Our Kantu loudspeakers are elegant, world-class instruments designed and built in Australia to give you maximum enjoyment when you listen to your music or watch home movies. They cover the full range ofhearing frequencies, from very deep bass to sparkling highs, with very low distortion including flat frequency response, so that they very accurately reproduce the music and other sounds fed into them.
The Kantus were first launched in 1995 making them Legend’s longest running loudspeaker – and for good reason. As described by the Editor of Australian HiFi magazine reviewing the original Kantu 1s “I found them to be very revealing and highly musical loudspeakers. Bass performance was fast and precise …. the midrange makes listening a sheer pleasure …. highs are wonderful and airy….”.
Since this review the Kantus have been subject to continous improvement. Although the outer cabinst shape has remained the same, with its elegant proportions hard to beat, further refinement has been produced by improved internal cabinet bracing, internal profiling and constrained-layer damping. They have also been upgraded form a 2.5 way system to a 3.5 way system by adding a dedicated midrange unit. You can read excellent reviews of the Kantu 4s and Kantu 6s on our review page.
Most importantly significantly improved drivers have become available as materials technology has progressed, leading to improved cone break-up and lower distortion of their sound output. At the heart of the Kantu 9 is the superb 90mm midrange unit also used in our top-of-range Tikandi Grande Bes. It is made from high strength Mg alloy coated on each side with very hard ceramic so that it remains pistonic well above its crossover point. This results in extraordinarily low distortion through the critical midband region allowing these vital frequencies to come through crystal clear and without the hardness or muddle of many loudspeakers in this region.
Its excellent tweeter is made of the same composite material from the same German manufacturer as well – giving the same clarity in the treble. This clarity is maintained by the high quality crossover using polypropylene capacitors (often in parallel to reduce distortion), air-cored inductors and high-power non-inductive wire-wound resistors, all directly soldered to each other – and to the drivers via high quality wire.
The Kantu 9 also has a low-distortion bass unit made from very strong Aluminium alloy. Together with excellent motor and suspension systems, the ensuing low distortion allows the listener to hear tonal structure in bass notes, again resulting in greater realism of the reproduced music – and not just some homogenised version.
With the Kantu 9 we have included the same lens/wave guide as we developed for the Kurre 9. By narrowing the dispersion of the sound waves at the bottom-end of the tweeter’s range the lens enhances its continuity of dispersion with the top-end of the midrange unit at their crossover frequency, so improving the balance of overall sound (direct + indirect) when passing from mid to treble. The lens/waveguide also improves the phase alignment of mid to treble by moving the tweeter back into the baffle so it is in better time alignment with the midrange. Lastly it makes the tweeter less vulnerable to damage – and looks even better!
As shown by the attached measurements, because the Kantu 9s are so accurate with such flat frequency response and low distortion they are very faithful (high ‘fidelity’) and truthful to the music and equipment preceding them in the reproduction chain so will take on the latter’s sound character. If you prefer your music ‘warm or sweet’ then you must partner them with a suitably ‘warm or sweet’ amplifier – perhaps a valve amplifier. Or if you enjoy your music fast & dynamic then choose a suitable fast & dynamic solid-state amplifier. They will work well with relatively low power amps with good current capability but will thrive on more amplifier power.
Given the right preceding equipment you will hear all the emotional drama and nuances of the artists’ playing. Like being there!
