Amphion Argon3X Bookshelf Speaker [Pair]

Product Concept

The Amphion Argon3X inherits the natural sound imaging and manageable size of the Argon3S, while as a new generation X-Series, it further enhances resolution, bandwidth, and spatial expression as a bookshelf speaker.

With the newly designed titanium tweeter and revised crossover, concepts introduced in the higher-end Krypton3X, the extension of high frequencies, subtle nuances, decay of sound, and integration between drivers have all improved. If the Argon3S is a high-quality standard model, the Argon3X is an advanced model that further refines that expressive capability.

Rather than emphasizing sound in a flashy way, it allows you to perceive the information within the recording more deeply and quietly. The evolution of the Argon3X is not just a specs upgrade but aimed at naturally drawing out the depth of music and performance nuances.

The appeal of the Argon3S, even more precisely

Argon3X raises the depth of the sound field, clarity of localization, and reproduction of reverberation one step higher while maintaining the same size as the Argon3S. The position of vocals floating between speakers, the sense of distance between instruments, and the spatial atmosphere of the recording become easier to perceive, allowing for a natural understanding of the structure of the music.

In particular, with acoustic instruments, vocals, chamber music, jazz, and live recordings, differences are noticeable in the expression of the attack and decay of sounds. Argon3X's charm lies in making fine details naturally emerge within the flow of the performance, rather than bringing them forward excessively.

Newly designed titanium tweeter enabling high-frequency reproduction up to 55kHz

Argon3X adopts a newly designed 1-inch titanium tweeter. The high frequencies extend up to 55kHz, delicately rendering the harmonics of cymbals, bowed strings, breath of vocals, and the reverberation of the hall, capturing the subtle expressions of music.

Although the high frequencies are extended, it is not a speaker that relies only on brightness or intensity. Rather, it evolves in a direction that carefully presents the contours of sound, spatial openness, and gradations of reverberation. The sound field is wide, the localization clear, and it creates a natural stage that does not make the speaker’s presence noticeable.

Improved crossover for cohesiveness

The crossover frequency is 1,600Hz. Emphasis is placed on the connection between the tweeter and the 6.5-inch aluminum woofer, smoothly reproducing important vocal and instrumental bands.

In Argon3X, reviewing the crossover further enhances the balance and cohesiveness between drivers. The contours of each instrument are clear, yet the music as a whole is not fragmented. Vocals naturally come forward, instruments maintain appropriate distances, and the depth of the recording space is easier to perceive.

5th generation waveguide and natural sound field formation

Amphion’s unique waveguide is an essential technology for aligning the tweeter’s radiation characteristics and naturally connecting it to the woofer. In Argon3X, combined with a lower crossover point, it achieves both sound coherence, clear localization, and a wide listening area.

Not only when listened to directly in front of the speakers, but also in situations where you slightly change your position in the living room, the sound image remains stable, allowing you to enjoy music and movies in a natural balance. Here lies the Amphion characteristic of being accurate without being overly fussy, making it easy to handle.

Low-frequency texture beyond bookshelf types

The Argon3X, with its 6.5-inch aluminum woofer and rear-mounted passive radiator, reproduces deeply controlled low frequencies despite being a bookshelf type. The low frequencies are not pushed by volume but are rendered with accuracy in pitch, speed, and contour.

The bassline does not become unclear, the kick drum does not lag, and the low notes of the piano and cello do not muddy the midrange. While stabilizing the foundation of the music, it is balanced so as not to compromise the high resolution and transparency that the Argon3X offers.

A speaker that honestly reflects the quality of the amplifier

The Argon3X has a wide recommended amplifier output range of 50–250W and faithfully reflects the quality of the amplifier it is paired with. This does not mean that a high-power amplifier is necessary; rather, by pairing it with an amplifier that excels in control, quietness, and sound staging, a higher level of performance can be achieved.

It is possible to enjoy natural midrange with a tube amplifier, or to enhance speed and control with a transistor amplifier. However, the Argon3X tends to honestly reveal the character of recordings and equipment, making it a speaker whose expression can easily change depending on the pairing.

Choosing between Argon3S and Argon3X

The Argon3S is a classic model that provides a well-balanced Amphion-like natural soundstage, clear midrange, and easy-to-handle low frequencies. On the other hand, the Argon3X elevates this approach to higher resolution, wider range, and precise spatial expression.

The Argon3S is suitable for those who want to enjoy music naturally over a long period. The Argon3X is suited for those who want to perceive finer nuances, reverberations, and the depth of the recording space. Although installation is similar for both, when aiming for a higher ceiling in expressive capability, the Argon3X is an extremely attractive choice.

Evaluation in Overseas Reviews

The Argon3X is reviewed in the UK audio magazine hi-fi+ as the next-generation bookshelf speaker succeeding the Argon3S. The review notes that the Argon3S already had the level of completeness that could be called a reference in its price range, and the Argon3X is evaluated as a model that has evolved even further from that.

Technically, special attention is given to the newly designed titanium tweeter and the significantly revised crossover. The high-frequency characteristics of the Argon3X have been extended from 25kHz on the previous Argon3S to 55kHz, reproducing reverberation, harmonics, and a sense of space over a wider range. Additionally, the series crossover design ensures the connection between drivers, coherence of sound, and stability of the load seen by the amplifier.

In terms of sound quality, the depth of the soundstage and three-dimensional imaging are highly praised. The review mentions its ability to clearly organize the movements of individual parts in an orchestra and complex musical structures, presenting it not just as a high-resolution speaker but as one that naturally conveys the structure of the music and the intention of the performance.

Regarding the bass, the rear-mounted 6.5-inch aluminum passive radiator provides controlled reproduction differing from a bass-reflex design. Instead of excessively boosting low frequencies, it maintains contour, timing, and texture, making it easier to place near walls, which is characteristic of Amphion's design.

According to hi-fi+, although the Argon3X is not a model aimed at the absolute scale or mass like large speakers, it is highly praised for its level of completion in other aspects. While maintaining the convenience of a bookshelf design, it significantly enhances resolution, soundstage, and musical clarity, making it a top-tier, highly refined model within the Argon series.
