Building on the development of the i25 and the i35, the floor standing i45 extends the performance of the new compact Signature series with SEAS Magnesium/Alloy drive units and in a refined big sounding but physically compact three way speaker.

Deeper extended bass from the SEAS aluminium woofer providing a rich and more full bodied experience. Another SEAS Excel dedicated mid range and tweeter in an advanced coaxial design couples to the bass seamlessly. The coaxial design places the high frequency driver perfectly in the acoustic centre of the surrounding midrange driver. This means perfect uniformity of sound, perfect alignment of the high frequency range with the midrange frequencies which results in accurate, detailed sound over a wide area in your home.

The Signature i45 provides impact and performance. The three way design separates out the more demanding low frequencies to the matching specially designed long throw, highly dynamic 6 1/2" woofer. The coaxial midrange driver is left to accurately handle the detail and finesse required for clean and clear reproduction over that frequency band. Vocals, instruments like piano, guitar, violin can be reproduced with amazing clarity.

The reproduction accuracy is superb - transparency, detail, imaging, and sound staging deliver an amazingly life-like performance. The accuracy and dynamic capability contribute significantly to its realistic reproduction of all musical genres. The bass performance is extended and dynamic. Extended to 30Hz, this compact speaker sounds more like a well resolved larger floor standing speaker.

Uniformity of process across the entire VAF Signature Series ensures that other VAF Signature models can be used in harmony with the VAF Signature i45. In a multi channel home theatre system for example, paired with the Signature i90's in the rear channels or i25's both rear and centre channel.

Manufactured from only first grade MDF up to 43mm thick, cabinet construction is highly detailed. Precisely mitred joints and substantial internal cross-bracing characterise the superior quality of these loudspeakers.

Years of experience lay behind the design of this unique speaker range. Made by hand in our Adelaide manufacturing facility, every one is taken through an extensive build process only begun when you order. Your speaker uniquely made for you.

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.


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.


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.


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.


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.
