The Control
®
28 is the largest of
JBL Professional’s Control Contractor
Series indoor/outdoor loudspeakers.
Its rich sonic character makes the
Control
®
28 a perfect choice for
restaurants, health clubs, under bal-
cony, outdoor theme & water parks,
or other applications where fore-
ground/background music and pag-
ing are required.
The unique and global patent
pending InvisiBall™ mounting hard-
ware is included in each system and
makes short work of permanent
installation. The InvisiBall™ mounting
method adds the benefit of vertical
rotation of up to 37° off-axis and hor-
izontal rotation of up to 44° off-axis.
Because InvisiBall™ adjustments are
made through a hidden access
behind the logo badge, the grill
never needs to be removed and there
exists a high degree of theft deter-
rence as well.
The Control
®
28 readily accepts a
variety of paints and finishes to
match any decor.
Weather resistance is maximized by
coating the woofer cone in
polypropylene and terminating its cir-
cumference in JBL’s WeatherEdge™, a
seamless, rubberized extension of the
woofer surround that provides added
protection to critical transducer ele-
ments. The polycarbonate tweeter
diaphragm is reinforced with a thin
film of titanium for added rigidity and
endurance against sun, salt and mois-
ture. Zinc plated grilles resist rusting
in the harshest conditions.
Available in black (Control 28) and
white (Control 28-WH).
