Conical Baffle

In small to medium-sized classrooms with low ceilings, midrange and high frequencies are likely to be confined or "beamed" within an area directly beneath each ceiling speaker. As a result, some listeners will hear the audio clearly while others may not.

To address this issue, the SI 3CT LP has been designed with a 3" full-range driver that is acoustically coupled to an Extron exclusive conical baffle. This baffle serves as a waveguide to help create a wide dispersion profile of 170°. With this very broad conical spreading of the mid and high frequencies, a system of SI 3CT LP speakers will ensure consistent volume levels for everyone in the room while delivering increased intelligibility and accurate music reproduction.

Low Profile Back Can

The SI 3CT LP features a special 4" low profile back can for installation in plenum ceilings where the presence of HVAC ducting, fire sprinkler piping, or limited spacing above the suspended ceiling would hamper placement of a ceiling speaker with a more conventional back can such as the SI 26CT. The specially designed 3" full-range driver of the SI 3CT LP works together with the low profile back

can to deliver wide frequency response as well as wide conical dispersion for optimal sound reproduction in classrooms and other environments.
