terminal

Large threaded terminal posts are used to accommodate banana plugs.

◎Rubber gasket

A rubber gasket covering the entire outer surface of the frame is installed.

This contributes to clear and habit-free sound quality by controlling sound radiation from areas other than the diaphragm.
