A speaker system specifically engineered for stereo reproduction to provide a balanced stereo sound throughout the room. The woofer unit is positioned off-centre on the front baffle so that within the large baffle area a substantial reflection effect can be achieved and the radiation power can be sufficiently increased to project sound over a wide area of the listening room. This baffle area is computer-tuned to enhance the 500 Hz to 1 kHz band, where directivity begins to degrade. Two tweeter units are fixed at different angles in front of the woofer, and the inward-facing one is connected in phase with the woofer. The synergistic effect of the radiation power spreads sound widely in the listening room. The other external tweeter is connected to control the acoustic energy. In the 1 kHz to 5 kHz band it operates out of phase with the woofer. When the frequency exceeds 5 kHz, the output is attenuated by a bypass circuit. The enclosure features a dual-chamber structure that divides the interior into two compartments. Inside the enclosure a sub-port system is provided, and the airflow passing through is controlled by the air resistance within the main port on the front baffle. This effectively reduces the cone excursion of the woofer while eliminating the generation of standing waves, and efficiently shifts the air inside the enclosure to a lower range. To produce reference-quality speakers, we control the design and production process with our own computer (Syncom III), developed for speaker manufacturing. At the end of the design phase, Bose listening test staff, including artists and studio engineers, check the sound by ear and provide feedback on the product.
