Inakustik Exz S25 Speaker 425 2x3,0m BFA SBW
- Multicore structure: minimizes inductance, preserves details
- Tight bass control with precise punch
- OFC copper & gold-plated connectors for minimal transmission loss
- Elegant design, high flexibility despite large cross-section
- Conductor cross-section: 2 x 5.0 mm²
The S25 Speaker 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.
Manufacturing quality for entry into high-end
The S25 series was developed as an entry point into the world of high-end hi-fi – 100% made in Germany. Each cable is produced in our in-house workshop: carefully handcrafted, individually tested, and technically refined down to the last detail. We invest in high-quality materials, solid expertise, and genuine craftsmanship – not in glossy wrapping or excessive packaging. The sturdy cardboard packaging protects what matters most: your listening experience. Because sound doesn’t come from appearances, but from quality – honest, direct, and authentic.
Every cable a promise: Quality assurance in the S25 series
Before any cable from the S25 series leaves our manufacturing facility, 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 at the entry level of high-end hi-fi, every detail matters.
OFC Copper: Pure Material for Pure Music
For the S25 audio cables, we use only highly pure, oxygen-free copper (OFC) with a purity level of at least 99.95%. This material offers excellent conductivity and reduces contact losses – even over longer cable runs. Additionally, OFC copper is especially resistant to corrosion, ensuring sonic stability over the years. Combined with the foamed PE dielectric and dense shielding, the signal remains unaltered – from the source to the amplifier. The S25 cables deliver music with high clarity and authentic dynamics – honest, direct, and without artificial coloration.
Dense Shielding & Floating Shield
Especially for RCA audio cables, high-quality shielding is crucial to protect the sensitive signal from interference caused by Wi-Fi, Bluetooth, or power supplies. The S25 series relies on a tightly woven high-density copper braid and a so-called floating shield: the shielding is electrically separated from the signal and directs interference away without acting as a source of noise itself. This keeps the audio signal free from hum, noise, and high-frequency interference – even in demanding home environments. The result is a clean, interference-free transmission with maximum detail accuracy.
