|AR(Acoustic Research) AR-92
|118,000 yen(around the one-set and 1980 time)
3 way floor type speaker system of the vartical series which inherited the
design philosophy of AR-9 and adopted the almost same composition as AR-91.
The 25cm corn type Woofer is carried in low-pass.
The unit of a
1.9cm dome shape is carried in the 3.8cm dome shape and the high region in the
The same thing as AR-91 is adopted and these units put in the
magnetic fruid of the shape of colloid which is tinged with the magnetism of
NASA development between the voice coil and the yoke, and they have improved the
input-proof while they aim at distorted reduction from a central axis as a
structure as for which Bure is not.
Furthermore, the acoustic blanket which
is a special sound-absorbing material was attached to the surroundings of a
unit, and sound quality degradation by reflective sound is prevented.
A "17AWG sky core coil", a "computer class electrolytic
condenser", "input-proof [ unguided quantity ] ceramic resistance",
etc. are used for the element of a network part.
The acoustic suspension system of AR tradition is adopted
as the enclosure.
By this system, air can achieve the duty of a spring by
carrying out full sealing of the core, compliance can be enlarged, and it is
possible to make low-pass resonance frequency lower.
Moreover, walnut tone
vinyl chloride finishing is given to the exterior.
