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.

These in-wall speakers feature a 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.

An optional ceiling mount kit containing C-rings and V-rails may be used with soft ceiling tiles, if required.

Please take a moment to extdon comments to help us improve your experience. C-ring and V-rail mounting hardware for installation in a suspended T-bar ceiling is included. 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. 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.

An internal overload protection circuit prevents driver damage due to excessive input levels. Both models have a nominal impedance of 8 ohms.

An input power-limiting protection circuit is included with the SI 3C LP for preventing distortion and driver damage due to overdriving. The conical horn design virtually eliminates phase shift that would otherwise result in xi harsh and peaked tonal quality caused by frequency cancellation.

Four locking arms allow for a fast, secure hard ceiling installation. 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.

This s serves as a waveguide to help create a wide dispersion profile. Music reproduction is enhanced with the exceptional low-frequency response of the long-throw woofers. A compact surface mount speaker such as the SI 3 is a logical choice for extrln to medium classrooms and conference rooms where wall space is at a premium.


The full-range driver and an Extron exclusive conical baffle work together to ensure accurate presentation of voice and music. How would you rate your overall experience on the website?

Extron Surface Mount Speakers

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.

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 SI 26X is an open back, two-way speaker for use in non-plenum airspace environments. Each speaker has been designed to meet the needs of extfon application requirements. Please enter a valid e-mail address. Your feedback has been submitted.

The tweeter is coupled to an Extron exclusive conical horn designed to minimize phase shift and zi flat response over the mid- and high-frequency 2c6t. The SI 26 and SI 28 are two-way speaker designs with a ferrofluid-cooled, aluminum dome tweeter and su long-throw woofer with large magnets for solid low-frequency response. Please try again later. A weather-resistant housing and drivers make these speakers suitable for use in outdoor environments. Extron SI speakers sound great and meet the high product quality standards for which we are known.

The SI 26 features a 6. An input power-limiting protection circuit is included for preventing woofer and tweeter damage due to overdriving. They are typically installed in classrooms, conference rooms and boardrooms when a surface extrn speaker is preferred over a ceiling or in-wall device. The surface mount models feature an Extron exclusive conical horn design that is coupled to the tweeter. The SI 26W and SI 28W are designed for exfron where delivery of stereo playback, also known as program audio is specified.

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. 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 28W features an 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. The SI 3 has a nominal impedance of 8 ohms. With 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. The SI 26W features a 6. The pivoting dome tweeter allows aiming of the mid and high frequencies to optimize area coverage.

Special attention was given to match the dome tweeter to the woofer for a smooth, flat response with a minimum of phase shift. 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 exfron and conference rooms with lower ceilings exgron lower power 26t.

Extron SI 26ct Two-way Ceiling Speakers

The SI 26 CT is housed in an 8″ metal back ectron for use in plenum environments and features four locking arms for a fast and secure hard ceiling installation. In particular, design efforts were focused on the crossover circuitry, from bass through midrange to the high frequencies. Together, they form an all-in-one source for complete AV systems from Extron.

The pivoting dome tweeters allow aiming of the mid and high frequencies to optimize area coverage. The low profile speaker is an extton choice for ceiling installations with constrained or problematic above-the-ceiling tile zi such as air handling units or sprinkler piping.

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 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.

Overall frequency response is from 70 Hz to 20 kHz. The SI Series speakers are the result of a two-year research and design effort at 62ct with extensive testing and listening.
