Round models feature 15º Offset Drive Unit for more midrange clarity and directionality (and an Off-Axis Targeting Switch that flattens frequency response when the primary listening position is not in line with the offset!), perfectly suits the needs of high end home theater installations.

Make sure the material into which you plan to mount the speakers (plaster, drywall, paneling, stone, etc. ) can support the weight of the speakers (see specification page for the weight of your model). ⷠMake sure the locations you select do not conceal studs, electrical wiring or plumbing. Prior to installation, hold the speaker in your chosen location to make sure it safely clears obstacles such as studs, corners, beams, lighting fixtures and door/window frames. Your cutout must be at least 1" (25mm) from adjoining walls or ceiling, internal studs or plumbing. ⷠUsing the template, trace the installation location with a pencil. You can do this by holding the template in your preferred location and tracing around it. Use a level to make certain the template is straight and plumb.
