1955 Mr. Bill Hecht was keenly aware of the huge potential of film sound reinforcement systems in the home market, and he established United Speaker Systems, developed the Premier 100 series of audio products in the garage at home, and put forward the “Theater Sound for "The Home" slogan-This is the first "Home Theater" advertisement recognized in the history of the audio industry. Since then, home audio has officially entered the theater era from the radio and stereo era! And Mr. Bill Hecht and his Premier series are the pioneers of this era.

1957 Mr. Bill Hecht’s USS started to produce Premier 100 series home theater speakers at a rate of one set per week, and received wide acclaim from audio dealers and users in New York and surrounding markets. Mr. Bill Hecht quickly developed the Premier 200 series. For the first time, the back of the cabinet was designed in a right-angled shape, which can be placed in the corner of the room very conveniently. The low-frequency reflection of the room was used to greatly enhance the sense of sound field enclosure. Once launched, it was widely praised by the market and sales increased greatly.

1958 The American "Hi-Fi Audio" magazine gave a detailed introduction and evaluation of the Premier series of speakers. The editor-in-chief of the magazine gave a very high evaluation. "This is the best home audio I have ever heard. The accuracy of the sound is comparable to that of a commercial theater. Sound quality effect". The popularity of Mr. Bill Hecht and USS skyrocketed, and the products began to be sold throughout the United States. USS began to become one of the main brands in the audio market.

1959 The classic model Premier 500 series was released, and a series of customizable styles were also introduced. Different cabinet materials, colors, and mesh materials and colors can be customized according to customer preferences to match different decoration styles in the home. Mr. Bill Hecht's amazing vision opened the era of customized audio. Today, how to better match the audio system with the home environment is still one of the focuses of the industry's development.

1959 After World War II, the largest radio and amplifier manufacturer in the United States, New York Fisher Radio Company, which used German military radio and audio technology to rapidly rise, was planning to enter the speaker market. The owner of the company, Mr. Avery Fisher and Mr. Bill Hecht, decided to cooperate. The legendary model Fisher XP-1 bookshelf speakers went on the market soon, with sales exceeding 10,000 sets that year, and Fisher became one of the most important home audio brands in the United States.

1962 随着Fisher（美国飞燕）在家用音响市场上的巨大成功，又有3个品牌（EV、DYNACO、BOGEN）开始选择将音响业务完全委托给USS（美国联合音响系统）公司进行设计、研发和生产，年产量迅速超过了10万台。1962年，USS（美国联合音响系统）公司在New Jersey（新泽西州）的BellVille（贝尔维尔市）开设了第二个音响制造工厂，设计年产量为30万台。

1965 Mr. Bill Hecht's first invention patent was US Patent#3177301 Sound Translating Device in 1965, which laid the basic structure of today's audio unit, improved the sound accuracy of the bass unit, and reduced the distortion. This patent raised the sound quality level of the speakers developed and produced by USS to an extremely high level, and became the recognized "The Manufacturer's Manufacture" in the audio industry.

1969 Due to Mr. Bill Hecht’s two key US invention patents, he almost monopolized the most advanced woofer and tweeter technology on the market at that time. The four major Japanese audio brands, YAMAHA, JVC, Pioneer, and SONY, have successively developed and produced audio business Entrusted entirely to USS, the third audio factory with an annual output of 300,000 sets was soon put into production in East Orange, New Jersey.

1969 Mr. Bill Hecht quickly upgraded the high-frequency performance of the loudspeaker and obtained the US Patent #3482062 Damped Electro-Acoustic High Frequency Transducer. The mid- and high-frequency acoustic performance of the woofer has been raised to a new level, continuing to lead the industry.

1976 Mr. Bill Hecht invented the Self-damping woofer voice coil patent and the Silicone-injected drivers for resonance damping patent, which reduces distortion and improves sound accuracy.

1977 Mr. Bill Hecht invented the patent of The basket-less woofer/midrange driver mounting system, which makes the installation position of the speaker unit more flexible when designing the speaker, and the appearance is more concise and beautiful.

1978 Mr. Bill Hecht was the first in the world to apply Ferro-Fluid technology to the design of audio units, which further improved the high-frequency expressiveness of the tweeters. Today, this technology is still the industry standard.

1979 Mr. Bill Hecht developed the world’s first Flat Solid-Piston Driver, which has three revolutionary advantages: First, the phase of the outer ring and the inner ring of the traditional cone unit is inconsistent, resulting in poor stereo phase accuracy, mid-to-high frequency The problem of sound "stain". The plane unit vibrates and emits sound on the entire plane, and all positions are in the same phase, resulting in a smoother, clearer and more stable sound field positioning. Second, the ultra-light and rigid piston structure of the plane unit will not deform at all during work, which solves the deformation and distortion of the traditional cone unit during high-speed and large dynamic vibration and the nonlinear off-axis motion failure of the voice coil, collectively referred to as the basin split problem . Third, the RPF solid diaphragm of the planar unit has excellent sound blocking characteristics, which solves the problem of the traditional cone unit diaphragm being thin and unable to isolate the reverse sound wave from propagating forward through the cone during operation. For many years since then, USS is still the only audio manufacturer capable of producing flat units among the three in the world and the only American manufacturer. Note: The other two are British PMC and French Focal.

1981 The fourth fully digital factory was officially put into operation in Jacksonville, Florida. It used the largest 8.5-ton 4-head CNC machine tool in the global audio industry for the production of speaker cabinets. It can process various streamlined cabinets with high precision every year. 200,000 pieces. MITSUBISHI, KENWOOD, and JCPenney began to commission USS to carry out audio research and production.

1983 Masato Sagawa of Japan's Sumitomo Special Metals discovered the neodymium iron boron magnet for the first time in 1982, the most magnetic permanent magnet in the world so far. In 1983, Mr. Bill Hecht was the first in the world to apply Neodymium-iron-boron to the sound unit design. Today, high-magnetic NdFeB is still the permanent magnet technology standard in the audio industry, and is widely used in high-end audio unit design and earphone design.

1983 After the establishment of the PHASE brand, a new model PC60 of the Premier series was released, and "Better Sound Through Advanced Technology and Construction" was proposed, using three exclusive technologies: patented flat solid piston unit, Absolute Faith wide sound field crossover, and patented soft dome Tweeter. The series includes a pair of PC60 6.5-inch woofer and 1-inch tweeter bookshelf speakers and a PC50 10-inch omnidirectional bass speaker. Available in light oak, dark oak and walnut wood cabinet appearance materials. It was named the best bookshelf speaker in 1983 by the American "Stereophile".

1985 After the PHASE brand was founded, the second product line, the Custom Installation series, was released. The three successful PC series technologies were all geniusly applied to the wall-mounted speakers, which became a new custom installation in the United States at that time. Innovative pioneers and star products in the market. This series also applies the Dog Ear Automatically Clamps patent. When installing in-wall speakers, you only need to twist the speaker buckle with a screwdriver, and it will automatically pop up and clamp, which greatly improves installation efficiency. This patent is still used in almost all custom-installed speakers and has become the de facto industry standard.

1993 Mr. Bill Hecht invented the Neodymium Ferrite Boron Magnets Tweeter, which provides top high frequency performance and minimal distortion, which is very suitable for the latest digital media sources, such as CDs. This technology is still one of the best tweeter designs today.

1994 PHASE released the flagship product of the Premier series, PC9.5 four-way floor-standing speakers, which fully utilized all the high-end technology of PHASE at the time, 1 inch neodymium iron oxide boron permanent magnet soft dome tweeter, 1.5 inch soft dome midrange unit, 6.5 inches Mid-bass flat Kevlar unit, dual 6.5-inch bass flat Kevlar unit, Absolute Face wide sound field crossover, etc. This series is specially designed for top audiophiles. Once launched, it has won numerous awards and has sold more than 150,000 sets worldwide. This series also includes PC3.5 three-way LCR speakers, PC1.5 two-way bookshelf speakers, PC-SURR three-way surround speakers, etc. It is widely suitable for all kinds of stereo music and surround sound cinema.

1995 Mr. Bill Heckert invented the Unicell Zero-Diffraction Treatment patent, which is used to reduce the acoustic reflection and diffraction between the speaker tweeter and the grille, and further improve the high frequency directivity and sound field positioning accuracy.

1995 Mr. Bill Heckert invented the Positive Clamping mounting system patent. The speaker frame is an all-metal structure. The mounting clip structure is replaced with a right-angled metal edge strip with the same length as the speaker. Any type of wall and speaker frame are clamped by screws. At the same time, this simple but extremely strong fixing method completely eliminates the impact of any speaker vibration on the installation wall.

2001 Mr. Ken Hecht, from the 2000s, officially began to preside over the development of new materials, new technologies, and new products. In 2001, he formally invented the Nomex&Glass fiber three-layer composite unit. The cone material is extremely strong and light in weight. Effectively avoid the phenomenon of basin split, almost no distortion, is by far one of the best woofers in the world.

2002 Mr. Ken Hecht, formally invented Silk-Titanium Tweeter, which not only retains the sweet and sweet characteristics of the silk diaphragm material, but also increases the detail expression and gloss of the titanium material. It can be called the perfect work of the top tweeter.

2003 At the CEIDA exhibition in the United States, PHASE released the world's first wall-mounted subwoofer IW-200 and supporting dedicated power amplifiers, officially bringing the subwoofer category into the era of custom installation. Not only has it received wide attention and praise from participating professionals, but also won the 2003 Most In-Wall Speaker Exhibition Award.

2008 PHASE has released the new Custom Installation series. All ceiling speakers and embedded wall speakers in the entire series adopt the latest invention of Mr. Ken Hecht, the Quick Mount System. This technology makes the installation of the speakers easier and safer, greatly improving the installation Work efficiency, widely praised by distributors worldwide, has become the industry standard today.

2014 PHASE released the PC60 CA (Classic Audiophile Edition), as the 30th anniversary limited edition of the 1984 PC60, the first batch of 500 pairs worldwide, using the latest flat Kevlar woofer, high-performance soft dome tweeter, The American oak cabinet kept the shape of the 1984 edition, and even recalled the assembly workers of that year, in order to pay tribute to PHASE's most classic bookshelf box PC60. Once it was launched, it was highly praised by many media around the world. John Atkinson, the editor-in-chief of Stereophile magazine in the United States, gave a 5-star recommendation in the cover report: “PC60 CA strongly attracted me, even though I have been doing audio equipment for 30 years. I’ve been attending various audio exhibitions for longer, but I’ve never been so shocked. PC60 CA is the most recommended bookshelf Hi-Fi speaker in the past 10 years! I also bought a pair at home!"
