The Records and Recording Magazine writes “Excellent performance… a steady frequency response which many more expensive systems would find it difficult to equal… this unit, measured objectively, confirmed fully what I expected to find after listening to it with a wide range of programme material. The AR-4x is a loudspeaker of very high quality, made and designed to high technical standards. It is not very often that one finds such a completely successful enterprise as this.”

The speaker system which changed the model of a tweeter based on AR-4 which was put on the market in 1965 and called explosive popularity.
A 6cm corn type unit is adopted as a 20cm corn type Woofer and a high region low-pass.
The acoustic suspension system is adopted as the enclosure.
This system was a system by Mr. Edgar Villchur’s invention, and it was developed in order to remove the fault of the speaker till then with which harmonic distortion increases especially in low-pitched sound.
By this system, the box without corn paper with high intensity, an air leak, and resonance by which full sealing was carried out is used, the parasitism vibration at the time of a low-pitched sound play is braked, and distortion is suppressed.
