Infinity Systems

Infinity Systems is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Infinity Systems rather than just read about it. In short: Infinity Systems is an American manufacturer of loudspeakers founded in Los Angeles in 1968 and headquartered in Stamford, Connecticut. Since 1983, Infinity has been part of Harman International Industries, which became a subsidiary of Samsung Electronics in 2017.

Key takeaways

Infinity Systems belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Infinity Systems to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Infinity Systems from memory before moving on to harder problems.

Reference excerpt

Infinity Systems is an American manufacturer of loudspeakers founded in Los Angeles in 1968 and headquartered in Stamford, Connecticut. Since 1983, Infinity has been part of Harman International Industries, which became a subsidiary of Samsung Electronics in 2017. Infinity produces packages for a range of audio applications, including multichannel surround sound home theatre packages, in-wall home speakers, and marine applications. Other products include powered subwoofers and car audio amplifiers. Infinity products are installed as an option on Hyundai and Kia vehicles, some Mitsubishi vehicles from the 1990s to 2006, and many Chrysler vehicles.

History Founded in 1968 by Arnie Nudell, John Ulrick and Cary Christie, Infinity has produced home and mobile audio products by employing innovative materials such as neodymium magnets, mylar diaphragms, and polypropylene cones. The company's first product was the Servo-Statik speaker system. Infinity had an ownership relationship with Eastern Air Devices, later known as EAD. This involved the consumer brand of KLH speakers, and Avid< Peerless drivers, and Kyocera/Cybernet (which produces electronics) In the late 1970s Infinity introduced the EMIT (electromagnetic induction tweeter) and EMIM (electromagnetic induction midrange) drivers. These were flat quasi-ribbons that worked to move air based on the principle of electromagnetic induction. The system used samarium–cobalt magnets, allowing for a very low ribbon driver mass-per-unit area. Variants were made, such as the EMIT-R (radial emit), the S-EMIT (super emit) and the L-EMIM (large emim). The IRS (Infinity Reference System) was an ultra-high-end system, selling at US$65,000 in the 1980s. It consisted of 72 EMIT tweeters, 24 EMIM midrange drivers, and twelve 12-inch polypropylene woofers in four towers. In the mid to late 1970's Infinity made the Monitor II 4-way speaker using the unique Walsh Transmission Tweeter. The Walsh tweeter looks much like a conical Ice Cream Cone (a traditional shape for an American confection (food)). The principle for the cone shape is to cause the typically directional High Frequencies to be emitted form the cone surface in a 360-degree horizontal dispersion pattern. Said to enhance the listening. Each Walsh Transmission tweeter was handmade. Nudell left to form Genesis Technologies, a high-end loudspeaker company, founded in Seattle in 1991. Genesis' original flagship system, the 1.2, retailed for US$235,000, and is basically an updated Infinity IRS system. After the departure of Nudell, Infinity speaker designs took a more mass market-oriented approach. The efficient SM (Studio Monitor) series incorporated a polycell tweeter and graphite-impregnated midrange/woofers. While not as elaborate or high end as previous Infinity efforts, they filled a popular consumer niche.

Worked examples

Example 1 — a first encounter with Infinity Systems

Start with the simplest possible case. Write down what Infinity Systems claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Infinity Systems before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Infinity Systems ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Infinity Systems

In research: Infinity Systems appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Infinity Systems in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Infinity Systems is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1968 establishments in California, 1983 mergers and acquisitions, Companies based in Stamford, Connecticut, so understanding it makes those chapters shorter.
In everyday life: Look for Infinity Systems outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Infinity Systems in simple terms?

Why does Infinity Systems matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Infinity Systems?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
