Commentary
This is a 25 cm woofer is also used in Exclusive model2251.
The diaphragm is made of natural pulp that has been aged, laminated with a special film on the surface, and coated with a unique damping paint. This diaphragm, combined with a 30 ° half-top angle ribbed shape, realizes natural sound reproduction.
The magnetic circuit is an internal magnetic type using an alnico magnet which can reduce the second harmonic distortion in principle.
By designing with allowance in the magnet operating point, the sensitivity decrease due to demagnetization at high power is kept low.
In order to stabilize the transmission of driving force, the yoke and plate of the magnetic circuit are integrally molded by a special casting method. In addition, the center pole is also screwed to the yoke, increasing the rigidity of the magnetic circuit by approximately four times.
