The SHS-LF comprises 4 low frequency drivers inside a concealed enclosure providing optimal deep bass performance. The discrete sub-woofer will amaze listeners. A 70V/100V transformer is included with primary taps at 1.9, 3.8, 7.5, 15, 30, and 60 watts (@70.7V) to match and balance the subwoofer with full range speakers without the need for separate amplification. The tap selector switch also includes a trans-former bypass setting for 8Ω / direct coupled applications. The SHS-LF is also an installer’s dream with its integrated rail system. All the parts are built into the enclosure including the tile rails, with no rail screws required for installation. Once the 4 rails are pulled out from the enclosure it is ready for installation. An installer only needs to drill a 2.75" hole into the ceiling tile, set the product through the hole, and screw on the adaptive dispersion lens. The SHS-LF ships with the ability to utilize the Adaptive Dispersion Lens in two different configurations for various applications. Installations with ceilings between 10' and 14' should use the 8mm dispersion lens with the solid lens cover attached. Installations with ceiling heights above 14' or in applications that require maximum output, the direct fire lens should be used with the perforated panel attached. The concealed design is achieved using a patented 3" diameter dispersion lens with a micro trim ring. Once installed, the visual appearance is minimized to the size of a high-end ceiling sprinkler head. The SHS can become a true chameleon through AtlasIED’s DesignLab. AtlasIED offers custom color matching via UV printer that enables an integrator to submit an image or sample of the ceiling, then, using a state-of-the-art print service, a custom lens and trim ring that matches the submitted sample will be shipped to the customer.
