Wireworld - Equinox Biwire Speaker Cable Jumpers

Six-inch OCC-7N copper links to replace the stamped metal straps your speakers came with — the single cheapest worthwhile upgrade to a bi-wirable speaker.

If your speakers have two pairs of binding posts, they shipped with a pair of stamped metal plates bridging them. Those plates cost the speaker manufacturer pennies and they are the only part of the signal path between your amplifier and your tweeter that nobody thought about. Everything you spend on speaker cable runs through them.

Jumper links replace them with actual cable. These are Equinox specification: OCC-7N copper — the Ohno-cast, seven-nines material — in a Tri DNA Helix with three conductors and sixteen insulated strands, 18AWG, insulated with Composilex 5, terminated on silver-clad OFC Uni-Term contacts. Six inches long.

It is the least glamorous purchase in the shop and one of the more sensible ones. You are not adding anything; you are removing a bottleneck you paid for by accident.

Spade-to-spade and banana-to-banana are the terminations we list; Wireworld also makes mixed combinations, so ask if you need spade one end and banana the other.

One thing to check with us before you order. Wireworld currently sells the Equinox jumpers as a pack of four, which is what a stereo pair of bi-wirable speakers needs — two links per cabinet. Their current pack is the Series 10 version. Our listing predates that, and we would rather confirm the pack count and generation of the specific stock we hold than have you open the box and find two when you needed four. Ask us and we will look.

Specifications

• Type: Bi-wire jumper links for speakers with two pairs of binding posts
• What they do: Replace the stamped metal shorting straps that come fitted to bi-wirable speakers. Those straps are the cheapest component in the entire signal path and every watt reaching your tweeter passes through them
• Conductor material: OCC-7N Copper
• Geometry: Tri DNA Helix — 3 conductors, 16 insulated strands. Wireworld’s DNA Helix uses flat, ribbon-like conductor strands layered in parallel groups, instead of round strands twisted together as in ordinary cable. Their stated aim is to reduce the eddy-current losses they attribute to conventional stranded and solid conductors. Moving up a generation or a tier generally means more strand groups.
• Gauge: 18AWG (0.8 sq mm)
• Insulation: COMPOSILEX 5. Composilex is Wireworld’s composite insulation, and its stated purpose is reducing triboelectric noise — the small static charges that build and discharge where a conductor rubs against its insulation as the cable moves or vibrates. That effect is real and well known in cable design. Wireworld’s specific claim that Composilex 5 beats every other low-loss insulation including Teflon is published without any supporting measurement.
• Contacts: Silver-clad OFC Uni-Term
• Length: 6 inches. This is the only length Wireworld publishes
• Terminations offered: Spade to spade and banana to banana here. Wireworld also makes spade-to-banana and banana-to-spade — ask us
• Pack count: Confirm with us before ordering. Wireworld’s current Equinox jumper is sold as a pack of four, which is what a stereo pair of bi-wirable speakers needs. This listing predates that pack and we would rather check the count and generation of the stock we actually hold than guess
• Electrical figures: None published. Wireworld does not publish capacitance, inductance or resistance per unit length for this cable, or for any cable in the range as far as we could find. Their claims about noise and resolution are assertions rather than measurements — no test method, no figures, no independent results are given. The one objectively checkable technical claim behind the range is the DNA Helix patents, US 8,569,627 and US 9,620,262, and a patent establishes novelty rather than performance. We would rather tell you that than quote marketing copy at you as though it had been measured.
• Country of manufacture: Not published. Wireworld is headquartered in Davie, Florida, but we could find no Made in USA claim for the cables themselves anywhere on their site — the only manufacturing statement we found concerns packaging, which they say is printed in the US. A head office is not a factory and we are not going to present it as one.
• Warranty: Wireworld publishes a Limited Lifetime Warranty against manufacturing defects to the original purchaser, with damage from abuse or wear excluded. That is essentially the whole published policy — there is no itemised exclusions list, no claims procedure and no statement about transferability, though the phrase “to the original purchaser” implies it does not transfer. Proof of purchase from an authorised dealer is required, and Wireworld asks you to go through that dealer first. The ’In Groove is an authorised Wireworld dealer.
