Amphion Argon3LX white (pack of 2)

The Amphion Argon3LX is a compact floor-standing speaker derived from the Argon3LS model. It features a new generation titanium tweeter, a redesigned crossover filter, and a passive radiator, a characteristic technology of the brand. This model builds on the experience gained by the Finnish manufacturer since 1998 and is designed to adapt to different listening environments.

A new generation tweeter with mastered design

The Argon3LX introduces a major evolution with its new 1-inch titanium tweeter, specially developed for this X series. This driver significantly improves high-frequency response compared to the previous model, offering a striking level of detail and clarity. The titanium dome, a material favored for its rigidity and lightness, ensures precise reproduction up to 55 kHz, well beyond human perception capabilities.

This tweeter integrates into Amphion’s exclusive waveguide, now in its fifth generation. This U/D/D (Uniformly Directive Diffusion) technology solves several fundamental acoustic challenges: it physically aligns the acoustic centers of the tweeter and mid-bass driver, uniformizes dispersion across a wide frequency band, and minimizes cabinet diffractions. The waveguide, made from a carefully selected high-density material, features a smooth curve that controls directivity without creating unwanted colorations.

The 6.5-inch aluminum woofer handles midrange and bass reproduction with a rigid yet lightweight membrane, capable of perfectly controlled pistonic motion within its passband. This driver, supplied by SEAS in Norway, benefits from specific treatment for Amphion that optimizes its mechanical characteristics. The combination with the tweeter occurs at 1,600 Hz, an unusually low crossover point that presents several decisive advantages.

A unique approach to filtering and transducers

The revised crossover of the Argon3LX constitutes one of the major improvements of this new generation. Amphion maintains its philosophy of electrical simplicity, using high-quality components in minimal numbers to preserve signal transparency. The 1,600 Hz filtering, well below the critical human hearing zone (2-5 kHz), ensures particularly coherent integration between the two transducers.

This low crossover frequency allows the tweeter to reproduce only the frequencies where it excels, while the mid-bass driver handles the essential vocal and instrumental spectrum that is critical. The result: a quasi-point source in the most sensitive zone of our hearing, creating a stereophonic image of remarkable precision with exemplary phase coherence.

The rear passive radiator advantageously replaces a traditional bass-reflex port. This driverless membrane, precisely tuned by a calibrated mass, moves in perfect synchronization with the front woofer. This solution eliminates turbulence and parasitic noise associated with ports, while allowing placement close to walls without compromising tonal balance. The bass gains definition and control, extending down to 30 Hz (-6 dB) with remarkable articulation.

The high-density MDF cabinet uses thick panel assembly with strategically placed internal bracing. A perforated plate behind the mid-bass driver, developed in collaboration with a Swiss university, controls internal airflow and stiffens the structure. This massive construction of 21 kg per speaker guarantees a complete absence of parasitic vibrations, even at high volume.

Installation versatility and consistent performance

The Argon3LX stands out for its ability to maintain its sonic qualities in various listening conditions. The controlled dispersion technology allows for an enlarged listening zone: multiple listeners can simultaneously enjoy a coherent stereophonic image, without being limited to a single listening position. This characteristic, inherited from Amphion professional monitors, radically transforms the collective listening experience.

The passive radiator offers remarkable placement flexibility. Unlike bass-reflex speakers that require significant clearance, the Argon3LX can be positioned just a few dozen centimeters from the rear wall without bass bloat. This placement tolerance greatly facilitates integration into real living spaces, where layout constraints often impose acoustic compromises.

The 85 dB sensitivity and 8-ohm nominal impedance make the speaker compatible with a wide range of amplifiers, from 50 to 250 watts. However, the exceptional transparency of the Argon3LX ruthlessly reveals the quality of associated electronics. A quality amplifier with good current reserves will allow full exploitation of the dynamic potential and resolution finesse of these floor-standing speakers.

The internal wiring uses silver-plated pure copper, while the binding posts accept all types of connectors. The supplied base improves stability and effectively decouples the speaker from the floor via eight stainless steel spikes. The compact dimensions (995 x 234 x 344 mm with base) facilitate integration into medium-sized rooms while offering the physical and sonic presence of a true floor-standing speaker.
