The Altec 405A Speaker is an extremely shallow, very compact 4" speaker
that provides true high fidelity reproduction. Using an Indox V magnet
with a flux density of 10,250 gauss, the damped, high compliance cone pro­
vides low frequency reproduction and smooth, extended frequency response
equal to most larger speakers. The compact size of the 405A Speaker makes
it ideal for public address systems in airports, buses, ships, aircraft, church
pews and any installation that has need for a low level distribution system
for wired music, program distribution and paging systems. Very smooth dis­
tribution is provided over a wide angle of 90° without high frequency loss.
The wide angle of distribution, plus the small size of the unit allows greater
separation between speakers with a substantial savings in speakers required.
Clear, intelligible speech and good music reproduction is assured because
of the extended 60 to 15,000 Hz range.
Made of heavy grade steel, the entire 405A unit is designed for continuous,
trouble-free service. The small size of the speaker, 4%" square by 214" deep
make it possible to either front mount or rear mount the speaker in wall, par­
titions or ceilings and into volumes as low as 0.1 cubic feet. The solid, welded
construction and water-resistant cone of the 405A prevents distortion in areas
of high humidity.
In line with other Altec speakers, the famed experience and engineering
"know-how" has been built into the 405A Speaker, to make it the highest
quality 4" loudspeaker available.
