4.Installing CWM3 Series Speakers

To install a CWM3 Series speaker, proceed as described in the following paragraphs:

4.1  Using the supplied aperture template, mark a cut line on the wall. Check the cut line defines the correct aperture dimensions. Cut along the line with an appropriate tool to create a rectangular aperture in the wall.

Note: Ensure that there is enough free space internally adjacent to the aperture for the dog clamps.

Note: To reduce the possibility of the wall buzzing or rattling, adhesive mastic can be applied between the studs and sheetrock in the vicinity of the speaker aperture.

4.2  If speaker cable is already present in the wall, feed the cable through the aperture. If speaker cables are not already installed, this should be done at this stage. It is likely that you will need to gain access through the floor above to route the cables down through the wall space.

Leave enough spare cable through the aperture to ease connection to the speaker, but not so much that it is likely to buzz or rattle when pushed back into the wall space. Approximately 1.0m (3 ft) is appropriate.

Note: Always use high quality, low resistance speaker cable. Low resistance is especially important if the length of cable from amplifier to speaker exceeds 5m. Your local Bowers & Wilkins retailer will be able to offer advice on speaker cable selection if required.

4.3  Now connect the speaker cable to the spring terminals on the crossover board. Ensure that the speaker connection polarity is correct: the cable connected to the positive terminal on the amplifier should be connected to the red spring terminal on the speaker. Similarly, the cable connected

to the negative terminal on the amplifier should be connected to the black spring terminal on the speaker. Diagram 3 illustrates cable connection.

Note: If an amplifier is already connected to the cable it should be switched off while connections are being made to the back box.

4.4  With the speaker connected to the cable, it can be inserted into the wall aperture. Ensure that the four dog clamps are rotated inwards so that they can pass through the aperture, and then hold the speaker flange flush to the wall. Take care that the connection cable does not become trapped anywhere.

To secure the speaker use a Phillips screwdriver inserted through the dog-clamp access holes in the front of the speaker. Take great care not to damage the speaker drive units with the screwdriver. Engage the screwdriver with each dog-clamp screw in turn and tighten them. Diagram 4 illustrates inserting and securing the speaker.

Note: If the wall is to be painted after the speakers have been installed, the supplied paint mask should be used.

4.5  The grille can now be fitted. The grille is held in place magnetically so simply needs to be aligned with the groove in the frame flange where it will click into place. Diagram 5 illustrates fitting the grille.

The CWM3 Series speaker is now installed and ready for use.

CWM3 specifications

The Bowers & Wilkins CWM3 is an in-wall loudspeaker that exemplifies the company's commitment to delivering high-quality sound while integrating seamlessly into any living space. Designed for custom installation, the CWM3 offers robust performance for both music and home theater applications.

One of the main features of the CWM3 is its compact and discreet design, which allows it to blend perfectly with the wall without compromising sound quality. The flush-mount installation ensures that the speaker remains virtually invisible, making it an excellent choice for those who want a clean aesthetic in their home.

The CWM3 employs advanced technologies to deliver a remarkable audio experience. It is equipped with a 6.5-inch woven Kevlar bass driver, renowned for its ability to produce powerful low frequencies with precision and clarity. This driver is complemented by a 1-inch aluminum dome tweeter, providing a smooth and detailed high-frequency response. Together, these elements create a balanced soundstage that is engaging and immersive.

Furthermore, the CWM3 features Bowers & Wilkins' innovative FST (Fixed Suspension Transducer) technology, which enhances the mid-range frequencies and helps to create a more natural and transparent sound. This technology minimizes distortion, ensuring that vocals and instruments sound as intended, making it an ideal choice for critical listening environments.

The speaker's construction is robust, featuring a rigid enclosure design that minimizes unwanted resonance. This ensures that the sound produced is clear and free from coloration, which is crucial for achieving the high-fidelity audio that Bowers & Wilkins is known for.

Another notable characteristic of the CWM3 is its adaptability. The speaker comes with a switch that allows users to adjust the sound output based on the room's acoustics, whether it be for a larger open space or a more intimate setting. This flexibility ensures optimal performance, regardless of the installation environment.

In conclusion, the Bowers & Wilkins CWM3 is a remarkable in-wall speaker that combines aesthetic elegance with advanced audio technology. Its high-quality drivers, innovative features, and customizable performance make it an excellent choice for those looking to enhance their home audio experience without the bulk of traditional speakers. With the CWM3, Bowers & Wilkins continues to uphold its legacy of excellence in sound quality and design.
