The Pinnacle of Inakustik’s copper based speaker cable. The LS 4004 AIR.

With the Referenz LS-4004 speaker cable, we continue the incredible story of their Air Helix technology: To achieve perfect air insulation, the new cable uses no less than 16 Cross Link Super Speed waveguides (rather than eight as with the Referenz Air Helix LS 2404). Obviously, the individual conductors themselves play a key role, too. With the LS-4004, too, these are made of 24 high-purity copper wires, each with a razor-thin lacquer coating for extra insulation and braided around a PE core. This design considerably increases stability inside the waveguide by effectively preventing the formation of eddy currents. (These are caused by the very high currents transmitted on the speaker cables – actually the highest ones within the entire audio path.)
AIR HELIX STRUCTURE
In addition, a new clip capable of carrying the increased load of the updated design had to be constructed. This clip not only must bear the surplus weight of the conductors but also needs to ensure flexibility throughout the cable structure. Just like its smaller predecessor, the new clip suspends the helical conductor arrangement freely in the air while keeping the individual conductors at an exact distance throughout the cable. The clips are meticulously assembled by hand at the on-site factory and then threaded into the Cross Link Super Speed waveguide. Finally, the resulting Air Helix receives a highly protective PE network jacket.
A ROCK-SOLID CONSTRUCTION
Between the aluminum splitter and the connectors of the LS-4004, we have implemented ultra flexible parts molded from a special elastomer. These parts are fixed inside the splitter using a specifically designed plastic plug, thus ensuring maximum cable flexibility even in the connector region. Those molded parts extend to the connector front and enclose the inner connector components, thus emphasizing the plain yet charming appearance of the LS-4004. The aluminum splitters are screwed tightly with the first clip in the cable. In summary, this creates a visually appealing and mechanically reliable design – consistent from the connectors on the amplifier side to their counterparts on the speaker side. Using a complex technique, a custom-made machine strips the highly pure Cross Link Super Speed waveguide copper wires from their lacquer coating. Afterwards, the bare wires are bundled up and driven into the onnectors. This procedure prevents the occurrence of contact resistances typical of the use of additional materials such as solder or wire end sleeves.
Any extra material used on a cable (e.g. PVC insulation) causes a degradation of its electrical properties – this is just applied physics. Therefore, Referenz cables feature a PE network jacket implemented using complex techniques. Consequently, the cables are made of just two materials: copper and PE. The LS-4004 AIR is a perfect example of a low-inductance speaker cable: The double-layer multicore design leads to a neutralization of overlapping magnetic fields around the individual conductors. This considerably reduces cable inductance, ensuring that all frequencies are transmitted freely and without any latency. Plus a full range of connector options offers maximum flexibility.
We have opted for tellurium copper as the plug base material rather than brass. This is because tellurium copper offers twice the conductivity. Each plug comprises a basic terminal with a spade or BFA banana adapter laterally threaded to it. This connector design provides maximum flexibility with regard to adjusting the angle between the cable and the connector and also mitigates the effects of mechanical forces acting on both the cable and the connector including their contact interfaces. The connector surfaces are rhodium-coated because this extremely robust material ensures optimum contact even after many mating cycles.

Goods Damaged in Transit.
If any goods arrive damaged, please contact us as soon as possible. Len Wallis Audio will arrange to have the damaged goods returned and either arrange for a replacement of the goods or refund the price to you. Damaged goods must be returned in the condition received by you with all original packaging, accessories and/or manuals.
Refunds will be normally be processed within five (5) days.
Where Len Wallis Audio considers the goods to have breached a consumer guarantee, any shipping costs to return the goods to Len Wallis Audio will be at our cost.
Returns and Repairs.
You may visit Len Wallis Audio and a staff member will assist you with any return or repair. This may include inspecting the goods, arranging for the goods to be repaired, or providing you with a replacement.
Goods must be returned within a reasonable time.
If any goods cannot be easily returned to us due to their size, the fault or because they have been affixed or installed in your premises, please contact us and we will arrange an inspection to assess the goods.
Goods returned for repair will be assessed and/or repaired within a reasonable time. You may be provided with an indicative repair time, which time may vary due to reasons beyond ours or the repairer’s reasonable control, such as part availability and incorrect fault description.
You may be required to pay labour, assessment and/or freight fees, such as where goods are assessed to have been damaged by misuse or accident, or where your rights under the Australian Consumer Law or any manufacturer’s warranty do not apply. We may provide you with an indicative fee, which may vary due to reasons beyond our control.
If any goods that you return are capable of retaining user generated data such as files stored on a hard drive, and songs stored on a portable media player, the replacement or repair of the goods may result in loss of the data. In these circumstances, we recommend you back up data to prevent data loss, and remove sensitive or confidential data, as a party assessing and/or repairing your goods may be required to view data in the course of carrying out the assessment. We will not be responsible for any data loss.
In some circumstances, goods presented for repair may be replaced by refurbished goods of the same type rather than being repaired. Refurbished parts may be used to repair the goods.
Where you have any questions or concerns relating to your Order, please immediately contact us
We understand that sometimes you may simply change your mind about a purchase or have made a wrong selection. In these situations, you have 14 days in which to return your item for a refund, exchange or store credit. If more than 14 days has passed since your purchase we can’t offer you a refund, exchange or store credit.
To be eligible for a return, refund or store credit your item must be in the same condition that you received it. Which is to say, it must be in the original unopened packaging, and in ‘brand new’ saleable condition.
Please note that current Australian Consumer Law does not require us to offer a ‘Change of Mind’ refund. Rather Len Wallis Audio offers 14 day ‘Change of Mind Policy’ in good faith.
