ALTEC LANSING 620A Monitor
358,500 yen(around the one-set and 1977 time)
The monitor speaker system which adopted 604-8G which is a coaxial composite-construction unit.

604-8G which is a 38cm same axle type unit of 604 series is adopted as a unit.
Horn Sloat for inside loud sounds is prepared in the form which penetrates the magnetic circuit for low-pass, and the acoustic image of the coaxial composite construction adopted as this unit corresponds on an axial center by the multi-seller phone of an exclusive design. Furthermore, consideration is carried out so that phase difference before and behind a diaphragm may be made into the minimum.
IIn 604-8G, improvement in the wide-range characteristic and transient response characteristic is aimed at for the merit of the sound of the conventional alloy diaphragm integral-type edge by the weight saving of the oscillating mass as it is.

The enclosure is bass-reflex structure and serves as bright oak finishing.
Moreover, clear-cut Brown's mesh grill is used for the saran network.

ALTEC LANSING Model 9861
690,000 yen(around the 1985 time)
The large-sized speaker system packed into the walnut cabinet which improves based on "voice of the theater" A7-X, and matches a crossing-home terrier.

411-8A is carried in low-pass.
The long travel voice coil with an aperture of 10cm is driven by the magnetic circuit with a weight of 8.2kg.

Driver 902-8A and a sectoral horn 811B are carried in the inside region.
902-8A is a ferrite type of 902-8G, and has adopted the tangerine phase plug.
Moreover, reinforcement is doubly carried out with the flange and three sections with which 811B is characteristic. Furthermore, the resonance and resonance of the phon are suppressed by using special alloy die-casting.

MR-902 tweeter of an establishment meter is carried in the high region.
Manta Leh Horne was employed as the phon part, and the problem of the phon tweeter that directional characteristics become beam-like is canceled as frequency rises.
Thereby, directional characteristics realized the 10kHz cone type of 65 ", and have secured the large service area.

The frontloading type bass-reflex cabinet in which the top engineer of ALTEC performed adjustment by Hearing impression is adopted as the enclosure.
Detailed tuning is given to the bass-reflex port part, and the flow and resonance sound of air of a bass-reflex port part are controlled.

System 3 ways, a 3 speaker all phone + bass-reflex system, and a floor type
Use unit etc. For low-pass: Corn type (411-8A)
For inside regions: Phon type (902-8A+811B)
