Bose 301 Series III Owner's guide - Page 2

Your new 301 Series Ill Direct/Reflecting speaker system Thank you for purchasing this advanced new speaker system from Bose'. A number of advanced technologies, developed through years of ongoing research at Bose, and quality construction ensure you years of listening pleasure. The installation and operating principles of your 301 Series Ill system are significantly different from those of conventional speaker fr tems. This guide contains useful informa- ill iosn that will help you obtain the fullest understanding and enjoyment of your new speakers. The shipping carton contains two 301 speakers labeled Part 1, for the left speaker, and Part 2. for the right speaker. Unpack each speaker carefully, saving the carton and all packaging materials for possible later use. II either speaker appears to be damaged when unpacking, do not operate the damaged unit. Repack both speakers in their original carton and notify your authorized Bose dealer immediately. in Choices for speaker placement I Your 301 system is designed for use in a wide variety of sound environments and placement positions. The basic guidelines below are intended to simplify your choices. For lifelike sound 301 speakers provide the best performance when space around the cabinets allows the music to flow freely, reflecting off nearby walls to create a wide, transparent stereo image. See Figure 1 on page 3. Hard materials - wood, brick, glass, sheet rock, or paneling - generally provide the most effective sound-reflection. Upholstered furnishings and heavy drapes are more sound absorbent. Place the left and right speakers on the left and right sides of the room, respectively, spacing them 4 to 12 feet (1.2 to 3.6 m) apart. Vertical placement so the tweeters lace directly up or down, is not recommended. Position the speakers at least 12 inches (30 cm) away from side walls. For bass response The most accurate bass response results when the speakers are set less than 18 inches (45 cm) away from the wall behind them, and more than 18 inches from the floor or ceiling. Avoid placing the speakers exactly halfway between the floor and ceiling. If your music system seems to be lacking in deep bass, try moving the speakers closer to the wall behind them and/or nearer to the corners of the listening room. Heavy, "booming" bass can be tamed by moving the speakers away from corners and walls. 1
