When Installing the Unit
• Install a speaker only in stable locations, and make
appropriate arrangements to prevent it from falling down
or rolling cross the floor. If it falls down or moves, this
may cause personal injury and/or property damage.
• When unpacking or moving a heavy speaker, be sure to
handle the unit with two or more persons. Falling or
dropping the speaker may cause personal injury and/or
property damage.
When the Unit is in Use
• Do not stand or sit on, nor hang down from the speaker
as this may cause it to fall down or drop, resulting in
personal injury and/or property damage.
• Do not operate the speaker for an extended period of
time with the sound distorting. This is an indication of a
malfunction, which in turn can cause heat to generate
and result in a fire.

FEATURES
• The SR-F3 is a two-way full-range dual-amp-driven speaker system, and the SR-L3 is a sub-woofer system. Both
systems feature a high power handling capacity, high sound quality, and heavy-duty construction suited to both mobile
and permanent installation applications.
• Both speaker systems are designed to be used in conjunction with the dedicated controller.
• The SR-F3 houses a constant directivity (CD) horn that assures a uniform sound dispersion pattern of 60° horizontal by
30° vertical.
• The SR-F3 is equipped with a front-loaded horn with two 30 cm woofers.
• The SR-L3 employs two 46 cm woofers with a long voice coil.
• The SR-F3 has flying hardware (Aeroquip's ring/stud pan fitting) on both the top and the bottom, and an M16 nut on the
sides for attachment of an eye bolt.
• A light-weight, strong coniferous plywood enclosure is finished with extremely-durable epoxy paint.
• Input connectors are Nuetrik's NL4MPR and screw terminals. The SR-F3 is equipped with two Nuetrik connectors to
facilitate parallel connection.
• A woofer baffle is designed to permit easy woofer replacement without having to lay the speaker.
