2. Unscrew the male banana connec-

tors from the bottom of the speak- er and replace them with the sup- plied Speaker Terminal Screws (see Figure 8A).

3. Run speaker wires through the ceiling, from the speaker mount-

ing location to the amplifier.

• Consult local building codes before running speaker wires through ceilings.

4. Strip ½” – ¾” of insulation from each speaker lead. Twist the wire strands to ensure that there are no stray strands. (Stray strands that touch each other can cause a

short-circuit that can damage the amplifier.)

5.Wrap the bare wire ends around the Speaker Terminal Screws and tighten the screws to secure the wires. Be sure to connect amplifier “+” to speaker “+” and amplifier “–” to speaker “–”. (See Figure 8B.)

IMPORTANT: 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 amplifier.)

6.Feed any excess speaker wire back through the ceiling and place the speaker in the desired mounting location.

7.Mark the locations of the four mounting holes on the ceiling.

8.Drill holes at the marked locations and install drywall anchors into the holes.

9.Place the speaker at the mounting location again and drive four 1½”-long drywall screws through the four mounting holes on the speaker and into the drywall anchors (see Figure 9).

IMPORTANT: Always use low-torque settings; NEVER over-tighten.

10. Replace the grilles on the speakers.

Speaker Adjustments

Rotating the Speaker

When installed using the Mounting Plate, the SM55 and SM55SST can be rotated around their center axes after installation to align them with architectural or design elements in the room. (See Figure 10.)

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.
