VAF Signature i93 MKIII SE Floorstanding Speakers - Trade In

Traded in pair of VAF Signature i93 MKIII SE's in Black Oak timber finish. Cabinets in excellent condition. These speakers were upgraded by us to SE spec before the customer traded up to MKV - so the SE crossovers, SEAS beryllium tweeters and internal Analysis Plus cabling are brand new. Speakers fully tested with 5 year warranty. Price includes shipping nationwide (to metro areas). 

THE SE VERSION

The VAF Signature i93 MKIII SE. The flagship of our range, and one of the finest and best sounding loudspeakers ever to come out of Australia, if not the world.

The loudspeaker that is responsible for the famous quote from Rolling Stone Magazine – ‘The ultimate in high fidelity performance with the best bass in the world’.

It was developed in the mid-late 90’s when our founder Philip Vafiadis set out to build a loudspeaker with the most accurate, clean and most pure performance that had ever been developed. Utilising very high quality drivers from SEAS Norway, along with the most advanced crossover techniques, hand built in imposing, finely crafted locally built timber cabinets, the result far surpassed anything that had been produced in Australia up until that time and very quickly gained a cult following. It was so good that Sony and Philips requested to use our Signature i93 speakers for the public Australian launch of the SACD format at the Sydney Opera House.

More than 20 years later and the Signature i93, now in its third generation, still stands tall amongst its peers and continues to wow every customer who listens.

The SE version for the i93 MKIII is something very special. We've gone all out including matched super refined high speed Beryllium tweeters, high speed capacitors in the critical signal paths, silver soldered terminations, mass damping of the cabinets and heavy gauge high quality Analysis Plus internal cabling.

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 aligned.

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 overall response of the speaker. VAF use a particular type of design approach which minimises the unnecessary 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 parallel enabling the cabinet induced electrical artifacts of one woofer to be electrically damped through the other's 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.
