SIGNATURE i93MKllI - NEW

The much loved and highly popular Signature i93 has undergone a refit. Our design team have been hard at work developing a completely new electrical cross over topology and incorporating a new Norwegian proprietary Magnesium Alloy tweeter.

The result is a level of accuracy and performance rarely seen in a loudspeaker at their price. This accuracy results in transparency, imaging, detail, sound staging and dynamic subtlety that convincingly convey a realistic and true-to-life listener experience.

The bass detail and precision is raised to a new level, not bad given Rolling Stone had already described the i93 as " the ultimate in hi fidelity with the best bass in the world". The VAF Signature i93MKIII is additionally one of the few production non active loudspeakers truly able to reproduce accurate and low-distortion bass to 20Hz. In many rooms they will reproduce bass down to 17Hz at only -6dB.

Overall music presentation is smooth and balanced, with the speed and accuracy VAF is known for.

VAF is famous for delivering performance at a price considerably less than other imported products. In keeping with this legacy, the i93mkIII offers a huge amount for a lot less than you'd expect - but we always want more. For those with a little more in the budget you can purchase the I-93MKIII in it's standard configuration OR in an SE version.

i93 SignatureMKIII SE.

The SE version for the i93MKIII is something very special. We've gone all out including matched super refined high speed Beryllium tweeters, high density loaded cabinetry increasing effective mass by over 25%, high speed capacitors in the critical signal paths, silver soldered terminations, heavy gauge high quality Analysis Plus internal cabling.

This is the finest speaker we've ever built. Period.

The VAF Signature i93 is at home in the highest fidelity stereo system. Uniformity of design process across the entire VAF Signature Series also ensures that other VAF Signature Series models can be used in harmony with the VAF Signature i93 to create a multi-channel surround sound theatre system without peer.

DESCRIPTION

The VAF Signature i93MKIII is beautifully crafted to the highest standard in finely finished genuine timber veneers and weighs in at a massive 100kg.

Featuring a time-aligned vertically symmetrical driver array, the VAF Signature i93 is a floor standing five driver, three way loudspeaker. Each cabinet contains two 210mm woofers and two 130mm magnesium alloy cone midrange drivers, symmetrically arrayed about a single 25mm double chamber magnesium alloy dome tweeter or in the SE model hand matched Beryllium tweeters.

Each woofer cone is constructed of composite hard paper pulp embedded with carbon and Kevlar fibre which are individually treated with an anti-resonant natural fibre. Each midrange cone is precisely and individually machined from forged magnesium alloy.

Both the woofers and the midrange drivers have low distortion, long linear throw motor systems. They employ precision engineered copper shorting rings, both in front of and behind the forward magnetic pole plate. Solid copper phase correction plugs are embedded within large, double layer voice coils.

Copper coated magnetic circuits are also used to eliminate induced eddy currents, so that even these often ignored minor effects do not intrude or contaminate the sound.

The tweeter is also unique, comprising a 25mm pure silver voice coil driving a proprietary Magnesium Alloy dome backed by it’s own anti-resonant triple chamber acoustic backing.

All drivers are time aligned to optimise phase and impulse responses, and therefore maintain exact spatial recreation of the original sound wave front as it was recorded. Time alignment is critical to maintain the correct reproduction of the highly complicated harmonic structures created by musical instruments.

Optimised internal damping is provided by VAF’s advanced HyperSoft acoustic material, to effectively eliminate internal cabinet reflections and standing waves that interfere with the correct operation of the drive units.

An obvious and integral design feature on every VAF loudspeaker is natural, acoustically absorbent fibre pads. These are fitted around each tweeter and midrange driver to accurately control dispersion and effectively eliminate diffraction effects – another source of distortion and colouration of the reproduction.

Manufactured from only first grade MDF up to 52mm thick, cabinet construction is highly detailed. Precisely fully mitred joints and substantial internal cross-bracing characterise the superior quality of these loudspeakers.

Finishes include stunning high quality piano gloss or satin lacquer on crown cut, book-matched, genuine timber veneers including Australian Jarrah, Cherry, Black Oak and American Oak. A black lacquer in satin or piano gloss finish is also offered at extra cost. All of our speakers are made here in Australia, as such custom and bespoke finishes are available on request.

TIME SYNCHRONISED ARRAY

While very uncommon, and much more complex as well as expensive to build, use of Time Synchronized Arrays are the only way currently possible for a loudspeaker to sound natural (accurate). Time synchronized arrays in loudspeakers feature 3 critical components. 1) Time alignment of the speaker drivers, 2) even total power response (how evenly the speaker radiates its sound into a room), and 3) the type and tuning of the filters in the loudspeakers electrical crossovers.

TIME ALIGNMENT

Time alignment is achieved by stepping the various drivers (Woofers, Tweeters, Midranges) on the front of the speaker so that the acoustic centres are the same distance from a listener. For this to be effective a special kind of electrical crossover must also be used. All VAF loudspeakers are time algned.

SHAPED VERTICAL & HORIZONTAL POWER RESPONSE

VAF engineer the power response of all its loudspeakers to radiate sound as evenly as is possible for each model. In this way the proportion of bass, mid and treble in the direct sound correlates more closely with the proportion of bass, mid and treble in the reflected sound and the listeners brain can correlate the two making the speakers less effected by a rooms acoustics and easier to place in a room.

STORED ENERGY DAMPING

All speakers take a moment to stop making sound (decay). The faster a speaker stops making sound the less that sound ‘blankets’ sound which follow it, or finer details in the sound. The more evenly the bass, mid and treble decay the more consistent the ‘pitch’ of the speaker. VAF loudspeakers are among the very few in the world that engineer for fast and even decay in all its incarnations. This includes diffraction, cabinet resonances, internal cabinet sound reflections, stored energy in electrical crossovers and more.

DIFFRACTION CONTROL ABSORBERS

Double Layer Diffraction Control As sound moves across the speaker baffle, it reflects or diffracts off the baffle and baffle edges. Twin layers of diffraction control material effectively stop these destructive reflections before they even happen.

DIFFRACTION CONTROL CAVITY RESONANCE CHAMBERS

Along with Diffraction Control Absorber, larger VAF Signature speakers feature the addition of resonant cavities in the diffraction absorber which significantly increase the frequency range over which the absorber operate.

STEERED REAR WAVE ATTENUATION

VAF loudspeakers are designed to steer the rear energy in a way that transmits it as far away from the driver as possible while also ensuring that energy passes through internal cabinet damping as many times as possible before ultimately returning to the driver. In this way much more rear energy is damped and hence does not re-radiate into the room. The result is a more pure sound.

OPTIMUM Q FILTERS

As no driver is perfect good crossovers also equalise and shape the response of each driver as well as the overal response of the speaker.VAF use a particular type of design aproach which minimises the unessesary stored energy in crossovers, and as a result produce a much more pure and natural sound than conventional crossovers.

PARALLEL ELECTRO-MECHANICAL DAMPING

VAF loudspeakers that have multiple woofers have been designed in a way where the geometric relationship between the enclosure panels for the top woofer is different to the geometric relationship of the lower woofer and its associated cabinet panels. The two woofers are then connected together electrically in parrallel enabling the cabinet induced electrical artifacts of one woofer to be electrically damped through the others voice coil.

HYPERSOFT DAMPING

VAF have performed exhaustive testing to find the most effective damping materials. This generation of Hypersoft offers the best performance yet. Accurate placement within each cabinet ensures maximum attenuation of any internal standing waves.

PURE COPPER WOOFER HEAT SINK

The use of a large copper heat-sink inside the voice-coil that projects forward of the cone into the fresh air of the room the speaker is placed in results in two things. Firstly copper is an exceptional conductor of heat, and as such can extract heat from the voice-coil to transfer that heat into the air in front of the cone cooling the voice-coil in the process. Secondly, the mass of the copper is significant and requires a great deal of energy to raise its temperature. As a result the fluctuations in temperature of the voice coil are suppressed.

PURE COPPER DOUBLE INDUCTION RINGS

By employing large pure copper induction rings both in front of and behind the front magnetic pole piece of a woofer or midrange drivers motor, the inductance of the driver becomes far more consistent and distortion levels are reduced 5-10 times lower than conventional speakers.
