Extron Conical Horn
Exclusive to the Extron SI 26 is a conical horn design that works in conjunction with the tweeter and phase plug to deliver minimal phase shift and flat frequency response over the midrange and high frequencies. Phase distortion is caused by a mismatch in dispersion patterns from the woofer and tweeter at the crossover frequency. This results in a harsh tonal quality characteristic of frequency cancellation caused by phase shifting.
The Extron conical horn acts as a waveguide to create a wide dispersion pattern for the tweeter that closely matches that of the woofer, so that frequencies from both drivers are smoothly merged together and the audio quality is improved and more natural-sounding. The phase plug further contributes to the flat frequency response and minimized phase shifting by working with the highest frequencies emanating from the tweeter to increase dispersion and reduce phase distortion.
Extron V-Lock Speaker Mounting System
Integrators are confronted with a number of challenges in the successful installation of surface mount speakers. To address these challenges, Extron has developed V-Lock, an exclusive, patent pending speaker mounting system, included with each SI 26 surface mount speaker.
V-Lock simplifies installation and substantially reduces the effort required to place and correctly position wall-mounted speakers, while also offering theft deterrence. V-Lock is comprised of two components, one that is mounted to the wall, and the other that is integral to the speaker.
•Easily mounts like a picture frame – After mounting
the V-Lock bracket to the wall, position the speaker so that the “V” rails on the back slide into the “V” channel of the wall mount. The process is akin to installing a picture frame onto the wall. The speaker is now fully supported by the mounting hardware, so that a balancing act is no longer necessary.
•One-step positioning and locking – Both hands are now free to orient the speaker as desired. Then, using the included tool, fully secure the speaker to the mounting hardware by tightening the V-Lock mount through the slot on the front grille. The subtle, low profile Extron badge covers the slot after installation, hiding it from view.
•Wide positioning arc – V-Lock offers wide 60° horizontal and 55° vertical travel, so that the speaker can be easily positioned to achieve optimized sound coverage.
•Theft-deterrent design – The V-Lock mounting hardware is integral to the speaker, making simple detachment impossible. Access to the hardware is possible only through the front baffle slot, which is concealed. Additionally, only the included tool will work with the hardware. Therefore, V-Lock provides an effective solution for deterring theft.
