The ALTEC 807-8A and 808-8A High-Frequency Driver Loudspeakers are designed for all professional

PLAYBACK applications requiring outstanding reproduction of sound over an extremely wide frequency

range at substantial Fюwer levels. Such conditions are readily fulfilled with unusually high efficiency and

exceptionally uniform response from 500 or 800 Hz (dependent on the dividing network and horn employed}

to over 20,(X)0 Hz.

When used in conjunction with the ALTEC 511A, 51 IB (500 Hz) or 81 IB (800 Hz) sectoral horn, the

N501-8A (500 Hz) or N801-8A (8(Ю Hz) network, and the 414, 515 or 416-8A low-frequency loudspeaker,

the 807-8A and 808-8A furnish the realistic reproduction demanded by all major broadcasting stations, re

cording studios, theatres, auditoriums and music halls.

Both the 807-8A and 808-8A transducers utilize a voice coil of notably large diameter (1-3/4"), edge wound

with aluminum ribbon and coupled to a large diaphragm. A mechanical phasing plug (i.e., pole

piece), having two exponential acoustic slots, is utilized to provide the proper phase relationship between the

sound emanating from the center and outer edges of the diaphragm and voice coil assembly, thus ensuring

maximum high-frequency reproduction while maintaining a smooth overall response. Either driver is capable

of uniform, peak-free reproduction to a point far above the range of human hearing. The entire diaphragm

and voice coil assembly of the 807-8A and 808-8A is field replaceable; no special tools are required.

For full range systems utilizing low-frequency loudspeakers of relatively low efficiency, located in non-

reverberant areas having moderate ambient noise levels, the 807-8A driver proves a perfect match. (Such

conditions would be analagous to the average listening room or smaller broadcast and recording studio.)

In instances wherein relatively high ambient noise is present, and where maximum efficiency of both vocal

speech and music must be reproduced with great clarity, the heavier magnet weight and greater flux density

of the 808-8A are preferred. The 808-8A represents one of the finest high-frequency transducers manu

factured by ALTEC; the 2 dB greater efficiency (over the 807-8A), coupled with the same precision accuracy

of minute production tolerances, make the 808-8A the industry standard for laboratory and professional

usage alike.

These factors, together with the all-important ALTEC criteria of engineering experience, combine to produce

the 807-8A and 808-8A high-frequency loudspeakers of virtually matchless quality and limitless application.
