Commentary
Horn type tweeter unit of 5 cm diameter.
By using a large magnet and yoke with low magnetic loss for the magnetic circuit, and Permendur for the magnetic pole, the air gap magnetic flux density is 14,700 gauss.
The diaphragm is made of a plastic film that is light and highly rigid, and the mass of the voice coil is also small, making it possible to make the mass of the vibration system extremely small, enabling high-sound reproduction with little distortion.
The EAS-5HH45NA is an 8 Ω model and the EAS-5HH45NB is a 16 Ω model.
