Extron has launched the SM 28 SpeedMount Surface Mount Speaker, a two-way speaker with a patent pending, concealed wall mounting system. It features an 8″ (20.3 cm) woofer with dual tuned ports and a 1.1″ (2.8 cm) tweeter. The SM 28 provides a frequency range from 59 Hz to 22 kHz, and a power rating of 90 watts continuous pink noise, 180 watts continuous program capacity. The Extron exclusive mounting system is designed to accommodate division-of-labor installations and save costs. The SM 28 is available as an 8 ohm model, and an SM 28T version which can operate in 8 ohm direct as well as 70 volt and 100 volt modes. The SM 28T features a six-position power tap selector for up to 64 watts, which can conveniently be accessed through the grille from outside the speaker.
For installers, the flexible mounting system includes a 0° mounting plate and a 10° mounting adapter. The 0° mounting plate provides the electrical connections and allows the SM 28 to be oriented vertically or horizontally, flush with the wall. When the versatile 10° mounting adapter is added to the mounting plate, the SM 28 can be positioned with a 10° tilt downward, upward, left, or right.
The SM 28 saves time and installation costs for AV system contractors working with low-voltage contractors in a division-of-labor installation. During rough-in, a low-voltage contractor installs the mounting system on the wall and terminates the speaker cable to the mount’s integrated wiring contacts. Later, the AV system contractor completes the installation by sliding the SM 28 onto the mount.
The SM 28 is sold in pairs and carries a 5 year parts and labor warranty. It is available in a black or white finish and includes a 0° mounting plate and a 10° mounting adapter. Also available is an optional yoke mount kit for the SM 28. It allows for vertical or horizontal speaker mounting on a wall, or on a ceiling, and provides 180° of pivot in 10° detented steps.
