Amphion Krypton3X - Floorstanding Speakers

The new and updated Amphion Krypton3X is a reference project 25 years in the making. This innovative and unique three-way reference loudspeaker allows you to enjoy full range, realistic orchestral performances without owning a concert hall.

Amphion's flagship houses innovative technologies, which ensure the highest level of performance, even in less than optimal listening environments.

Technologies

The Krypton’s three-way design configuration is two midranges or mid/woofers (two proprietary paper/papyrus midrange drivers combining wood and cane) in a cardioid enclosure (for control of dispersion of the speaker) placed vertically above and below the (titanium) tweeter, and operating in parallel to implement a three-way crossover.

This geometric arrangement of the drivers eliminates lobing error; is independent of inter-driver phase relationships; has no effect on crossover selection; eliminates off-axis nulls; and provides another polar response when the drivers are not driven in phase.

The Krypton’s design incorporates a technology called U/D/D - Uniformly Directive Diffusion. U/D/D helps speakers keep their clarity and naturalness, even when placed close to boundaries - be there walls, bookshelves or desktops.

What is a Waveguide?

A waveguide is a generic term to describe a structure that guides waves with minimal loss of energy by restricting their expansion to one or two dimensions. A loudspeaker’s diaphragm coupled directly to ambient air is a poor impedance match. Amphion speakers are recognised for their use of tweeter waveguides in front of the driver to control the speaker’s directionality.

Features

1. The highly innovative cardioid midrange allows Kryptons to perform well even in small rooms, close to big windows, and under other acoustic irregularities which traditional speakers cannot cope with. Both midrange drivers work in their own chambers, side vented by holes drilled in the shape of an acute triangle.
2. Krypton’s proprietary paper-papyrus 8” (203mm) midrange is actually many drivers in one and due to careful driver placement, and together with the tweeter, forms a perfect time-accurate point source which works from 160 Hz and upwards. Inside the critical 600-2000 Hz hearing-range, the cone’s “ribs” transform the unit to work similarly to 4“ (102mm), which leads to air and nuances, but will take full advantage of low distortion and high power handling of the 8” units.
3. The midrange clarity coupled with the power which can be achieved by the Krypton’s two corrugated 8” units working in unison makes you wonder how you ever could live with the 6.5” (165mm) other manufacturers offer at this price point.
4. Krypton reduces unwanted sound reflections from both the side and back-walls (by up to 20 dB).
5. Krypton’s 10” (254mm) woofer has an aluminum diaphragm, thick rubber front suspension, and a large double magnet. It is mounted on the side of the cabinet so that the speakers can be positioned with the woofers facing either inside (standard room placement) or outside (for a broader soundstage). The woofer is mounted into a vented enclosure with the vent itself located between the midrange drivers’ chambers.
