Infinity 7 Kappa loudspeakers

 

A New Generation Of High Accuracy Technology

The Kappa woofer has a highly innovative cone that is injection molded from a mixture of graphite fiber and polypropylene. The advantages of these two materials - graphite for its stiffness and polypropylene for its inertness - compliment each other. During the high pressure injection molding process, graphite fibres are forced into the polypropylene in a radial pattern. This composite structure exhibits extreme stiffness and pistonic operation up to nearly 1 kHz, low mass, fast acceleration and very high self damping. The result is taut, precise bass reproduction at all volume levels, with sufficient bandwidth to permit very smooth transitions to midrange drivers. We use the same composite cone (and the rigid cast frame of the heavier 12" Kappa woofer) in our no-compromise Infinity Reference Standard, Series V and we believe that it is the most accurate cone made - at any price.

Our revolutionary Polygraph k superwoofer handles the critical mid-bass and lower midrange frequencies. The spectrum of 80 Hz to 800 Hz where half of all musical energy appears and where most speakers are at their weakest. This new 5" dome-shaped driver operates throughout this range and delivers a seamless, coherent performance. Allowing voices and instrumental textures to emerge with an airiness and clarity that is musically convincing.

Diaphragm construction on the Polygraph k is more akin to that of a grand prix car than a loudspeaker. It is a composite structure, made from unusually thin polypropylene supported by an extremely stiff lattice of graphite fiber. These two materials provide an unprecedented combination of stiffness, low mass and damping. The Polygraph's transient response and resistance to breakup rivals that of the most expensive planar drivers. Its power handling and dynamic range surpass them.

The equally important upper midrange frequencies are covered by another new dome design. Our 3" Polydome k uses an edgewound voice coil for high electrical efficiency and a new formulation of soft polypropylene for a combination of excellent self damping and speed. Our research paid off in a driver of exceptionally low coloration. This dome mates beautifully with the potent Polygraph k and, because of its size, can go low enough to meet the 10" and 12" kappa woofers in our more affordable 3-way systems.

The higher frequencies still belong to our famous EMIT electromagnetic induction planar tweeters. Now, however, there are two of them, and both feature evolutionary improvements first used in our IRS, Series V.

 

Compared to its predecessor, the Kappa EMIT has a kapton diaphragm of approximately half the mass, a lighter, thinner aluminum trace (analogous to the voice coil on conventional cones and domes) and new ultra-linear, ultrahigh gauss rare neodymium magnets. High frequency response has been extended to 44 kHz, and though you won't hear fundamentals up there, you'll find that kind of bandwidth makes a difference in reproducing transients and instrumental attacks. In our more expensive 8 k and 9 k loudspeakers two of these EMIT k's are used - one in front and one in the rear - for true dipolar dispersion and superior imaging.

 

Reference Standard 7 Kappa

The 7-Kappa is a stylish 12" three-way floor standing loudspeaker system. It's cast frame woofer utilizes our graphite fiber reinforced polypropylene cone coupled directly to the superb Plydome k, a 3" soft polypropylene dome. And improved EMIT k tweeter uses the same light diaphragm and neodymium magnets as our other Kappa speakers. These drivers are housed in a handsome cabinet which, with its rounded front and rear vertical edges, looks right at home with the finest furnishings. This combination of larger woofer and greater cabinet volume provides deeper, more powerful bass than the 6 k, along with greater power handling and dynamic range. The enclosures modest footprint contributes to ease of placement - even in confined living quarters.

Infinity 6 Kappa loudspeakers

Kappa is a concept and group of products. Five unique drivers and four loudspeakers that incorporate them. Kappa speakers differ radically from conventional speakers in appearance, underlying design philosophy , and certainly in performance.

Woofer.

A newly developed composite polypropylene/graphite fiber injection molded cone enables Kappa woofers to produce powerful, taut bass.

Mid-range

Utilizing a 3" edgewound voice coil and a powerful magnetic structure, the new Polydome k midrange driver delivers low distortion, exceptional linearuty and fast transient response.

Tweeters

New neodymium magnets and a special ultralight diaphragm extend the EMIT k tweeter's bandwith to beyond 44 kHz. The result is incredibly fast transients within the audible frequency ranhe.

Network.

Kappa crossovers are computer designed, then carefully handtuned during critical listening sessions. Components are chosen for their electrical excellence and musicality.

 

Reference Standard 6 Kappa

The 6 Kappa is a monitor-size loudspeaker that performs properly on the bookshelf or, with its optional pedestal, the floor. Low frequencies are reproduced by our 10" graphite/polypropylene woofer, mids are handled by our new 3" Polydome k and high frequencies are handled by our improved EMIT k. in virtually all aspects of performance, aside from extreme bass extension, the 6 k surpasses European and American monitor systems costing up to three times the price. The linearity of its Kappa drivers and their integration - through a high quality computer optimized crossover network - provide for notably higher resolution than is possible with conventional drivers. The 6 k is a fitting complement to the best electronics and signal sources and forms the foundation of an affordable perfectionist audio system.

Infinity ES-1 headphones

The most acurate headphones ever created. That was the goal.

When Infinity's scientists set out to develop such a stereo component, we determined to start from the highest achievement to date in headphone reproduction - electrostatics - and to remove the previous limitations of electrostatics.

The ES-1 Headphone System demonstrates that accomplishment. And no longer are the finest headphones any less accurate than the finest speakers.

An altogether new diaphragm material is employed in these headphones because it follows dynamic changes much faster and more precisely than the polyester others use. This extremely low-mass material, called Polyurethin, is so responsive as to provide a transient fullness impossible to achieve in the past.

 as a result, Infinity's electrostatic headphones deliver a frequency response of 20 to 25,000 Hz ±2 dB; at a sound pressure level of 100 dB; they show total harmonic distortion of less than 0,3%; their maximum output is a full 118 dB SPL; the realism of their reproduction is startling.

The ES-1 Headphone System consists of one headphone set and the walnut-enclosed adaptor containing power supply and matching transformers. Front-panel output connectors accommodate two headsets; an optional second set is available from your Infinity dealer.

The power supply is to be connected between your amplifier and speakers. Front panel switchingwill let you leave your headphones connected whether you are listening to them or to your speakers. Power supply is also provided with a fast-acting protection circuit to switch off either channel or both in case of overloading that might otherwise damage the unit. A re-set button on the front panel easily puts the circuit back into operation.

Infinity Electrostatic Headphones operate in the push-pull mode, that is, the power amplifier's signal is boosted by the transformer, and constant bias (DC) voltage sets up electrostatic fields which push and pull the diaphragm between two grids.

Infinity coats the Polyurethin of the diaphragms precisely evenly with conductive chemical compounds. The material and the process deliver three benefits:

A high "ratio of extension", the ability to respond to the smallest signal variations and return instantaneously to original tension. Infinity has achieved a marked improvement over polyester, which is 20 times heavier than Polyurethin.

Reduction virtually to zero of the distortion that can be caused when energy is reflected at the suspended edge of a headphone diaphragm.

Voltage spread evenly over the entire diaphragm surface so it will move as a perfect piston with no "hot spots" moving sooner or more than other portions.

As with every Infinity product, the purpose and the result of our using the most advanced technology is to deliver the original, uncolored sound of music exactly as recorded. In the case of the ES-1, you experience a spacious, open quality. Not only can you hear sounds around you (baby's cry, doorbell), but in addition, the music seems to be spread naturally all around you, and not focused unnaturally inside your head.

Your private listening experience with Infinity Electrostatic Headphones will be gratifyingly comfortable, supremely accurate, and totally musical.

Infinity Reference Series 61i

Reference Series The Next Generation

In an era when pride in quality craftsmanship, independent creative thinking and conscientious attention to detail seem to be rapidly vanishing from almost every field of consumer goods, Infinity continues to lavish our unique blend of tender loving care and cutting edge engineering on every loudspeaker that bears the Infinity logo.

Most recently, we turned our attention to the popular Reference Series with an eye toward further elevating the already exceptional level of performance of this fine range of loudspeakers.

The result is Reference Series II - The Next Generation, quite simply one of the finest loudspeaker lines ever introduced. The second generation Reference Series loudspeakers represent substantial improvements in key areas such as efficiency, power handling and in both the quantity and quality of deep bass. One of the major contributing factors to this giant step forward is the introduction of drivers which incorporate proprietary APG lightweight cone technology, allowing them to respond to musical waveforms with amazing accuracy.

With higher efficiency, increased power handling and enhanced low frequency output, the new Reference Series is ready to take on any sonic challenge, from chamber melodies to operatic climaxes, from cheerful Aladdin to fearful Jurassic Park.

The Second Generation Reference Series incorporates:

Space-age APG driver technology with carbon and Kevlar fibers.

Super-light cones for improved sensitivity.

Low insertion loss crossovers for improved transient response.

Increased internal volume for extended deep bass response.

Rear-mounted port for undistorted bass response.

Crossover optimized for uniform phase response both on and off axis.

Internal bracing for reduced resonance.

Strategically placed internal damping to eliminate standing waves.

Sloped cabinet for reduced diffraction.

Redesigned grille for optimum vertical and horizontal dispersion.

Spikes for decoupling of floor-standing models.

Finest furniture craftsmanship. Sleeker, slimmer enclosure design.

APG cone technology

Without a doubt the most revolutionary innovation in the Reference Series is the implementation of a specially formulated graphite coated APG (acrylic polymer graphite) cone which combines the excellent internal damping of acrylic polymer with the stiffness of graphite. Extensive subjective and objective testing confirms that APG represents a major breakthrough in cone materials technology with stunning performance in terms of low distortion, linear frequency response, spacious sound and overall musicality.

The exclusive APG process aligns carbon and Kevlar fibers precisely along the polymer matrix, allowing total control over the contour and weight of the cone, while making it possible to create a lightweight cone with varying thickness, for greater dispersion of sound. Carbon and Kevlar fibers are embedded in an APG matrix in carefully controlled proportions. Following oven heating, the compound forms an extremely rigid, ultra-lightweight and super-strong composite cone material with maximum internal damping which offers a significant reduction in distortion caused by colorations, vibration and break-up modes. The sonic benefits of the fast transient response and high sensitivity of the new lightweight driver cones are readily apparent in the astonishing openness, lucidity and harmonic fidelity of the Reference Series loudspeakers. Their crisp, detailed sound is the result of innovative materials and driver technology unrivalled in contemporary loudspeaker engineering.

High sensitivity

Since APG cones are 30% lighter than paper cones of equal stiffness, Infinity engineers could design the new Reference Series with higher efficiency, without employing heavier, more costly magnetic structures.

The high sensitivity of the Reference Series loudspeakers, with highly efficient magnetic systems, super-light cones and low insertion loss crossovers, means far less work for your amplifier. Since amplifier distortion increases with higher power output, reducing power demands also yields a significant reduction in distortion.

Since lightweight cones respond more rapidly and linearly to transients, the rigid, high-tech cone materials employed in the high efficiency Reference Series dynamic drivers offer enhanced transparency, improved resolution of low level detail and of the ambience cues which create a wide and deep soundstage. An increase of 3dB in sensitivity reduces by 50% the power required from your amplifier to achieve the same sound pressure level.

Sophisticated crossover

The new Infinity Reference Series' low insertion loss crossover networks employ select-grade components in o crossover configuration designed to preserve signal integrity and efficiency.

Crossover design assisted by state of the art. computer technology and controlled by  extensive listening tests ensures optimum linearity combined with lowest distortion and the finest sonic quality.

The high efficiency of the crossovers permits  the use of Reference Series speakers in high power applications, including demanding home theater systems.

Enclosure design

In the new Reference Series loudspeakers  radical steps have been taken to eliminate the "boxiness" normally associated with conventional cabinet construction.

The midrange drivers are installed in separate air-tight compartments filled with special damping material to provide smooth, linear reproduction of the crucial midband.

Internal bracing and damping reduce the deleterious effects of resonances and standing waves. Front baffle diffraction phenomena, which typically introduce smearing in the time domain, are reduced through the implementation of an optimized grille shape and through tapering of cabinet top and sides. Rear-mounted bass reflex ports minimize noise, while providing extended, punchy bass.

The Reference Series speakers in Chatsworth Oak or Black Ash vinyl are finished to the highest standards of furniture craftsmanship and their sleek contemporary "Tower" look will match most interiors.

 Reference 61 i

The top of the line Reference tower includes spikes for effective decoupling from the floor and gold-plated terminals for long-term purity of signal transmission. The Reference 61 i adds a second 210 mm APG woofer to the driver complement found in the Reference 51 i, further extending low frequency response and power handling with two woofer voice coils to share the workload.

The 25 mm APG-coated dome tweeter minimizes break-up of the radiating surface across its operating range for smoother, more natural high frequency response with very low distortion. The mechanically isolated 25 mm unit reproduces the midrange with outstanding clarity and definition.

The Reference 61 i brings music to life with a new fullness and richness.

Infinity 1001A

The Infinity 1001A is a cosmetic update of our already famous 1001. the 1001A has received a new enclosure with a dramatically sculptured grill consisting of distinctive knit fabric. The sonic features of this system remain unchanged. High Fidelity Magazine said of the 1001, :the Infinity 1001 negotiated even the most demanding orchestral material with ease, conveying a sense of excitement not often experienced with systems in this price range."

The Tweeters

The Infinity 1001A utilizes two exceptional cone tweeters; one in the front (the transient tweeter) and the other in the rear of the enclosure (the ambient tweeter). The front (or transient) tweeter gives the direct radiation with its transient information to yield sharpenss and clarity to the sound. The rear (on ambient) tweeter adds complete dispersion of the high-frequency radiation to re-create the true instrumental character actually in space, rather than in a flat plane. The two tweeters are coupled together through a special phasing and frequency contour network which maintains the energy response beyond 20 kHz without the usual high-frequency beaming that imparts stridency to the music. This effect can be had with the enclosures placed no more than an inch from the rear wall; however, a more dramatic and realistic effect can be had with at least six inches separation from the rear wall.

The Woofer

Another unusual feature for this price system is the bass section. A specially designed twelve inch woofer is utilized. The woofer itself undergoes two separate and distinct treatments. Firstly, the soft paper cone is permeated with a plasticizing agent which adds enormous stiffness to the cone. Secondly, thick asbestos  compound is applied to damp out spurious modes produced by increasing the stiffness. Essentially all spurious modes and resonances are thereby removed so that the speaker acts as a superb piston even throughout the critical midrange area.

The treated woofer is then utilized in our famous transmission line enclosure. This enclosure design exhibits a very uniform impedance characteristic yielding non-resonant bass with none of the familiar hangover of the acoustic suspension designs.

Another reason for the extremely natural quality of he Infinity 1001A is that no inductors nor any other crossover network is used with the woofer. It was designed with exactly the correct phase and frequency response characteristics to meld smoothly into the tweeters.

Infinity Reference 31i

Infinity Reference 31 i

The floor-standing Reference Series utilizes spikes for optimum decoupling from the floor, resulting in tighter bass and more detailed midrange. Based on the same 210 mm woofer and 25 mm tweeter as the Reference 21 i, the Reference 31 i exploits its larger cabinet volume to achieve higher levels of bass at still lower frequencies for an even more natural sounding, more solid deep bass foundation.

The specially shaped grille and tapered top and sides of the enclosure eliminate diffraction which could otherwise muddy or blur the aural image.

Infinity Black Widow Tone-arm

 The only thing better would be no tone arm at all.

The ideal record-playing system, theoretically, would be simply this;  A cartridge suspended from an infinitely rigid nothing, which would take some of the cartridge's weight off the stylus, leaving the optimum tracking pressure; obviously create and transmit no resonance of its own;  and leave the stylus in proper position against both sides of the record groove, wherever that groove might lead (up and down on a warped disc, back and forth on an imperfectly centered one) without a heavy counterweight to resist first and overcompensate an instant later.other tone arms have achieved proper vertical tracking force - period.

Infinity introduces the closest approach to the entire ideal.

The first tone arm designed by Infinity is an eceptionally rigid leverwhich is extremely low in mass especially toward the stylus end, where the conventional head shell has been eliminated; impeded at the point where the arm's diameter changes, creating a transmission line that effectively breaks up any incipient resonance; and minimal in arm weight and counterbalance weight.

This advanced audio component will improve the operating specifications of any modern cartridge, and reveal inner voicings and an openness you have never heard before in your favorite recordings.

We call this slender wand The Black Widow. And we eagerly invite you to compare it with other tone-arms. The Black Widow will eat them  alive,

 A phonograph record is not a precision instrument. So the Infinity Black Widow has to be.

Records aren't perfectly flat or perfectly centred. But no other manufacturer of tone arms has fully dealt with that fact. So what happens? With an ordinary tone arm, every time a warp in a disc forces the stylus up, the combined mass of arm plus head shell plus correspondingly heavy counterweight creates a distorting press-and-release, press-and-release action of the stylus.

And during every revolution of the disc, with the "center" hole and/or grooves actually off-center, that inertial mass forces the stylus against one side of the groove and then the other.

These forces can cause mistracking and distortion, as well as degrading the crosstalk and spoiling the accuracy of the stereo image.

Moder lightweight high-compliance cartridges could never perform up to their potential and their manufacturers promises until somebody removed the inertial stubborness and excess weight from a tone arm.

Our tone arm won't add tones to those already on your record.

As a turntable rotates, and as the stylus in the cartridge on the tone arm is excited to reproduce an array of frequencies, most tone arms feel an overwhelming urge to add vibration and resonances of their own.  Infinity has at last eliminated that source of distortion.

Where the circumference of our Black Widow Tone-Arm changes, a transmission-line effect is created; that is, resonances are neither passed along nor reflected back to the stylus, but instead are attenuated at the barrier.  Perhaps all tone arms should be designed the way ours is. But only ours is.
