Bose home audio products

Home audio products sold by Bose Corporation are listed below.
2.1 channel amplifiers
From 1990 until the early 2010s, Bose sold several 2.1 channel audio systems, which used two small satellite speakers and a subwoofer. Early systems used an in-built CD player, followed by a DVD player and later models were AV receivers (which used external audio sources).
CD players
The first 2.1 audio system from Bose was the "Lifestyle 10", which was released in 1990. The Lifestyle 10 included a single-disk CD player, an AM/FM radio and "Zone 2" RCA outputs which could be configured to output a different source to the primary speakers.
A 6-disk magazine-style CD changer was introduced in 1996 and a touchscreen remote was introduced in 1999.
DVD players
The first 2.1 audio system from Bose to include a DVD player was the "3-2-1", released in 2001. The "3-2-1 GS" model was introduced in 2003, named for its use of Bose "Gemstones" small speakers (which have two drivers pointing forward and one pointing to the side).
The 3-2-1 was replaced by the "321 Series II" in 2004, which included two small speakers and a subwoofer. The 321 Series II was praised for its performance for movies, but was criticised for its performance with music and for lacking a HDMI connection. The 321 Series II GS had similar outcomes, however it was also criticised for value for money.
An internal hard drive for storing music (in mp3 and wma formats) was introduced in 2005 for the "321 GSX" model.
The "321 Series III" replaced the Series II in 2008, adding an HDMI output connection. A "GSXL" model was introduced with a larger hard drive advertised as having a capacity of 200 hours of music (however the bitrate used is not known).
AV receivers
The first 2.1 AV receiver system from Bose was the "Freestyle", which was introduced in 2002 and used S/PDIF and RCA inputs. The system used the same speakers as the 3-2-1.
The Freestyle was replaced by the "CineMate" in 2005, which has only RCA connectors and uses the same speakers as the 321 Series II. A fibre optic input was added for the CineMate Series II, which was released in 2009.
The "Lifestyle 235" was released in 2010 and added an AM/FM radio, iPod dock and HDMI inputs.
5.1 channel amplifiers
From 1994 until the mid-2010s, Bose sold several 5.1 channel audio systems, which used four small satellite speakers and a subwoofer. Early systems used an in-built CD player, followed by a DVD player and later models were AV receivers (which used external audio sources).
CD players
The first 5.1 audio system from Bose was the "Lifestyle 12", which was released in 1994. The Lifestyle 10 included a single-disk CD player and an AM/FM radio. Beginning in 1996, some models were sold with a 6-disk CD changer (using a magazine, so playback needs to be stopped when changing CDs). In 1999, the "Lifestyle 12 Series II" models added a coaxial S/PDIF input.
DVD players
The first products to include a DVD player were the "Lifestyle 28" and "Lifestyle 35" models, which were released in 2001.
The Series II versions of these products, released in 2004, used a "BoseLink" audio output instead of the previous "Zone 2" RCA outputs. The Lifestyle 38 was one of 22 products to be listed in the Sound and Vision Magazine 2004 Reviewer's Choice Awards. The Lifestyle 48, along with the Boston Acoustics Avidea 610, was a winner of the Home Theatre category in the 2006 AudioVideo International "Hi-Fi Grand Prix Awards".
In 2006, the Series II models were replaced by the Series III models, however the amplifier unit itself was unchanged.
The Series IV version of the DVD-based models were introduced in 2007 and saw HDMI inputs and outputs added to some models.
AV receivers
The first 5.1 AV receiver from Bose was the 1998 "Companion" model, which used RCA, S-Video and Composite connections. The Companion was one of 100 products listed in Popular Science's 1996 "Best of What's New" article.
In 2007, the "Lifestyle V20" and "Lifestyle V30" products added HDMI and S/PDIF connections.
The "Lifestyle T10" and "Lifestyle T20" models, released in 2010, added a USB audio input. The "Lifestyle V25" and "Lifestyle V35", also released in 2010, added an iPod dock and two USB audio inputs.
Speaker packages
Mono
2201
The "2201" was released in 1966 and was Bose's first speaker system. It consisted of 22 five-inch drivers and was designed to be located in the corner of a room, using reflections off the walls and floor to disperse the sound. The system included tone controls and a switch to attenuate frequencies below 50 Hz. The 2201 was a failure in the market and was discontinued after three or four years.
Stereo
901
The "901" was released in 1968 and was a conventional design consisting of two floorstanding speakers. The system has nine drivers per channel, a separate amplifier unit, and an equalizer.
Unlike other Bose speakers, the 901 Series was not intended to be used without their included 901 Active Equalizer. While the speakers included metal pedestal stands, ceiling mounts were also available.
It was sold until 2016, when the 901 Series VI was discontinued.
A review of the 901 by Stereophile magazine in 1979 concluded:
If we were to judge the 901 in terms of the best sound available, then, we would say that it produces a more realistic semblance of natural ambience than any other speaker system, but we would characterize it as unexceptional in all other respects. It is ideal for rock enthusiasts to whom sheer sonic impact is of paramount importance, and for classical listeners who want the next best thing to ambient stereo without the cost and the bother of rear-channel add-ons. However, we doubt that the 901 will appeal to perfectionists who have developed a taste for subtleties of detail and timbre.
In the 1990s, Bose manufactured a "Lifestyle 901" system that integrated two 901 speakers, the 901 Active Equalizer, and a Lifestyle stereo receiver that integrated an A/M-F/M radio tuner and a CD player, as well as a remote control.

The "301" bookshelf speakers were released in 1975.Impedance 8 OHMS

The Bose 301 Series II is a classic and powerful direct/reflecting speaker system delivering ultra-clear sound with stereo effects of remarkable quality. Direct/Reflecting speaker technology in these Bose stereo speakers lets you experience a live music concert in the comfort of your home. Asymmetrical design of the Bose 301 Series II offers balanced sound effects throughout the room. Integrated 8-inch woofer in this direct/reflecting speaker system provides rich and powerful bass effects. High-sensitivity tweeters of these Bose stereo speakers facilitate wide scattering of the sound, letting you feel the surround effects even if you are at a distance. Dual frequency crossover network in the Bose 301 Series II offers outstanding sound clarity by optimizing output frequencies. The most recent version, the "301 Series V" has been on sale since 2002.
201
The "201" bookshelf speakers were released in 1982. Similar in design to the larger 301 Series, the 201 Series featured smaller drivers (speakers). The most recent version, the "201 Series V" has been on sale since 2015.
Acoustimass

The "Acoustimass 5" was released in 1987 and consists of a bass module and two "double cube" satellite speakers. This was followed by an "Acoustimass 3" system in 1989, which consisted of two "single cube" satellite speakers and a smaller bass module.
, the Acoustimass 5 currently remains on sale, in the form of the Series V version. The Acoustimass 3 was discontinued in 2016.
The original Acoustimass bass module featured a wooden ported enclosure round port (which later changed to a new cabinet design with a round port) while the current Acoustimass module features a larger, square port (the Acoustimass 3 and 5 systems still use the older-style Acoustimass module). The cube speakers (called "Jewel Cubes") were recently redesigned with a slimmer profile, and are no longer adjustable. New mounting brackets allow the newly-designed speakers to mount nearly flush to the wall.
In the past, Bose has manufactured a 7.1-channel Acoustimass system, the Acoustimass 16, which featured five "double cube" satellite speakers, a single center-channel speaker, and an Acoustimass bass module.
Surround sound
The company's first surround sound speakers were the "Acoustimass 6" and "Acoustimass 10", both released in 1996. Both products were 5.1 systems, with the Acoustimass 6 using "single cube" satellite speakers and the Acoustimass 10 using "double cube" satellite speakers.
The "Acoustimass 15" 5.1 system was sold from 1998 until 2006, and the "Acoustimass 16" 6.1 system was sold from 2002 until 2006.
Other Stereo Speakers
Bose has manufactured several other stereo speakers.
Environmental Series
First introduced in 1994, the 111 Series Environmental speaker was an indoor/outdoor version of the Model 101 Music Monitor, which was introduced in the late 1980s. The 111 was replaced by the 151, which featured a similar design, but a revised metal speaker grille.
In 2004, the 151 was replaced by the 151 SE, which now featured "Direct/Reflecting" speaker technology for wider coverage, as well as the versatility of vertical or horizontal mounting using the included flushmount brackets.
Also introduced in 2004, the 251 Series Environmental Speaker was a larger version of the 151 Series.
The 131 Marine Speaker was a flushmount speaker that was meant to be installed on a boat, and could be connected to the boat's receiver.
The Freespace 51 is an "in-ground" landscape speaker that features omnidirectional, 360-degree sound projection, as well as a bass port. The speakers are designed to blend in with outdoor landscaping, and the wiring features "Posi-Tap" connectors, so that speaker wiring can be hidden underground.
"Virtually Invisible" Series
In the early 2000s, Bose introduced the 191 Virtually Invisible in-ceiling/in-wall loudspeakers. These speakers included both round and rectangular speaker grilles that could be installed according to the homeowner's preferences.
The 191 has since been replaced by the "x91 Series" Virtually Invisible in-ceiling/in-wall loudspeakers (which include the 591, 691, 791, and 891 loudspeakers). Unlike the 191, which included two different styles of speaker grilles, the x91 Series included different models made specifically for in-wall or in-ceiling installation.
The speaker grilles can easily be painted to match the homeowner's decor, and the 191 Series could also included in a line of "installed" surround-sound systems in new home construction.
