SF 26X

The Extron SI 26X is a two-way ceiling speaker featuring an open back and coaxial dual driver design for use in non-plenum airspace environments. A 6.5" (16.5 cm) long-throw woofer coupled to a 3/4" (1.9 cm) pivoting titanium-coated dome tweeter delivers accurate voice and music reproduction, as well as wide angle sound distribution. Wide dispersion characteristics make for a good choice in low ceiling applications. 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, which is specifically designed for infinite baffle environments, and provides an efficient low end response down to 50 Hz. The pivoting dome tweeter allows aiming of the mid and high frequencies for best area coverage and proper imaging. The overall frequency range for the SI 26X is 50 Hz to 20 kHz.

This System INTEGRATOR® Series speaker is ideally suited for overhead distributed audio applications for music and voice in classrooms, conference rooms, and boardrooms.

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

The SI 26X is designed for 8 ohm direct connection to power amplifiers, and may be connected for series or parallel operation. Four locking arms allow for a fast, secure hard ceiling installation. An optional C-ring and V-rail kit is available for use with soft ceiling tiles. The SI 26X features a white grille and bezel that can be painted to match the architectural elements of the environment.
