AR(Acoustic Research) AR-3a
162,000 yen(one set, the 1966 release)
The speaker system which improved the squawker and tweeter of AR-3 announced in 1959.

A 2cm dome shape unit is adopted as a 3.5cm dome shape and a high region in the inside region.
By using the material developed newly, it is crossing low by making an aperture small, and this has improved the reproducing characteristics and directional characteristics of inside compass and a high region.
A 30cm high compliance corn type Woofer is adopted as 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.

System 3 ways, 3 speaker acoustic suspension system, and a book shelf type
Use unit or low-pass: 30cm corn type
For inside regions: 3.5cm dome shape
For high regions: 2cm dome shape
Frequency response 30Hz - 20kHz
Impedance 4ohm
Allowable input Suitable for 25W - 100 Class W amplifier
Crossover frequency 575Hz, 5kHz
Dimensions Width 355x height 635x depth of 292mm
Weight 26.5kg

AR(Acoustic Research) AR-4x
38,000 yen(one set, the 1967 release)
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.
Finishing of the exterior serves as oil finish of the walnut.

System 2 ways, 2 speaker acoustic suspension system, and a book shelf type
Use unit For low-pass: 20cm corn type
For high regions: 6cm dome shape
Frequency response 45Hz - 20kHz
Impedance 8ohms
Allowable input Suitable for the amplifier beyond 15W
Crossover frequency 1kHz
Dimensions Width 255x height 482x depth of 225mm
Weight 7.5kg
