Please enter a valid e-mail address. The extfon dome tweeter allows aiming of the mid and high frequencies to optimize area coverage. By installing them into the walls, these speakers provide a low-profile appearance while also deterring theft.

Overall frequency response is 50 Hz to 20 kHz. The SI 26 CT is housed in an 8″ metal back sk for use in plenum environments and features four locking arms for a fast and secure hard ceiling installation. 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 for solid low-frequency response. Special attention was given to match the dome tweeter to the woofer for a smooth, flat response with a minimum of phase shift. 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.

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. It is available with a black or white finish that can also be painted to match the environment. The SI 3 is a surface mount speaker that is compact in size, yet delivers surprisingly wide, smooth frequency response for faithful sound reproduction of a wide range of audio material.

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. Please take a moment to provide comments to help us improve your experience.

Voice reproduction from documentaries and live microphones is natural and clear sounding. The SI 3 has a nominal impedance of 8 ohms. Overall frequency response is from 70 Hz to 20 kHz. Both models have a nominal impedance of 8 ohms. Music reproduction is enhanced with the exceptional low-frequency response of the long-throw woofers.


The SI 26 features a 6. They are typically installed in classrooms, conference rooms and boardrooms when a surface mount speaker is preferred over a ceiling or in-wall device. 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. The pivoting dome tweeters allow aiming of the mid and high frequencies to optimize area coverage.

How would you rate your overall experience on the website? Four locking arms allow for a fast, secure hard ceiling installation. This baffle serves as a waveguide to 2ct create a wide dispersion profile. Your feedback has been submitted. eextron

To address the issue of beaming in the midrange and high frequencies that can be found in a small, compact speaker, the 26ch 3 has been designed with a 3″ 7. The SI 26W and SI 28W are designed for environments where delivery ai stereo playback, also known as program audio is specified.

An internal overload protection circuit prevents driver damage due to excessive input ectron. They are available with a black or white finish that can also be painted to match the environment. The SI 26W features a 6.

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. C-ring and 26cf mounting hardware for installation in a suspended T-bar ceiling is included. Long-throw woofers are coupled to pivoting dome tweeters to deliver sxtron voice and music reproduction, as well as wide angle sound dispersion for higher ceiling and power applications.

Extron SI speakers sound great and meet the high product quality standards for which we are known. An input power-limiting protection circuit is included for preventing woofer and tweeter damage due to overdriving. In particular, design efforts were focused on the crossover circuitry, from bass through midrange to the high frequencies.

Etron SI Series speakers are the result of a two-year research and design effort at Extron with extensive testing and listening. IP Link Control Processors. The low profile ectron is an excellent choice for ceiling installations with constrained or problematic above-the-ceiling tile issues such as air handling units or sprinkler piping.

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 conical horn design virtually eliminates phase shift that would otherwise result in a harsh and peaked tonal quality caused by frequency cancellation.

Please try again later. A 1″ pivoting ferrofluid-cooled, titanium-coated dome tweeter matches the high power capability of the woofer with enhanced midrange and high frequency response for high ceiling applications. Each speaker has been designed to meet the needs of specific application requirements. 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.

An optional ceiling mount kit containing C-rings and V-rails 26vt be used with soft ceiling tiles, if extdon. The full-range driver and an Extron exclusive conical baffle work together to ensure accurate presentation of voice and music.

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 SI 28W features an 8″ long-throw woofer, a 1″ dome tweeter, 35 watts continuous pink noise or 70 watts continuous program capacity, a 26ft response ssi 30 Hz to 20 kHz, and a nominal impedance of 8 ohms.

The SI 26 and SI 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. 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.

The SI 26CT features a zi power design extrom 75 watts continuous pink extrn or watts continuous program capacity for use in larger classrooms, lecture halls, and auditoriums.

An input power-limiting protection circuit is included with the SI 3C LP for preventing distortion and driver damage due to overdriving. 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.
