Applications
The Control 26-DT is a compact
ceiling speaker assembly configured to
install into standard ceiling backcans
designed for 200 mm (8 in) speakers.
High power handling, wide frequency
response and low distortion make the
Control 26-DT ideal for sound systems
requiring a higher fidelity sound, that
integrates with many backcan designs.
The Control 26-DT includes a high
quality, low insertion-loss transformer
for use with 70.7 V and 100 V
distributed line systems. The transformer has a top tap rating of 60 W.
The Control 26-DT is designed to
match industry standard mechanical
specifications for 8-inch speakers. The
four mounting points, at a diameter of
194 mm (7.625 in), allow mounting
either to a grille or a backcan, depending on the equipment used.
The 165 mm (6.5 in) woofer features
a polypropylene-coated cone and pure
butyl-rubber surround for long life,
even in high humidity environments.
The coaxially mounted 19 mm
(3/4 in) titanium coated tweeter
provides crisp, clear highs. Diffractionloading of the tweeter provides wide,
even coverage of the listening area.
The defined 90° coverage pattern
provides excellent projection for use in
medium-height ceilings.
