descriptionspecifications

The Extron SI 26 two-way surface mount speaker features a ferrofluid- cooled, aluminum dome tweeter coupled to an Extron exclusive, new conical horn design for minimum phase shift and a flat response over the mid- and high-frequency ranges. Harsh tonal qualities due to cancellation in portions of the frequency range caused by phase shifting are all but eliminated with this new conical horn design. A long-throw woofer with large magnets provides solid low-frequency response. A new approach to crossover design assures a smooth transition from bass through midrange to the high frequencies, delivering optimum voice and music reproduction. An input power- limiting protection circuit is included for preventing woofer and tweeter damage due to overdriving.

This System Integrator Series speaker is ideally suited for classrooms, conference rooms, and boardrooms, and with a weather-resistant construction, is at home in outdoor environments.

The SI 26 features a 6.5" (16.5 cm) long-throw woofer, a 1"

(2.5 cm) tweeter, 150 watts continuous program capacity, and frequency response from 70 Hz to 20 kHz. This speaker has a nominal impedance of 8 ohms with a durable, high-impact housing.

Included with the SI 26 is Extron’s exclusive patent pending V-Lock mounting hardware, which facilitates easy, secure installations and allows for wide 60° horizontal and 55° vertical travel.

The SI 26 is sold in pairs and is available in a black or white finish, and includes a 5 year parts and labor warranty.
