Features
E4550 is the device for reproducing exact sound.

E4550 has a quite strong alnico magnet that sizes are 125mm (outer diameter) x 80mm (inner diameter) x 65mm (hight). E4550 made to applying powerful magnetic braking to reproduce exact sound.

To raise magnetic flux density, using ring type permendule magnet and gap intervals close between pole and plate.

A joint part of the horn is cutting stainless stick, then milling by precision machining.

E4550 have no distortion feeling of the 1kHz - 4kHz most sensitive zone to ears, and It have transparent tone. This range is very important for the sound, because sensitivity of ears are the highest.
