Extron SI 26ct Two-way Ceiling Speakers | eBay

A weather-resistant housing and drivers make these speakers suitable for use in outdoor environments. An optional ceiling mount kit containing C-rings and V-rails may be used with soft ceiling tiles, if required. Together, they form an all-in-one source for complete AV systems from Extron.

Voice reproduction from documentaries and live microphones is natural and clear sounding. IP Link Control Processors. Music reproduction is enhanced with the exceptional low-frequency response of the long-throw woofers. In particular, design efforts were focused on the crossover circuitry, from bass through midrange to the high frequencies.

Special attention was given to match the dome tweeter to the woofer for a smooth, flat response with a minimum of phase shift.

The conical horn design virtually eliminates phase shift that would otherwise result in a harsh and peaked tonal quality caused by frequency cancellation. Both models have a nominal impedance of 8 ohms. 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 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 26W and SI 28W are designed for environments where delivery of stereo playback, also known as program audio is specified.

Extron Surface Mount Speakers

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 Series speakers are the result of a two-year research and design effort at Extron with extensive testing and listening. An input power-limiting protection circuit is included with the SI 3C LP for preventing distortion and driver damage due to overdriving. The SI 3C LP and SI 3CT LP have a single full-range driver featuring a very wide dispersion pattern exrron full-range frequency response specifically for small to medium classrooms and conference rooms with lower ceilings and lower power requirements.

The pivoting 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.

The SI 26 and SI 28 incorporate a precision engineered crossover design that assures a smooth transition from bass to midrange and high frequencies, 26ctt optimum voice and music reproduction. Long-throw woofers are coupled to pivoting dome tweeters to deliver accurate voice and music reproduction, as well as wide angle sound dispersion for eztron ceiling and power applications.

It is available with a black or white finish that can also be painted to match the environment.

The SI 26 features a 6. 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. 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.

26cr Your feedback has been submitted. An input power-limiting protection circuit is included for preventing woofer and tweeter damage due to overdriving.


This baffle serves as a waveguide to help create a wide dispersion profile.

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 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 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. With high power capability of 25 watts continuous pink noise or sii watts continuous program capacity, the SI 26X is an ideal choice for great sound in moderate to high ceiling applications. 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.

The SI 26W features a 6. The SI 3 is a surface mount speaker that is extorn in size, yet is surprisingly wide, smooth frequency response for faithful sound reproduction of a wide range of audio material. An internal overload protection circuit prevents driver damage due eztron excessive input levels.

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 3 features an incredibly wide frequency response of 75 Hz to 18 kHz, and 16 watts extroon pink noise and 32 watts continuous program capacity. Please enter a valid e-mail address.
