Abstract
A speaker system for reproducing audio signals of multiple frequency ranges is provided. The speaker system includes a Venturi tube-shaped woofer chamber, a woofer driver, a tweeter unit, and a tweeter driver. The woofer driver and the tweeter driver reproduce low frequency audio signals and high frequency audio signals respectively. The Venturi tube-shaped woofer chamber produces a Venturi effect, offers low airflow resistance, and reproduces low frequency signals with high fidelity. An embodiment of the speaker system includes a subwoofer driver and a mid-woofer driver for reproducing extra low frequency audio signals, and medium frequency audio signals and low frequency audio signals respectively, in addition to the tweeter driver. The speaker system does not require a baffle installation. The woofer driver and the tweeter driver, and in an embodiment, the mid-woofer driver create a point sound source effect for offering a sense of immediacy to music enthusiasts and movie viewers.
