SI 26CT
Two-Way Ceiling Speakers with 8" Back Can and 70/100 V Transformer
Description
The Extron SI 26CT is a high power, two-way ceiling speaker featuring a coaxial dual driver
design, transformer, and an 8" (20.3 cm) metal back can. The SI 26CT is ideal for plenum
installations in large classrooms, lecture halls, and auditoriums. A 6.5" (16.5 cm) long-throw
woofer coupled to a 1" (2.5 cm) pivoting titanium-coated dome tweeter delivers accurate voice
and music reproduction, as well as wide angle sound distribution. Special consideration is
given to the crossover from the woofer to the tweeter, providing a smooth transition from low
to mid frequencies. Voice reproduction from documentaries and live microphones is natural
and clear sounding.
