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.

Music reproduction is enhanced with the exceptional low-frequency response of the long-throw woofer. Bass is optimized using a tuned port for improved low-frequency response. The pivoting dome tweeter allows aiming of the mid and high frequencies for best area coverage, and matches the high power capability of the woofer with enhanced midrange and high-frequency response for high ceiling applications. The overall frequency range for the SI 26CT is 70 Hz to 20 kHz.

This System INTEGRATOR® Series speaker is ideally suited for overhead distributed audio applications for music and voice in conference rooms, lecture halls, auditoriums, and other high-ceiling venues requiring high power, plenum-rated ceiling speakers.

SI 26CT speakers are sold in pairs and include a 5 year parts and labor warranty.

The SI 26CT offers both direct 16 ohm or 70/100 volt operation with a behind-the-grille, five position power selector switch. In the 16 ohm direct mode, an input power limiting protection circuit is included for preventing woofer and tweeter damage due to overdriving.

For room balancing with 70/100 volt systems, the behind-the-grille power selector switch allows for 60, 30, 15, and 7.5 watt settings in 70 volt operation and 60, 30, and 15 watt settings for 100 volt operation.

The SI 26CT features four locking arms for a fast and secure hard ceiling installation. C-ring and V-rail mounting hardware for installation in a suspended T-bar ceiling is included. The SI 26CT features a white grille and bezel that can be painted to match the architectural elements of the environment.
