The S25 Speaker 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.

Sound doesn't start at the speaker

Speaker cables are much more than just wires between the amplifier and the speaker – they help determine how much of the music actually reaches you. Electrically, every cable acts like a filter made up of resistance, inductance, and capacitance. These properties influence whether details are preserved or whether highs lose brilliance and bass loses precision. Especially for speaker cables, conductor cross-section, copper quality, and construction are crucial for low-loss, dynamic signal transmission. The S25 series relies on high-purity OFC copper, thoughtful multicore designs, and flexible, durable materials. This keeps the music signal clear, true to impulse, and authentic – so you hear what’s really on the recording. A good cable doesn’t color the sound, it transmits it: It is the stable bridge between your components and musical expression.

Multicore technology: More control, more sound

A technical core feature of the S25 speaker cables is their multicore construction. Unlike conventional conductors, several fine-stranded individual wires 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 helps minimize interference, as magnetic fields partially cancel out. This is especially evident in the Speaker 415 and 425 models, resulting in tight, well-defined bass reproduction, precise soundstage imaging, and brilliant high-frequency detail resolution. The result: high impulse fidelity, greater control, and spatial sound that remains stable – even during complex passages.

OFC copper: Pure material for pure music

For the S25 series, we use only high-purity, oxygen-free copper (OFC) with a purity level of at least 99.95%. This material offers excellent electrical conductivity and reduces transmission losses – even over long cable runs or with high current flow. OFC copper is also highly resistant to corrosion, ensuring long-term sound stability. Combined with high-quality insulation materials and gold-plated connectors, the signal remains unaltered – from the amplifier output to the speaker terminals. S25 cables deliver music with high transparency and authentic dynamics – honest, direct, and without artificial coloration.

Crimp technology & gold-plated contacts

Connector joints are critical points in any signal path – they determine whether sound quality remains consistent. The S25 series uses professional crimp technology: fine-stranded copper conductors are gas-tight pressed under high pressure, effectively preventing corrosion and ensuring lasting contact stability. Gold-plated plugs provide consistently low contact resistance and are resistant to oxidation – even with frequent plugging and unplugging. This combination guarantees a reliable, sonically clean connection that neither swallows details nor slows down dynamics. For lasting sound fidelity – completely maintenance-free.
