Apogee manufactures or has manufactured the following equipment (click to expand models list):Ribbon Speakers
TAC (June 27, 2011): Not to be confused with Apogee Sound (pro audio) or Apogee Electronics (pro audio).
Jerry Reynolds (June 12, 2002): Due to a change of ownership and a federal court directive, the main ADS Technologies manufacturing plant was closed and liquidated. All remaining inventory at ADST (PPI, ADS, Wired, Apogee, etc.) was sold.
In early 2000 Australian Graeme "Graz" Keet took over spares responsibility supplying upgraded tolerance parts for existing speakers (Apogeeribbons), and also started producing Perigee ribbon speakers in addition to "classic" Apogee Acoustics remakes on demand. In 2004 a new flagship speaker "DEFINITIVE" was released, a full planar in the style of the original Apogee speakers but boasting greater performance though engineering advances and tolerances. One of the main advances was in efficiency with a claimed 100dB/w. Definitive was a speaker only really suited to the most committed of audiophiles as the price was over $100,000 per pair.
Two years later another new speaker design, also high efficiency, called Apogee Synergy 1.5 was released. The company continues manufacturing to order, smaller than the Apogee Acoustics of the past but with a good reputation for quality and accurate engineering. Spares service continues though bass repairs are only carried out directly at the factory or through various Graz trained Installer-agents worldwide, under licence from Graz to install Apogee Acoustics parts to refurbish the early Apogees. Some act as dealers for the new speakers.
1981 Apogee Acoustics was founded by Jason Bloom and Leo Spiegel, and developed and produced a line of high quality Full-Range Ribbon Loudspeakers.
1982 The Full Range also known as "The Apogee" is the first full ribbon speaker released.
1985 The legendary Scintilla is released to critical acclaim around the world.
1986 Release of the original Duetta, a smaller and more importantly easier to drive Apogee.
1989 The revised Caliper Signature is released.
1990 Apogees smallest and cheapest speaker The Stage is released, the first with etched ribbon components.
1991 Apogee introduced their first line of hybrid ribbon speakers. These speakers all carried the Centaur name, and had higher impedances and were somewhat easier to drive than the full range speakers. They were also less expensive.
1994 The Slant range, replacement range for the Centaurus are released.
1995 Apogee introduced their "Slant" series of speakers to replace the Centaur hybrids. Two speakers were made to replace the three speakers previously manufactured.
1998 The last of the Apogee hybrid speakers were the Cepheus 6 and Cepheus 8 which were replacements for the Slant 6 and Slant 8 respectively. The Auriga, Perseus (LCR), Cassiopeia, and Capella were also made around this time. Apogee was bought by ADS Technologies. They continued the Apogee speaker line for a short period of time. Due to a patent issue with Magnepan they ceased production, support and the supply of replacement parts.
1999 ADS closes Apogee Acoustics as it is considered not commercially viable, leaving owners without spares support, Matt Carnicelli starts the Apogee Acoustics Users Group.
2001 Graeme "Graz" Keet reforms Apogee Acoustic's and starts supplying revised upgraded spares for the majority of the Apogee line improving the original performance using proprietary CNC ribbon machining equipment.
2003 Establishment of Apogee Acoustic's local service centres commences. Operators trained by Graz to repair clients speakers with exclusive agreements to use Graz revised Apogee Acoustic's parts, and installation procedures within their regions. First in the UK, then Switzerland, The Netherlands, East Coast USA, Germany, West Coast USA, ongoing.
2004 Apogee Classic speaker build service offered, and "special products" new reference Apogee Acoustic's Definitive speaker announced, taking the classic Apogee visual appeal, but adding massive structural rigidity and considerably higher efficiency. Late 2004 sees the introduction of KLM2 & XLM2 series Mid/tweeter ribbon parts available for Apogee speaker owners worldwide, for either home or installer installation
2006 Ability to use the www.apogeeacoustics.com domain granted by title holders for the first time.
