The S25 Speaker Cable 425 is the most powerful model in the series, designed for audiophile setups with high power reserves and long cable runs. The large conductor cross-section and low-inductance multicore design ensure exceptionally low-loss transmission – even under high load or long cable lengths. The sound benefits from a particularly controlled, deep-reaching bass with precise punch, clearly defined mids, and an open, detailed high-frequency reproduction. The spatial presentation is stable and wide. Thanks to high-quality materials such as fine-stranded OFC copper, solid crimp contacts, and gold-plated connectors, the signal remains unaltered along the entire length. Its discreet, functionally elegant design and surprisingly high flexibility despite the large cross-section allow for neat, unobtrusive installation – even in complex rack setups or close to walls.

The S25 Speaker Cable 415 is the versatile solution in the series, impressing both sonically and technically with neutrality, control, and dynamics. The multi-stranded multicore design reduces cable inductance, supporting precise and fast signal transmission. The sound features a defined, powerful bass foundation, cleanly layered mids, and a pleasant openness in the highs – never harsh, but present. The spatial imaging remains stable even at higher volumes. The cable is mechanically robust yet flexible – its unobtrusive jacket and moderate diameter allow for discreet integration into existing hi-fi setups, furniture, or cable ducts.

The S25 Speaker Cable 225 is the compact solution in the S25 series and ideal for small setups. It impresses with solid performance and surprisingly good spatial imaging. The bass remains controlled and precise without bloating, the mids sound focused, voices natural and tangible. The highs are detailed without harshness. Its slim, discreet design combined with high flexibility makes it especially easy to install – whether visibly on open shelves, behind furniture, or in tight cable channels. This allows the Speaker 225 to seamlessly integrate into almost any setup – both acoustically and visually. Click here to discover exciting details
To achieve the best possible sound, it is crucial that the amplifier has the speakers firmly under control. It must drive the Membranes with equal precision and bring them to a controlled stop. One measure of this is the amplifier’s damping factor. It describes how effectively the amplifier can control the speaker. However, the actual damping factor at the speaker is only as good as the weakest link in the signal path. For many speakers, this is the standard bi-wiring bridges—often simple stamped metal plates with poor electrical properties. The in-akustik S25 BiWire Jumpers replace this weak point with a high-quality connection based on the technologies and materials of the S25 cable series. They ensure low-loss and uniform signal distribution between the bi-wiring terminals, thereby supporting more precise control of the speaker cones. The sophisticated multicore structure reduces the skin effect and contributes to a detailed, controlled reproduction. High-purity OFC copper and gold-plated cable lugs minimize contact resistance and ensure a permanently stable connection. Even without true bi-wiring, the S25 BiWire Jumpers offer a high-quality alternative to the standard metal Jumpers found on many speakers.
The S25 Interconnect Cable provides a sonically neutral and technically clean connection for high-quality hi-fi applications. Its highly flexible construction and discreet design ensure easy integration into existing systems. The signal conductors are made of high-purity, oxygen-free copper (OFC) and insulated with foamed polyethylene – a material with an especially low dielectric constant that supports low-loss signal transmission. The symmetrical dual-mono design with separate conductors for positive and negative ensures stable and low-interference signal routing. A dense braid of 186 fine copper strands serves as effective shielding against external interference – such as from Wi-Fi or Bluetooth devices. The gold-plated full-metal connectors provide long-term reliable contact with low transition resistance and high mechanical stability. The cable is manufactured in Germany and each unit is individually tested for signal continuity. Click here to discover exciting details

Phono signals are among the most delicate signals in the entire hi-fi chain: The output levels of MM and MC systems are in the millivolt and microvolt range, respectively — and are correspondingly sensitive to any interference in the signal path. The S25 phono cable is designed precisely for this requirement: It transmits these delicate signals with neutral sound and technical precision—from the record player to the phono stage, without loss, without coloration, and without compromise. At the heart of the S25 phono cable are signal conductors made of high-purity, oxygen-free copper (OFC), insulated with foamed polyethylene—a dielectric with a particularly low dielectric constant for low-loss signal transmission. The balanced dual-mono structure carries the positive and negative signals via separate conductors—this reduces crossover interference and ensures stable, low-noise signal transmission from the record player to the phono preamp. A dense shielding braid made of 186 fine copper wires protects against external interference sources such as Wi-Fi or Bluetooth devices. A separate ground wire reliably dissipates any remaining interference from the record player—for a quiet, hum-free soundstage. The gold-plated solid-metal connectors ensure consistently reliable contact with low contact resistance and high mechanical stability. The highly flexible construction and understated design blend seamlessly into any existing system. Like all cables in the S25 series, the phono cable is manufactured entirely in our cable factory in Ballrechten-Dottingen—assembled by hand and individually tested for flawless signal transmission.
