SD-20

The Look
Harmony has easily accessible connecting gold-plated binding posts terminals. The entire unit lies on a steel frame panel painted with strong oven-enameled paint. The panel forms the loudspeaker frame. Steel hinges grip and hold the spherical loudspeaker to the panel frame.

The panel frame has elongated, rectangular steel hinges that fasten the loudspeaker to the wall. While these hinges are very strong, installers can also easily remove the entire unit from the wall if necessary*. The covering of the loudspeaker is a perforated metal grill for optimum acoustic transparency.

The Sound
Harmony's panel has an opening at its center. Engineered according to an "eyeball" configuration, the loudspeaker enclosure can be swiveled in all directions, enabling tilting the loudspeaker in the preferred direction to maximize acoustic performance.
