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
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
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.
characteristics realized the 10kHz cone type of 65 ", and have secured the large
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.
