INFINITY Infinitesimal-IV
80,000 ( It is 1 set in two sets, around the 1990 time)

Description
@
The compact speaker system developed as the first phase of Infinitesimal Series.
Naming originates in compact speaker and Infiniti simal I, II, and III which appeared in 1979.

The 10.8cm corn type Woofer is carried in low-pass.
On the IMG (Injection Molded Graphite) corn of the graphite strengthening polypropylene which is acknowledged as technology original with Infiniti, the low-pitched sound play beyond size is aimed at by the voice coil of phi2.5cm caliber, the magnetic circuit which took the measures against vibration isolation, etc.

The newly developed EMIT-R tweeter is carried in the high region.
The technology of the EMIT tweeter which is technology original with Infiniti is inherited, a plane diaphragm 3cm in diameter is driven by the powerful magnetic field, and the Tran Gent nature, the low distortion, and the broadband play which were excellent with this are enabled.

In order to eliminate phase dirt, the phase of low-pitched sound and a loud-sound unit is arranged by adopting a stage-like baffle, and faithful time alignment is aimed at by the design of the still more precise crossover network.

Careful selection materials, such as a special polypropylene capacitor, are adopted as a network part.
Furthermore, the protection circuit is carried in order to cope with an excessive unusual incoming signal.

The ABS synthetic resin material which suppressed the unnecessary vibration is adopted as enclosure, and the dumping material of a rubber system is adopted as the lower part and the grill perimeter.
Moreover, the wall tapestry public-funds implement attachment is prepared in the back.

With combination with an optional Infiniti simal subWoofer, a 40Hz super-low-pass play is attained.
