QSC Subwoofer

After more than three decades in the business, QSC Audio Products, Inc., has become a globally recognized leader in audio manufacturing. This prominence is the result of the company's mission to establish new standards of reliability and performance through the development of breakthrough technologies. QSC changed the face of amplifier technology with the introduction of QSC's exclusive PowerWave switching power supply, a technological advance that makes heavy, bulky and inefficient amplifiers a thing of the past. PowerWave, first incorporated into the revolutionary PowerLight Series and now used in three other amplifier lines, is proof that high power can be achieved in small, lightweight packages. While QSC continues to set the standard for amplifier technology, the company has also made significant strides in computer control, digital signal processing and signal transport. QSControl (pronounced Q's Control), a remote audio monitoring system application, has proven its performance in systems worldwide, from the world's tallest buildings (the Petronas Towers in Malaysia) to Mandalay Bay Hotel and Casino in Las Vegas. QSC recently entered the professional loudspeaker business. Several of the company's enclosures incorporate Composilite™, a patented core composite technology that yields superior acoustic properties, lighter weight, and outstanding weather resistance compared to conventional enclosure materials. The introduction of RAVE (Routing Audio Via Ethernet), which gives users a simpler way of transporting up to 64 channels of digital audio using Peak Audio's CobraNet technology, provides more evidence of QSC's commitment to creating system solutions based on open standards and protocols. "When this company was started, there was a common commitment to creating with integrity," said QSC CEO Barry Andrews. "That commitment has strengthened over the years. QSC products have a reputation for quality, innovation and reliability. Moving into the fully integrated systems allows us to expand that commitment into an area we feel is the future of system design." The exceptionally high value of QSC products is achieved through developing leading technologies, world-class manufacturing techniques, and the purchasing power possible as the world's leading amplifier producer. To meet growing customer demand, QSC has expanded its manufacturing capability with a new 81,000-sq.-ft., state-of-the-art production facility. The new factory, which has the ability to triple QSC's production capacity, is located next to QSC's current 51,000-sq.-ft. headquarters in Costa Mesa, Calif. Manufacturing, warehousing, corporate offices, engineering, technical services, and sales are housed in both buildings.

Subwoofer

Subwoofers are speakers that are designed to reproduce low-pitched or the bass frequencies typically ranging from about 20 to 200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-approved systems. These are complete loudspeakers intended to enhance the low frequency range of loudspeakers covering higher frequency bands. Subs, another term for subwoofers, are made up of one or more woofers in a loudspeaker enclosure capable of withstanding air pressure while resisting deformation. These subs require more power to operate because they are bigger (usually between 20.3 cm and 38.1 cm in diameter). Enclosures are available in a variety of designs that differ by efficiency, bandwidth, size and cost. Designs include bass reflex with a port or passive radiator in the enclosure, infinite baffle, horn-loaded, and band pass designs. A multimedia home theater system in low-cost compact plastic cabinet that is said to be a subwoofer is more appropriately called a bass driver because it is too small to produce deep bass. Subwoofers are also powered by amplifiers. Active or powered subwoofers are driven by a built-in amplifier. Passive subwoofers have an external amplifier, subwoofer drivers and enclosures. Subwoofers are popular because of they can pack a large, low frequency punch in a small space, providing a powerful audio experience like being in a movie theater or a concert venue. They are installed in cars or at home as part of a home theater system which is a more common application. In both cases, the subwoofer or low frequency speaker is not considered a stand alone device but helps to reinforce the higher pitched sound produced from the speakers.
