Product information "S25 Jumper | BiWire Jumper"
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 Referenz high-end bi-wire bridge, based on the LS-1002 and the Referenz spade lug KS-60. Concentric copper is used in the conductor structure, where each wire has a precisely defined position within the conductor. This structure ensures even signal transmission for crystal-clear audio reproduction. Under normal conditions, the copper used as conductor material is considered to be one of the next-best electrical conductors after silver. Compared to cheap CCA (Copper Coated Aluminum), copper has a significantly better conductivity and is also mechanically more resilient.
To achieve the best possible sound, it is crucial that the amplifier has a firm grip on the speakers. In addition to activating the membranes to make them vibrate, it must also be able to dampen them effectively. One measure of this is the amplifier’s damping factor. The speakers’ actual damping factor is significantly influenced by the quality of the speaker cables and connecting bridges of the bi-wiring terminals. The original bridges often consist of simple stamped sheet metal parts of inferior quality.
The new in-akustik AIR High End Bi-Wire Jumpers are based on the technologies, findings and materials of the renowned LS-1205 AIR, LS-2405 AIR and LS-4005 AIR speaker cables. If bi-wiring is not an option, these high-end bi-wire jumpers offer an excellent alternative to the often inferior metal bridges on the speaker terminals. They ensure an even and controlled signal distribution, which is perfectly harmonized with the respective speaker cable.

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 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.
