Professional Series – Background/Foreground Ceiling Speaker
SPECSHEET
Off Axis Frequency Response (1/3 Oct Avg):
Measured on-axis with a distance referenced to 1 meter at 1 watt;
shown as a half-space (2pi) environment
Frequency Response:
Input connection is conveniently provided on a removable locking
connector (included), providing secure connection via screw-down
terminals and allowing a system to be prewired before installing the
speaker for fast snap-on convenience. Separate connector terminals
are available for the input and for the loop-through wires, making it easy
to jumper the speaker signal to additional speakers. The input terminal
plate provides strain relief for either bare wire, plenum cable or ½ inch
conduit (12 mm I.D.). The terminal box is securely enclosed to meet
safety codes.
The speaker trim and grille are paintable to match any decor. A paint
shield is provided for covering the drivers while painting the rim.
Installation of the Control 26C is quick and easy. The loudspeaker is
packaged complete with the backcan, grille, support backing bracket
and tile rails.
The entire installation can be accomplished without requiring access
above the ceiling. A template is provided for marking the cutout. An
innovative C-shaped support backing plate can be installed from below
through the cutout to reinforce the top of the ceiling material. Tile bridge
rails are included which can be screwed onto the C-plate to extend
support to the T-channel grid in suspended ceiling installations. After the
speaker is fitted through the cutout, it is held securely in place via three
mounting tabs which tighten onto the C-plate, if used, or directly onto
the ceiling material.
The Control 26C backcan is made of formed steel and the speaker is
suitable for use in air handling spaces, per U.L.-2043. An attachment
loop is provided on the backcan for cabling to the building structure as a
secondary support in seismic areas or where required by code.
The model Control 26CT includes a 60W multitap transformer for use
in either 70.7V or 100V distributed-line systems. The transformer
effectively limits the power to the speaker, so SonicGuard is not included
in the Control 26CT. Taps are selected with a rotary switch conveniently
located on the front panel, but protected under the grille, so that the
speaker does not have to be removed to adjust tap settings.
All JBL Control Contractor loudspeakers—both ceiling speakers and
surface-mount models—are designed with a similar sonic signature,
allowing for mixing and matching of the various models within an
application, providing a similar tonal character throughout the entire
listening area.
