SM 28

The Extron SI 28W two-way in-wall speaker features a ferrofluid-cooled, titanium-coated dome tweeter and a long-throw woofer to deliver balanced voice and music reproduction. Special consideration is given to the crossover from the woofer to the tweeter, to provide a smooth transition from low to high frequencies. Voice reproduction from documentaries is natural and clear sounding. Music reproduction is enhanced with the exceptional low-frequency response of the long-throw woofers. The pivoting dome tweeter allows aiming of the mid and high frequencies for best area coverage.

This System INTEGRATOR® Series speaker is ideally suited for program audio applications in AV installations including boardrooms, classrooms, and conference rooms where speakers must be low profile and mounted into the walls. This speaker is packaged and sold in pairs and includes a 5 year parts and labor warranty.

The SI 28W features an 8" (20.3 cm) long-throw woofer, a 1" (2.5 cm) tweeter, 35 watts continuous pink noise and 70 watts continuous program capacity, and a frequency range from 30 Hz to 20 kHz.

This speaker has a nominal impedance of 8 ohms and offers a theft-deterrent, permanently installed, in-wall design. The SI 28W features a white grille and bezel that can be painted to match the architectural elements of the environment.
