National EAS-20PX85

Commentary

2-way 20 cm compound type speaker unit.

Using a unique edge made of foamed synthetic resin, the minimum resonance frequency is lowered by making the compliance large enough for stability.

A horn type tweeter using the EAS-5HH17 driver is mounted in the high frequency range.

Heat resistance is improved by adopting a unique aluminum foil voice coil bobbin.

3 magnets of 30 φ x20cm are used for yoke with low magnetic loss.

Die-cast frame is adopted.
