Powerful Sound Without Loss:

The S25 Speaker 425 is the flagship model in the S25 series, developed for audiophile systems where both power reserves and cable length matter. Its large conductor cross-section and low inductance ensure exceptionally low signal loss, even under heavy load or long distances. The result is a precise and controlled bass, well-defined midrange, and open, detailed treble. The wide and stable soundstage delivers an impressively realistic listening experience, even during complex musical passages.

Multicore Technology for Maximum Control:

The advanced multicore construction consists of several fine-stranded conductors running in parallel to reduce inductance and preserve signal integrity. The symmetrical layout minimizes electromagnetic interference, providing more accurate transients, faster response, and a broader dynamic range. This means more control, more precision, and more music in every tone.

Pure Copper, Pure Sound:

Only the best materials are used in the S25 series - 99.95% pure oxygen-free copper (OFC). This high purity ensures optimal conductivity and minimal resistance, significantly reducing loss and distortion. Combined with PE insulation and gold-plated connectors, the signal remains unaltered from amplifier to speaker. The result is natural, clear, and authentic sound reproduction without coloration.

Perfect Connections with Crimp Technology:

Every connection in the S25 series uses professional crimp technology, where conductors are gas-tight pressed under high pressure. This eliminates corrosion risk and ensures long-term contact stability. The gold-plated connectors guarantee low contact resistance and consistent signal transmission, even after frequent connections. The result is a cable that lasts – delivering the same pristine sound quality year after year.

German Quality and Craftsmanship:

The S25 series is 100% made in Germany, focusing on precision and quality. Each cable undergoes individual testing for continuity and flawless functionality before leaving production. Instead of excessive packaging or flashy details, you get pure sound and genuine craftsmanship. It’s your entry into high-end sound – honest, direct, and authentic.
