Inakustik S25 Speaker 225 Speaker-Cable - Single-Wire
Features
The S25 Speaker 225 is the compact solution of the S25 series and ideal for compact setups. It impresses with its solid performance and astonishingly good spatial imaging. The bass remains controlled and precise without over-emphasizing, the mids sound focused, and vocals are natural and tangible. The highs are differentiated without harshness. Its slim, unobtrusive design combined with its high flexibility makes it particularly easy to install – whether visible on open shelves, behind furniture, or in tight cable ducts. This allows the Speaker 225 to be seamlessly integrated into almost any setup – both acoustically and visually.
Sound doesn't just originate at the speaker.
Speaker cables are far more than mere wires connecting the amplifier and the speaker – they help determine how much of the music actually reaches you. Every cable acts electrically like a filter composed of resistance, inductance, and capacitance. These properties influence whether details are preserved or whether highs lose brilliance and bass loses precision. Especially with speaker cables, conductor cross-section, copper quality, and construction are crucial for low-loss, dynamic signal transmission. The S25 series uses high-purity OFC copper, sophisticated multicore designs, and flexible, robust materials. This keeps the music signal clear, true to its impulses, and authentic – allowing you to hear what's truly on the recording. A good cable doesn't color, but transmits: It is the stable bridge between your components and the musical expression.
Multicore Technology: More Control, More Sound
A technical core of the S25 speaker cables is their multicore construction. Unlike traditional conductors, several finely stranded individual conductors run parallel to each other – this reduces cable inductance, improves high-frequency characteristics, and preserves the signal structure even during fast transients. The symmetrical distribution of the conductors also minimizes interference, as magnetic fields partially cancel each other out. This is particularly evident in the Speaker 415 and 425 models, resulting in tight, contoured bass reproduction, precise soundstage imaging, and brilliant detail resolution in the high frequencies. The result: high impulse fidelity, more control, and a spatial sound that doesn't get lost – even during complex passages.
FC Copper: Pure Material for Pure Music
For the S25 series, we use only high-purity, oxygen-free copper (OFC) with a purity of at least 99.95%. This material offers excellent electrical conductivity and reduces transition losses – even over long cable runs or with high current flow. OFC copper is also particularly resistant to corrosion, ensuring sonic stability for years. Combined with high-quality insulation materials and gold-plated connectors, the signal remains unaltered – from the amplifier output to the speaker terminal. The S25 cables transmit music with high audibility and authentic dynamics – honest, direct, and without artificial coloration.
Crimping Technology & Gold-Plated Contacts
Connectors are critical points in any signal path – they determine whether sound quality remains consistent. The S25 series uses professional crimping technology: Fine-stranded copper conductors are compressed under high pressure to create a gas-tight seal, effectively preventing corrosion and ensuring long-term contact stability. Gold-plated connectors ensure consistently low contact resistance and are resistant to oxidation – even with frequent reconnection. This combination guarantees a reliable, sonically clean connection that neither loses detail nor slows down dynamics. For lasting sound fidelity – completely maintenance-free.
Every cable is a promise: Quality assurance for the S25 series
Before each S25 series cable leaves our factory, it is individually tested for complete signal continuity. This ensures that every connection, from the plug to the conductor, functions flawlessly. This final inspection is part of our uncompromising commitment to quality – because even when entering the world of high-end hi-fi, every detail counts.
Manufactured quality for entry into high-end hi-fi
The S25 series was developed as an entry into the world of high-end hi-fi – 100% Made in Germany. Each cable is created in our in-house factory: carefully handcrafted, individually tested, and technically sophisticated down to the last detail. We invest in high-quality materials, in-depth know-how, and genuine craftsmanship – not in glossy foil or exaggerated packaging. The robust cardboard packaging protects what matters most: your listening experience. Because sound isn't created by appearances, but by quality – honest, direct, and authentic.
