weather-resistant performance.

For optimum acoustic and application versatility, Model FA138 has been engi-

neered as a system with matched enclosure Model FA97-8, choice of trans-

formers and grilles. (For detailed information on accessories, refer to SL1-

ventional screws. Loudspeaker front-loads into the enclosure and includes a

neoprene rubber gasket on the back of the speaker basket to seal the assem-

bly and optimize the low frequency response. It may also be mounted into a

wall or ceiling of minimum depth by using plaster/mounting ring Model FAPR-8.
