LS-404 Micro AIR
8 concentric conductors. Award-winning value.
The LS-404 Micro AIR uses eight concentric copper conductors arranged in a precisely defined multi-layer pattern with diamond-shaped air chambers for dielectric insulation. Winner of multiple best-buy awards, it delivers an extremely balanced sound character with precise timing and solidly controlled bass — ideal for full-size floorstanding loudspeakers.

Key Features
8-Fold Concentric Architecture
Eight copper conductors in a precisely defined multi-layer pattern create overlapping magnetic fields that neutralise each other, reducing inductance significantly.
Diamond-Shaped Air Chambers
Complex Micro AIR insulation structures form tiny air pockets that increase conductor spacing and reduce capacitance without added bulk.
2 x 10.48 mm Cross-Section
Large conductor area (8 x 2.62 mm per channel) for low resistance and powerful current delivery to demanding speakers.
Rhodium-Coated Connectors
Beryllium copper BFA bananas and brass spade lugs with rhodium coating and spring-loaded contact forks.
Technologies Inside
AIR Technology
Air is the perfect insulator.
Now in its fifth generation, AIR technology uses air as the primary dielectric instead of traditional plastics like PVC. Conductors run freely suspended through the cable via precision-engineered clips at defined intervals, reducing capacitance by approximately 83% compared to standard cables. The Point-to-Point Air Helix architecture extends this principle from connector to connector for almost loss-free signal transmission.
Multicore Architecture
Overlapping fields, lower inductance.
in-akustik's multicore conductor arrangements use four-fold structures where the overlapping magnetic fields of individual conductors deliberately cancel each other out. This reduces inductance and minimises the skin effect at high frequencies, delivering a more neutral, dynamic frequency response.
360 Degree Pressure-Grouted Connectors
Three-axis rotation. 1.5 tonnes of force. Zero solder.
in-akustik's 360-degree BFA banana and spade lug connectors move across three axes, making connection and disconnection effortless while preventing cable stress. Instead of soldering, which introduces additional metal alloys and weak points, each connector is pressure-grouted at 1.5 tonnes of force — creating a gas-tight, vibration-resistant bond. BFA bananas use beryllium copper with solid metal housings, while spade lugs use tellurium copper, both rhodium-coated for lasting conductivity and corrosion resistance.
Micro AIR
Air insulation in a compact, flexible format.
Micro AIR technology creates complex diamond-shaped structures within the cable that form tiny air chambers between the concentric copper conductors. This increases conductor spacing and air content without the physical bulk of full AIR Helix construction, reducing capacitance while maintaining the low resistance and inductance necessary for speaker-level signal transmission. The result is a more compact, flexible cable that brings genuine air-dielectric benefits to a wider range of systems.
