AR(Acoustic Research) AR-92
¥ 118,000 (1 unit, around 1980)
Commentary
This vertical series 3-way floor type speaker system inherits the design philosophy of the AR-9 and adopts almost the same configuration as the AR-91.
A 25 cm cone type woofer is installed in the low range.
It is equipped with a 3.8 cm dome type unit for the middle range and a 1.9 cm dome type unit for the high range.
These units are the same as the AR-91. A magnetic colloidal magnetic flux developed by NASA is inserted between the voice coil and yoke to reduce distortion and improve input resistance.
In addition, an acoustic blanket, a special sound absorbing material, is installed around the unit to prevent deterioration of sound quality due to reflected sound.
17 AWG air-core coils, computer-grade electrolytic capacitors, and non-inductive high input resistance ceramic resistors are used for the elements of the network section.
The AR traditional acoustic suspension system is used for the enclosure.
In this system, the air acts as a spring by completely sealing the inside, and compliance can be increased, and low-frequency resonance frequency can be made lower.
The exterior is finished with walnut style PVC.
