SONANCE SM55 & SM55SST SURFACE-MOUNT SPEAKER

The Mounting Plate allows the speaker to be installed after the ceiling has been finished. The Mounting Plate also allows the speaker to be rotated after installation to align it with design elements in room.

3.If there is no J-box in the ceiling, the speaker can be mounted directly on the ceiling surface, without using the Mounting Plate.

If the speaker is installed without the Mounting Plate it cannot be rotated after installation.

Installation Using a J-Box

1.Run speaker wires through the ceiling or conduit, from the amplifier into the J-Box. Mark the wire’s “+” and “–” leads.

Consult local building codes before running speaker wires through ceilings.

2.Bring the speaker wires through the J-Box and attach them to the binding posts on the back of the Mounting Plate. (The SM55 plate has one set of posts; the SM55SST plate has two sets, see Figure 4.) The binding posts will accept single banana plugs or bare wire.

Loosen the set screw on the binding post, insert the plug or wire, then tighten the set screw to secure the wire.

IMPORTANT: When using bare wire, be sure that no stray “+” and “–” strands touch each other. (Stray strands that

touch each other can cause a short- circuit that can damage the ampli- fier.)

3.Use the 1½” x 6-32 flat head screws included

with the Mounting Plate to attach it to the J-Box. (See Figure 5.)

• Use two screws for a single-gang J-Box; use four screws for a double-gang J-Box.

painted after the Plate is installed. Remove the paint plug before installing the speaker.

5.To install the speaker, place the speaker against the Mounting Plate so that the male terminal connectors on the speaker fit into the female connectors on the Mounting Plate. The neodymium magnets on the speaker will secure the speaker to the Mounting Plate. (See Figure 6.)

Be sure to align the “+” and “–” connectors on the speaker with the corresponding connectors on the Mounting Plate.

After the speaker is installed you can rotate it to align it with design elements in the room. See Speaker Adjustments: Rotating the Speaker, on page 3.

Installation Without a J-Box

1.Remove the grilles from the speakers.

The grilles are held on the speakers by 2 small tabs on each side of the grille frame. Use a flat-blade screwdriver to gently pry each side of the grille frame away from the speaker to release the tabs, and slide the grille off the speaker (see Figure 7).

SM55, SM55 SST specifications

The Sonance SM55 and SM55 SST are high-performance architectural speakers designed to blend seamlessly into any environment while delivering exceptional sound quality. These models are particularly favored in both residential and commercial installations, where aesthetics and acoustics are paramount.

One of the standout features of the SM55 is its robust design, which includes a pivoting 1-inch soft-dome tweeter that allows for precise sound dispersion. This feature enables the speaker to deliver crisp and clear high frequencies, ensuring that every note in music or dialogue in film is rendered with excellence. The tweeter's pivot allows for greater flexibility in placement, making it easier to direct sound toward the listening area.

The SM55 series is equipped with a 5.5-inch polypropylene cone woofer. This woofer provides a rich and detailed mid-bass response essential for a full-bodied audio experience. The materials used in the construction of the woofer also contribute to reduced distortion, ensuring that the sound remains clean even at higher volume levels.

Additionally, the SM55 and SM55 SST incorporate Sonance's proprietary technologies aimed at optimizing performance. The speaker features a dual voice coil design that enhances its ability to handle higher power levels, making them suitable for both casual listening and more intensive audio experiences. Moreover, the SST version comes with a high-output transformer, allowing for easy integration into distributed audio systems. This transformer supports both 70V and 100V installations, making the SM55 SST ideal for commercial settings where long runs of speaker wire are necessary.

Installation of the SM55 series is made easy with a simple, low-profile design that includes a magnetic grille. The grille can be painted to match any interior decor, making it a versatile option for a variety of applications. The speaker's low-profile appearance ensures that it does not detract from the design of the room, providing a visually appealing audio solution.

In summary, the Sonance SM55 and SM55 SST speakers combine state-of-the-art technologies with user-friendly features to create an exceptional listening experience. Their rich sound profile, ease of integration, and aesthetic adaptability make them a prime choice for anyone seeking high-quality architectural speakers. Whether in a home theater or a commercial space, the SM55 series is engineered to meet and exceed the expectations of both audio enthusiasts and casual listeners alike.
