Lansing (who would later found Altec Lansing in 1941 and JBL in 1946) to develop a new speaker system that used a two-way enclosure with a W-shaped bass horn that could go as low as 40 Hz. In 1933, the head of MGM's sound department, Douglas Shearer, worked with John Hilliard and James B.

The early Western Electric experiments added a set of 18" drivers for the low end in a large, open-backed baffle (extending the range down to 50 Hz) and a high-frequency unit, but MGM was not pleased with the sound of the three-way system, as they had concerns about the delay between the different drivers. When sound was developed for motion pictures, the basic RCA sound system was a single 8" speaker mounted in straight horn, an approach which was deemed unsatisfactory by Hollywood decisionmakers, who hired Western Electric engineers to develop a better speaker system. 1920s to 1950s precursors įrom about 1900 to the 1950s, the "lowest frequency in practical use" in recordings, broadcasting and music playback was 100 Hz.

By the 2000s, subwoofers became almost universal in sound reinforcement systems in nightclubs and concert venues. During the 1990s, subwoofers also became increasingly popular in home stereo systems, custom car audio installations, and in PA systems. As well, during the 1990s, DVDs were increasingly recorded with " surround sound" processes that included a low-frequency effects (LFE) channel, which could be heard using the subwoofer in home theater systems. With the advent of the compact cassette and the compact disc in the 1980s, the reproduction of deep and loud bass was no longer limited by the ability of a phonograph record stylus to track a groove, and producers could add more low-frequency content to recordings. Subwoofers came into greater popular consciousness in the 1970s with the introduction of Sensurround in movies such as Earthquake, which produced loud low-frequency sounds through large subwoofers. The first home audio subwoofers were developed in the 1960s to add bass response to home stereo systems. Active subwoofers include a built-in amplifier. Passive subwoofers have a subwoofer driver and enclosure and they are powered by an external amplifier. Subwoofer enclosures come in a variety of designs, including bass reflex (with a port or vent), using a subwoofer and one or more passive radiator speakers in the enclosure, acoustic suspension (sealed enclosure), infinite baffle, horn-loaded, tapped horn, transmission line, bandpass or isobaric designs, representing unique trade-offs with respect to efficiency, low-frequency range, cabinet size and cost. Subwoofers are made up of one or more woofers mounted in a loudspeaker enclosure-often made of wood-capable of withstanding air pressure while resisting deformation. While the term "subwoofer" technically only refers to the speaker driver, in common parlance, the term often refers to a subwoofer driver mounted in a speaker enclosure (cabinet), often with a built-in amplifier. Subwoofers are never used alone, as they are intended to augment the low-frequency range of loudspeakers that cover the higher frequency bands.

The typical frequency range for a subwoofer is about 20–200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-certified systems. A driver is commonly installed in an enclosure (often a wooden cabinet) to prevent the sound waves coming off the back of the driver diaphragm from canceling out the sound waves being generated from the front of the subwoofer.Ī subwoofer (or sub) is a loudspeaker designed to reproduce low-pitched audio frequencies known as bass and sub-bass, lower in frequency than those which can be (optimally) generated by a woofer. 12-inch (30 cm) subwoofer driver (loudspeaker).
