Inakustik LS-2404 Air BFA 45° Speaker Cable - Open Box

The Inakustik LS-2405 AIR is the result of several years of research and development in the field of audio cables. This speaker cable from the Reference series uses air-based technology as its primary dielectric, contributing to high-quality sound reproduction. Made in Germany with carefully selected materials, the LS-2405 AIR delivers a precise and detailed listening experience.

Air Helix technology: the heart of innovation

At the heart of the LS-2405 AIR lies Inakustik's patented Air Helix technology. This unique approach uses air as the primary dielectric, minimizing capacitance and dielectric losses to an unprecedented level. The helical structure guides the conductors through the cable in a "floating" manner, achieving an air gap of nearly 100% between the signal conductors.

This architecture is held together by specially developed clips, creating a flexible yet stable frame that preserves optimal signal integrity along the entire length of the cable. The use of air as a dielectric significantly reduces the negative effects of traditional insulating materials on audio signal transmission.

The new generation LS-2405 AIR introduces the Air Helix point-to-point construction. This advancement ensures a seamless transition in the connectors, maintaining the Air Helix architecture from one end of the cable to the other. The result is a further reduction in signal loss, improving detail reproduction and dynamic performance to unprecedented levels.

Multi-strand structure: for optimal signal transmission

The LS-2405 AIR employs an ingenious multi-strand structure that significantly reduces inductance, a critical parameter for speaker cables. The clever arrangement of conductors in interlocking multi-strand structures creates overlapping areas of magnetic fields, thus noticeably decreasing inductance.

This design allows for unimpeded transmission of the entire frequency spectrum, including high frequencies and dynamic pulse sequences, without any time delay. The result is a more detailed sound with refined and precise dynamics. Every detail is reproduced accurately and harmoniously, offering an exceptionally rich soundstage.

The cable also utilizes a Cross Link Super Speed waveguide, designed to combat skinning effects caused by eddy currents in the conductor. This braided structure ensures precise transmission of even the most extreme current peaks, resulting in a balanced soundstage with vibrant timbres across all frequencies.

Materials and manufacturing: German excellence

Inakustik has made no compromises on the quality of materials used for the LS-2405 AIR. The conductors are made of high-purity OFC (Oxygen-Free Copper), carefully selected and drawn to precise specifications. This attention to material quality contributes significantly to the cable's low noise floor and exceptional signal transmission properties.

Each LS-2405 AIR cable is a testament to Inakustik's commitment to excellence. Handcrafted in Germany by skilled technicians, each cable undergoes rigorous quality control at every stage of production. The result is a product that not only meets the expectations of the most discerning audiophiles, but often exceeds them.

The PE-reinforced outer sheath provides robust protection while maintaining the flexibility needed for easy installation. Despite its large 24 mm diameter, the cable remains flexible enough to adapt to most audio system configurations.

Revolutionary connectors: easy installation and optimal contact

The LS-2405 AIR also stands out thanks to its innovative connectors. The BFA banana plugs and fork terminals are 360° rotatable, an innovation developed in-house by Inakustik to facilitate connection and ensure optimal contact with the amplifier and speaker terminals.

The connectors are made of beryllium copper for the BFA banana plugs and tellurium copper for the lugs, offering excellent conductivity. Rhodium plating ensures long-lasting corrosion resistance and maintains contact quality over time.

The connectors are assembled by crimping under a pressure of 1.5 tons directly onto the conductive material of the cable. This technique eliminates the need for soldering, a potential source of contact resistance, and ensures a stable, low-resistance connection.

Evolution compared to the LS-2404 AIR: key improvements

The LS-2405 AIR represents a significant evolution compared to its predecessor, the LS-2404 AIR. The main improvement lies in the Air Helix point-to-point technology, which now extends the Air Helix structure to the connectors. This advancement allows for a smoother signal transition, further reducing losses and improving transmission accuracy.

The new 360° rotatable connectors are another major improvement, offering increased flexibility during installation and ensuring optimal contact with the terminals of audio equipment.

These technical refinements transform the already exceptional AIR cables into true masterpieces of audio engineering, pushing the boundaries of sonic fidelity even further.

Listening experience: what audiophiles say

Audiophile and specialist critic reviews are unanimous: the LS-2405 AIR offers an audible improvement in sound quality. Users report increased clarity, a more precise stereo image, and a more natural reproduction of timbres.

Many note that the LS-2405 AIR allows speakers to acoustically "disappear," creating a more immersive and three-dimensional soundstage. The cable's ability to transmit micro-details and dynamic nuances is particularly praised, adding a new dimension to familiar recordings.

Audiophiles also highlight the tonal balance of the cable, which does not seem to color or alter the signal, but rather reveals the true nature of the recording and the audio system.

Practical considerations: installation and compatibility

Despite its exceptional performance, the LS-2405 AIR remains a practical cable to install and use. Its flexibility, despite its large diameter, allows for installation in most configurations. The swiveling connectors facilitate connection, even in confined spaces.

The cable is compatible with a wide range of high-end audio equipment. However, to fully utilize its capabilities, it is recommended to use it with components of equivalent quality.

It is important to note that the LS-2405 AIR, due to its advanced technology and build quality, represents a significant investment. It is particularly well-suited to high-end audio systems where every component in the audio chain is optimized for maximum performance.
