Bose Corporation (pronounced /boʊz/) is a privately-held, American company, based in Framingham, Massachusetts, that specializes in audio equipment.[2][3] Bose products can be found in Olympics stadiums,[4] The Broadway Theatre, the Sistine Chapel and the Space Shuttle.[4][5] Bose operates 5 plants, 151 retail stores (as of October 20, 2006) and an automotive subsidiary at Stow, Massachusetts.
In 2006 Bose ranked second in Home Audio retail, behind Sony (based on retail point-of-sale data for the period of January through October, 2006).
Background
Bose Corporation develops and manufactures audio equipment (including speakers, amplifiers, headphones, automotive sound systems [7] for luxury cars [8][9]), automotive suspension systems, and performs some general research (such as debunking cold fusion [10][11][12]). The company was founded in 1964 by Amar G. Bose, a professor of electrical engineering (who retired in 2005) at the Massachusetts Institute of Technology. As of 2005, the company employs about 12,000 people worldwide (2,000 in Massachusetts) and had revenues of over US$2.8 billion in FY 2008 (ended March 31). Bose has contracts with the US military (Navy, Air Force & Army) and NASA . Amar Bose is still the Chairman and primary stockholder, and also holds the title of Technical Director.
The company dedicates a 6,500 square meter (70,000 square feet) building in Framingham for research, development, and engineering (RD&E) purposes with a minimum annual RD&E budget of $100 million. [18] In 2004, Bose purchased an additional site from HP in Stow, Massachusetts, to house growing automotive and marketing divisions.[19]
Early years
In 1956, while a graduate student at MIT, Amar Bose purchased a high-end stereo system and was disappointed when it failed to meet his expectations. [20] He later began extensive research aimed at fixing what he saw as fundamental weaknesses plaguing high-end audio systems. The principal weakness, in Bose's view, was that the overall design of the electronics and speaker failed to account for psychoacoustics, i.e. the listener is part of the system. Eight years later, he started the company, charging it with a mission to achieve Better Sound Through Research (which is also the company's slogan).
Research history
During the company's first year in business Bose Corporation engaged in sponsored research. Its first loudspeaker product, the model 2201, dispersed 22 small mid-range speakers over an eighth of a sphere. It was designed to fit in the corner of a room, reflecting the speaker's sound as a mirror would for light in a corner cube and giving rise to an acoustical image of a sphere in a vastly larger room. Amar Bose used an electronic equalizer to adjust the acoustical output for flat total radiated power.
Although these speaker systems accurately emulated the characteristics of an ideal spherical membrane, the results of listening tests were disappointing (some of the reasons for this are detailed in a later publication[21] from Bose's research department). This led Bose to conduct further research into psychoacoustics that eventually clarified the importance of a dominance of reflected sound arriving at the head of the listener, a listening condition that is characteristic of live performances. This finding led to a revised speaker design in which eight of nine identical small mid-range drivers (with electronic equalization) were aimed at the wall behind the speaker while one driver was aimed forward, thus ensuring a dominance of reflected over direct sound in home listening spaces, replicating the dominant reflected sound fields listeners experience in live performances.
Before hearing his new design for the first time, although confident that his new design would produce a more faithful replication of the "live" listening experience, Amar Bose was unsure as to whether his new "direct/reflected" design would be a small audible improvement or a large one over his earlier design and the best commercially available loudspeakers. The new pentagonal design, named the Model 901, was a very unconventional design for speakers at the time (which were generally either full-size floorstanding units or bookshelf type speakers accompanied by a subwoofer that handled only the very lowest frequencies). The Model 901 premiered in 1968 and was an immediate commercial success, and the Bose Corporation grew rapidly during the 1970s.
Amar Bose believes that imperfect knowledge of psychoacoustics limits the ability to adequately characterize quantitatively any two arbitrary sounds that are perceived differently, and to adequately characterize and quantify all aspects of perceived quality. He believes, for example, that distortion is much over-rated as a factor in perceived quality in the complex sounds that comprise music, noting that a sine wave and a square wave (a hugely distorted sine wave) are audibly indistinguishable above 7 kHz. Similarly, he does not find measurable relevance to perceived quality in other easily measured parameters of loudspeakers and electronics, and therefore does not publish those specifications for Bose products. The ultimate test, Bose insists, is the listener's perception of audible quality (or lack of it) and his or her own preferences.Unlike other major speaker manufacturers, Bose does not publish specifications relating to the measured electrical and objective acoustic performance of its products. This reluctance to publish information is due to Bose's rejection of these measurements in favour of "more meaningful measurement and evaluation procedures"[25].
Additionally, the company researches portable audio within the fields of Circumaural and Supra-aural headphones, centering within the lines of Acoustic Noise Cancellation (see Bose Headphone Family).
Cold Fusion Research
In 1991 Bose Corporation began research into cold fusion [26][27]. Company engineers built a precision calorimeter[28], began replicating prior experiments, and concluded that there was no net energy gain.
Bose Stores
Bose retail store in Century City
In 1993 Bose opened up its first store in Kittery, Maine. Since then Bose has opened 160 stores in the United States and numerous locations world-wide. In Britain there are 8 Bose stores, including one on Regent Street. Bose stores feature a 15 to 25 seat theater which has a short film that demonstrates a Lifestyle Home Entertainment System using a high-definition front LCD projector. At one point in the show a three-sided box is placed in front of the center speaker, and the Lifestyle system automatically adjusts and corrects the sound in the room via AdaptIQ technology. Stores located in factory outlets discount prices on some products and sell both new and factory renewed (retested open-box) products.
Lines of Specialized Products
Car Audio
Bose Car Audio
Bose has a wide range of speakers for car audio and has even started to make consoles for car audio including the Bose Media System which can play CDs, DVD audio discs, DVD video discs, Super Audio CDs, MP3s, AAC, and features a music storage system. Different Bose audio systems are available as a standard or an option (depending of the vehicle level) in vehicles with most GM labels (including Buick, Cadillac, Chevrolet, GMC, Hummer and SAAB), as well as in same European models from Alfa Romeo, Audi, Ferrari, Lancia, Maserati, Maybach, Mercedes-Benz and Porsche, and also in a some Japanese-production cars. Because of integration with a vehicle and adjustment for its acoustic parameters, Bose audio is not available aftermarket.
At the 2007 auto show in Geneva, Switzerland Bose launched a new media system with the Ferrari 612 Scaglietti. The new system combines stereo, navigation, and hands free calling into one component and interface.[29] In 2007 the Bose media system won the International Telematics Award for the "Best Storage Solution for In-Car Environment" .
Automotive Suspension System
Another area of research and development at Bose Corporation is two-state, non-linear power processing and conditioning. Several early patents were awarded to Amar Bose and other Bose engineers and this technology is one of the key elements in an innovative project that the company disclosed in 2004 after more than 20 years of research,[30] an automobile suspension system that uses electromagnetic principles instead of the hydraulics that are common today. This system uses electromagnetic linear motors to raise or lower the wheels of an automobile in response to un-even bumps or potholes on the road. The wheels are raised when approaching a bump, or extended into a pothole, within milliseconds, thus keeping the vehicle steady. This technology is another application of Bose's active noise reduction technology for speakers and earphones. The unevenness of the road is sensed, and processed much like a sound wave. A cancelling wave is generated, which is applied to the wheels through the linear motors.[17] Amar Bose expects the system to be available commercially on high-end luxury cars by 2009.[32] In a French interview Bose even shows off the car jumping over an obstacle.[33] Bose says that the system is "high cost" and heavy, even after nearly three decades, and $100 million, of development[34].
Pro Speaker Systems
Bose produces professional speaker systems like the 102, 402, 802, 25SE, 32SE, 32, 8, 16, 3, and 6 that are made for musicians, professional and commercial applications.
L1 Personalized Amplification System
Bose makes the L1 Personalized Amplification Systems for Musicians[35]. Bose has been actively encouraging the use of the term L1 for this product line, and frequently refers to it on their website[36] as the L1 portable line array.
On October 15, 2003, Bose Corporation began selling the L1 Model I family of products through its internal sales division and www.bose.com (in the U.S., Puerto Rico, Canada or U.S. Virgin Islands only). Guitar Center and Musicians Friend began selling these products on November 1, 2003, in stores nationwide.[37]
On March 28, 2007, Bose Corporation introduced the L1 Model II system. It became available for sale May 1, 2007, through its internal sales groups and participating authorized dealers.At the same time the T1 ToneMatch Audio Engine was introduced. This separate processor is the main input and user interface for the Model II. It is also compatible with the original L1 System. That original L1 System is now known simply as the L1 Classic.[41] It was replaced by the L1 Model I. This new model looks and is functionally similar to the Classic. The L1 Model I is RoHS compliant, as is the L1 Model II.
Bose maintains an active Musicians Community Message Board for support, and there is an owner maintained Unofficial Wiki and FAQ
Bose-Electroforce
In 2004 Bose acquired company assets related to the development, manufacture and sales of materials testing equipment, founding the ElectroForce Systems Group The ElectroForce Systems Group provides materials testing and durability simulation instruments to research institutions, universities, medical device companies and engineering organizations worldwide.
