Selecting the locations for your Lifestyle® 40 music system

When you place your speakers according to the guidelines below, a combination of reflected and direct sound provides a lifelike stereo image virtually everywhere in the room. You may experiment with the placement and orientation of the Jewel Cube® speakers and Acousti- mass® module to produce the sound most pleasing to you.

For more discussion of speaker placement and room acoustics, see “Fine-tuning your system” on page 28.

Jewel Cube speakers

Follow these guidelines to select locations that provide the maximum stereo effect from your

Lifestyle® 40 music system (Figure 2).

1.For the most lifelike sound, place the Jewel Cube speakers 6-12 feet (1.8-3.6 m) apart. They can be as close as 3 feet (1 m) or as far apart as 15 feet (4.6 m).

2.Place the Jewel Cube speakers 6-12 inches (15-30 cm) from the surface behind them.

3.Direct one cube of each speaker toward the center of the room. Direct the other cube toward a side wall to create reflected sound.

CAUTION: Choose a stable and level surface for your Jewel Cube speakers. Vibration can cause the speakers to move, particularly on very smooth surfaces. For stability, peel off the backing from the two identical rubber feet and center them in the matching shapes on the bottom of each speaker.

Note: The Jewel Cube speakers are magnetically shielded so you can place them close to the TV without af fecting picture quality.

Note: If you put the speakers in a bookcase unit, be sure to place each one at the front edge of the shelf. Placing speakers in an enclosed space can change the tonal quality of the sound. This effect is minimized if the shelves are filled with books.

The Bose 40 is an exceptional headphone model that offers an immersive audio experience, catering to audiophiles and casual listeners alike. Known for its remarkable sound quality, the Bose 40 incorporates advanced engineering and innovative technologies to deliver rich, balanced audio.

One of its standout features is the Active Noise Cancelling (ANC) technology. This system uses microphones inside and outside the ear cups to detect ambient noise, effectively cancelling it out for a serene listening environment. Whether you are commuting, traveling, or simply enjoying music at home, the ANC capability ensures you remain undisturbed by outside distractions.

The Bose 40 headphones also feature a proprietary TriPort Acoustic headphone structure, which enhances low-frequency performance without compromising mids or highs. This design ensures that users enjoy a full spectrum of sound, making every listening session a pleasure. The combination of dynamic drivers and a precise acoustic port embedded within the ear cups results in a sound that is both powerful and precise.

Comfort is a critical aspect of the Bose 40 design. The ear cups are crafted from soft materials that provide a snug fit, allowing for extended listening without discomfort. Additionally, the headband is carefully designed with cushioning, making these headphones suitable for prolonged use whether for work or leisure.

With Bluetooth connectivity, the Bose 40 headphones support seamless pairing with a wide array of devices, from smartphones to tablets and laptops. The headphone comes equipped with voice assistant integration, allowing quick access to Siri, Google Assistant, or Alexa. Users also appreciate the intuitive touch controls located on the ear cups, making it easy to play, pause, or skip tracks without needing to retrieve devices.

Battery life is another crucial feature, with the Bose 40 offering up to 20 hours of playback on a single charge. Rapid charging capabilities ensure that users can enjoy up to 3.5 hours of playtime with just a 15-minute charge, making it an excellent companion for on-the-go lifestyles.

In terms of build quality, the Bose 40 is sturdy yet lightweight, making it easy to carry around. The foldable design is perfect for travel, fitting neatly into protective carrying cases.

All these features come together to make the Bose 40 a leading choice in the headphone market, appealing to listeners who seek top-tier audio quality combined with comfort, modern technology, and longevity.
