VAF Research I-66 MKII Signature Series Loudspeakers

VAF Signature loudspeakers are the culmination of one of the most intensive electro-acoustic research programs ever undertaken in Australia for consumer loudspeakers. They represent the state-of-the-art in production moving coil loudspeaker technology.

On a slightly smaller scale than VAF’s legendary Signature I-93, the Signature I-66 employs similar design elements and values. Only the best components have been selected, and have been applied with the most sophisticated design techniques currently known. They provide a level of accuracy and performance not seen in any other loudspeaker in the world 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 VAF Signature I-66 is at home in the highest fidelity stereo system.

Uniformity of process across the entire VAF Signature Series also ensures that other VAF Signature Series models can be used in harmony with the VAF Signature I-66 to form a multi-channel surround sound theatre systems without peer.

Description
The Signature I-66 speaker is beautifully crafted to the highest standard in finely finished genuine timber veneers and weigh in at an impressive 60kg.

Featuring a time-aligned partially vertically symmetrical driver array, the VAF Signature I-66 is a large, floor standing four driver, three way speaker. Each cabinet contains one 210mm woofer and two 130mm magnesium alloy cone midrange drivers symmetrically arrayed about a single 25mm double chamber Sonotex dome tweeter.

Each woofer cone is constructed of composite hard paper pulp embedded with carbon and Kevlar fibres which are individually treated with an anti-resonant natural fibre. Each midrange cone is precisely and individually machined from forged magnesium alloy for the most detailed resolution and midrange performance of any loudspeaker driver manufactured.

The woofer and the midrange drivers have low distortion, long linear throw motor systems employing massive solid copper double shorting rings, both in front and behind their front magnetic pole plates, and have solid copper phase correction plugs 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 Sonotex dome backed by it's own anti-resonant acoustic chamber.

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.

Optimised internal damping is provided by VAF’s advanced HyperSoft material, to effectively eliminate internal cabinet reflections and standing waves.

An obvious and integral design feature on every VAF loudspeaker is natural, acoustically absorbent fibre pads which are fitted around each tweeter and midrange driver to accurately control dispersion and effectively eliminate diffraction effects.

Manufactured from only first grade MDF up to 44mm thick, cabinet construction is highly detailed. Precisely mitred joints and substantial internal cross-bracing characterise the superior quality of these loudspeakers. Finishes include very 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 additional cost. Other finishes are available on request.
