Bonjour à tous,
Voici la configuration d'origine avec les 817....
ALTEC LANSING Mantarayhorn+817A System
This is a speaker system using the Mantare horn developed by Altec.
The Mantarayhorn + 817A system is one of Altech's theatrical speaker systems named Voice of the Theater.
The system consists of a front load horn with a double woofer in the low range and a man-tale-horn in the high range. The unit used depends on the time of sale.
There are two 40 cm cone type woofers in the lower range. They used 515C initially and were changed to 515E in 1981.
A horn type unit that combines a driver unit and a Man-Tale-horn MR94 is installed in the high range.
The driver unit used 288-16H initially and was changed to 288-16K in 1981, and the manta ray Rayhorn was changed from MR94 to MR94A MR94A later.
The enclosure is 817A, an enclosure for double woofer.
The 817A is a combination of front load horn and bass reflex system. The front load horn loads the woofer up to 150 hz and the bass reflex port extends the low end up to 50 hz.
