847A Seville

A speaker system that is compact without losing the playback sound and design of a large system.

There are 2 types of Woofer of 847A, the former type of 16 Ω specification and the latter type of 8 Ω specification. The model was changed in 1970.
In Japan, there were 2 variations using the Altec original cabinet and the designated domestic cabinet. Also, as for the domestic cabinet, it seems to be sold separately.

In the previous fiscal year, we installed a 30 cm cone woofer 414A in the lower range, a horn unit 3000H with a zinc die-cast phone in the higher range, and an N-3000E network.

In the latter stage, 30 cm cone type woofer 414-8B is mounted in the low range.
Other configurations are the same as the previous year, with a horn type unit 3000H and network N-3000E.

The cabinet uses a bass reflex system.
