iC1, iC2, iC3 and iC4 In-Ceiling Loudspeakers OWNER’S MANUAL Now Hear This 527 Stone Road Benicia, CA 94510 800-NHT-9993
Thank you for your purchase of the NHT in-ceiling loudspeaker. Please take a few minutes to read through this owner's manual prior to installing your new speakers. The information provided will help you to obtain maximum performance from your audio system.
Caution: The NHT in-ceiling speakers should be installed by an experienced and licensed custom installation professional. Be sure that the installer possesses sufficient skill, the proper tools, knowledge of local fire and building codes, and a familiarity with the structure of the building (especially wall and/or ceiling materials, layouts, electrical and plumbing lines, etc.). Placement NHT in-ceiling speakers are designed for installation between standard wood joists.

4. During the drywall phase, cut a hole around the bracket so fig.3 that the drywall surrounds the protruding lip of the mounting bracket (iCB6 = 8 13/16” Dia., iCB8 = 10 1/4” Dia.). Once installed, the lip of the speaker assembly will extend about 1/2 inch beyond the perimeter of the cutout to hide minor imper- Drywall fections in the cutout (fig.3). 5.
Installation: Existing Construction (retrofitting finished ceilings) Warning: Exercise caution when drilling into existing ceilings. Do not drill through electrical wires, pipes, conduits, heating or air conditioning ducts. If you feel resistance while drilling, stop immediately. Do not install the speaker into a drop ceiling or soft ceiling, as this type of construction will not support its weight. fig.6 1.
Tech Tips: Optimizing Sonic Performance Bass response is smoothest when the speaker is mounted into a rigid ceiling that flexes very little. For improved performance, add cross-braces horizontally roughly one and a half feet to either side of the speaker location. Use wood glue and extra screws when attaching the drywall to the joists around the speaker. Additionally, once the speaker cutout has been made in the drywall, add a strip of wood glue where the drywall meets the joists and cross-braces.
Operation The NHT in-ceiling speakers are designed to handle a wide range of listening levels, but every speaker has limits. It is important to use common sense and listen for signs of possible distress from the speakers. Underpowered amplifiers are most often the cause of speaker damage. For example, a 60-watt amplifier runs out of power when called upon to produce more than 60 watts, and the resulting distortion can damage the speaker.
