The full-range driver and an Extron exclusive conical baffle work together to ensure accurate presentation of voice and music. In 8 ohm operation, these speakers are designed for use with our MPA Integrated Mini Power Amplifier in small to medium low ceiling classrooms requiring two to four wide dispersion speakers for maximum room coverage. The pivoting dome tweeter allows aiming of the mid and high frequencies to optimize area coverage.

The SI 26X is designed for 8 ohm direct connection to small or large audio power amplifiers, and may be connected for series or parallel operation. They are typically installed in classrooms, conference rooms and boardrooms when a surface mount speaker is preferred over a ceiling or in-wall device. 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 26X is an open back, two-way speaker for use in non-plenum airspace environments.

The larger SI 28 features an 8″ woofer, a 1″ dome tweeter, 90 watts continuous pink noise or watts continuous program capacity, and frequency response from 50 Hz to 20 kHz. 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.

A weather-resistant housing and drivers make these speakers suitable for use in outdoor environments. It is available with a black or white finish that can also be painted to match the environment.

Four locking arms allow for a fast, secure hard ceiling installation. A 1″ pivoting ferrofluid-cooled, titanium-coated dome tweeter matches the high power capability of the woofer with enhanced midrange and high extronn response for high ceiling applications. Special attention was given to match the dome tweeter to the woofer wi a smooth, flat response with a minimum of phase shift. Voice reproduction from documentaries and live microphones is natural and clear sounding.


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

In particular, design efforts were focused on the crossover circuitry, from bass through midrange to the high frequencies. 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.

The SI 26 features a 6. The SI 28W features so 8″ long-throw woofer, a 1″ dome tweeter, 35 watts continuous pink noise or 70 watts continuous program capacity, a frequency response from 30 Hz to 20 kHz, and a nominal impedance of 8 ohms. Long-throw woofers are coupled to pivoting dome tweeters to deliver accurate voice and music reproduction, as well as wide angle sound dispersion for higher ceiling and power applications.

How would you rate your overall experience on the website? IP Link Control Processors. Both models have a nominal impedance of 8 ohms.

The SI 26W and SI 28W are designed for environments where delivery of stereo playback, also known as program estron is specified.

An internal overload protection circuit prevents driver damage due to excessive input levels. Your feedback has been submitted. A compact surface mount speaker such as the SI 3 is a logical choice for small to medium classrooms and conference rooms where wall space is at a premium.

Together, they form an all-in-one source for complete AV systems from Extron. Overall frequency response is from 70 Hz to 20 kHz.

Extron SI 26ct Two-way Ceiling Speakers

C-ring and V-rail mounting hardware for installation in a suspended T-bar ceiling is included. These in-wall speakers feature a proprietary crossover design from the woofer xetron the dome tweeter, to provide a smooth transition from low to mid and high frequencies, so that voices are natural and clear sounding. This baffle serves as a waveguide to help create a wide dispersion profile. 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 pivoting dome tweeters allow aiming of the mid and high frequencies to optimize area coverage. Extron SI speakers sound great and meet the high product quality standards for which we are known.


The SI 26W features a 6.

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. The SI Series speakers are the result of a two-year research and design effort at Extron with extensive testing and listening.

The SI 26 and SI 28 incorporate a precision engineered crossover design that assures a smooth transition from bass to midrange and 226ct frequencies, delivering optimum voice and music reproduction. The SI 3 has a nominal impedance of 8 ohms. Each speaker has been designed to meet the needs of specific application requirements. The surface mount extrkn feature an Extron exclusive conical horn design that is coupled to the tweeter.

The conical horn design virtually eliminates phase shift that would otherwise result in a harsh and peaked tonal quality caused by frequency cancellation. Music reproduction is enhanced with the exceptional low-frequency response of the long-throw woofers.

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. Overall frequency response is 50 Hz to 20 kHz. An input power-limiting protection circuit is included with the SI 3C LP for preventing distortion and driver damage due to overdriving.

Exyron this new conical horn design, harsh tonal qualities due to cancellation in portions of the frequency range caused by phase shifting are all but eliminated. An input power-limiting protection circuit is included for preventing woofer and tweeter damage due to overdriving.

Exhron are available with a black or white finish that can also be painted to match the environment. 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 for solid low-frequency response. The low profile speaker is an excellent choice for ceiling installations with constrained or problematic above-the-ceiling tile issues xi as air handling units or sprinkler piping.

With this very broad conical spreading of the mid and high frequencies, two SI 3 speakers in a small to medium classroom should ensure consistent volume levels for everyone while delivering increased intelligibility and accurate music reproduction.
