System Integrator® Speakers | Extron

A 1″ pivoting ferrofluid-cooled, titanium-coated dome tweeter matches the high 226ct capability of the woofer with enhanced midrange and high frequency response for high ceiling applications. In 8 ohm operation, these speakers are designed for use with our MPA Integrated Mini Power Extton in small to medium low ceiling classrooms extton two to four wide dispersion speakers for su room coverage. With this new conical horn design, harsh tonal qualities due to cancellation in portions of the frequency range caused by phase xi are all but eliminated.

An internal overload protection circuit prevents driver damage due to excessive input levels. IP Link Control Processors. With high power capability of 25 watts continuous pink noise or 50 watts continuous program capacity, the SI 26X is an ideal choice for great sound in moderate to high ceiling applications.

Special attention was given to match the dome tweeter to the woofer for a smooth, flat response with a minimum of phase shift. In particular, design efforts were focused on the crossover circuitry, from bass through midrange to the high frequencies.

The SI 3 features an incredibly wide frequency response of 75 Hz to 18 kHz, and 16 watts continuous pink noise and 32 watts continuous program capacity. In the 16 ohm direct mode, an input power limiting protection circuit is included for preventing distortion as well as potential woofer and tweeter damage if the speakers are overdriven.


The full-range driver and an Extron exclusive conical baffle work together to etxron accurate presentation of voice and music. A weather-resistant housing and drivers make these speakers suitable for use in outdoor environments.

The SI 26 CT is housed in an 8″ metal back can for use in plenum environments and features four locking arms for a fast and secure hard ceiling installation. Long-throw woofers are coupled 2ct pivoting dome tweeters to deliver accurate voice and music reproduction, as well as wide angle sound dispersion for higher ceiling and power applications. The SI 3 has a nominal impedance of 8 ohms. These in-wall speakers feature s proprietary crossover design from the woofer to the dome tweeter, to provide a smooth transition from low to mid and high frequencies, so that voices are natural and clear sounding.

The low profile speaker is an excellent choice for ceiling installations with constrained or problematic above-the-ceiling tile issues such as air handling units or sprinkler piping. C-ring and V-rail mounting hardware for installation in a suspended T-bar ceiling is included.

The SI Series speakers are the result of a two-year research and design effort at Extron with extensive testing and listening. Your feedback has been submitted. Overall frequency response is from 70 Hz to 20 kHz. The SI 26W features a 6. To address the issue of beaming in the midrange and high frequencies that can be found in a small, compact speaker, the SI 3 has been designed with a 3″ 7.

The SI 26CT features a high power design of 75 watts continuous pink noise or watts continuous program capacity for use in larger classrooms, lecture halls, and auditoriums. Please try again later. The pivoting dome tweeter allows aiming of the mid and high frequencies to optimize area coverage. The SI 26 and 26cct 28 incorporate a precision engineered crossover design that assures a smooth transition from bass to midrange and high frequencies, delivering optimum voice and music reproduction.


By installing them into the walls, these speakers provide a low-profile appearance while also deterring theft.

Extron SI 26ct Two-way Ceiling Speakers

Overall frequency response is 50 Hz to 20 kHz. Four locking arms allow for a fast, secure extrln ceiling installation. Extron SI speakers sound great and meet the high product quality standards for which we are known. The surface mount models feature an Extron exclusive conical horn design that is coupled to the tweeter.

Both models have a nominal impedance of 8 ohms. An optional ceiling mount kit containing C-rings and V-rails may be used with soft ceiling tiles, if required.

The SI 3C LP and SI 3CT LP have a single full-range driver featuring a very wide dispersion pattern and full-range frequency response specifically for small to medium classrooms and conference rooms with lower ceilings and lower power requirements.

The tweeter is coupled to an Extron exclusive conical horn designed to minimize phase shift and deliver flat response over the mid- and high-frequency ranges.

The SI 26X eztron designed for 8 ohm direct connection to small or large audio power amplifiers, and may be connected for series or parallel operation. An input power-limiting protection circuit is included for preventing woofer and tweeter damage due to overdriving.

Extron Surface Mount Speakers

The SI 26 features a 6. The pivoting dome tweeters allow aiming of the mid and high frequencies to optimize area coverage. They are available with a black or white finish that can also be painted to match the environment.

They are two-way designs featuring a ferrofluid-cooled, titanium-coated dome tweeter and a long-throw woofer in a vertically stacked arrangement to deliver balanced voice and music reproduction. The SI 26 and SI 28 are two-way speaker designs with a ferrofluid-cooled, aluminum dome tweeter and a long-throw woofer with large magnets extroh solid low-frequency response.
