Extron Electronics is now shipping the SM 28 SpeedMount, a two-way surface-mount loudspeaker with a proprietary concealed wall mounting system.
The SM 28 includes an 8-inch (20.3 cm) woofer with dual tuned ports and a 1.1-inch (2.8 cm) tweeter. Frequency range is stated as 59 Hz to 22 kHz, with a power rating of 90 watts continuous (pink noise) and 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, while the SM 28T version can operate in 8-ohm direct as well as 70- and 100-volt modes. The SM 28T has a six-position power tap selector for up to 64 watts, which can conveniently be accessed through the grille from outside the loudspeaker.
“SpeedMount has quickly become a favorite of AV integrators, and we’re pleased to bring the fast installation capability to the larger format SM 28 speaker, which can support both low and high impedance applications,” says Casey Hall, vice president of sales and marketing for Extron.
“Our exclusive mounting system allows a large number of SM 28 speakers to be installed quickly and efficiently, so that multiple sound systems can be completed within a short installation window.”
To meet a variety of installation needs, the flexible mounting system includes a 0-degree mounting plate and a 10-degree mounting adapter. The 0-degree mounting plate provides the electrical connections and allows the SM 28 to be oriented vertically or horizontally, flush with the wall. When the 10-degree mounting adapter is added to the mounting plate, the SM 28 can be positioned with a 10-degree 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 five-year parts and labor warranty. It’s available in a black or white finish and includes the mounting plate and mounting adapter. Also available is an optional yoke mount kit that allows for vertical or horizontal mounting on a wall, or on a ceiling, and provides 180 degrees of pivot in 10-degree detented steps.
