AudioQuest Lone Ranger Full-Range Speaker Cable

AudioQuest Lone Ranger Full-Range Speaker Cable with ZERO-Tech

Featuring tried-and-true AudioQuest design elements along with ZERO-Tech for no characteristic impedance, Lone Ranger has significantly more conductor metal than its predecessors while being more physically manageable thanks to its positive and negative sides being housed in separate round constructions. The result is a quieter cable that delivers a more muscular overall presentation. Perfect for full-range applications, Lone Range can also be partnered with AudioQuest BigFoot BASS cable (coming in 2026) for BiWiring configurations.

Slightly smaller than Brave Heart (11.6mm OD vs Brave Heart's 14.1mm OD per polarity) and boasting the same friendly construction that places positive and negative sides in discrete housings, Lone Ranger offers a remarkable sonic improvement over its predecessor characterized by eye-opening resolution and presence, realistic dynamic ease, and a surprisingly authoritative overall presentation.

Like its larger sibling, Lone Ranger meaningfully blurs the line between Folk Hero and Mythical-level sound quality. How is this achieved? Lone Ranger features many of the same upgrades that make Brave Heart such a thrilling success.

• Almost one-third more PSC+ Copper for lower impedance, smoother frequency response (regardless of speaker impedance curve), and a more muscular presentation.
• Superior polypropylene dielectric (insulation) linearizes and expands the bandwidth of noise-dissipation.
• Optimized dielectric reduces out-of-focus, harsh-sounding distortion due to distributed capacitance.
• Thicker Carbon-Loaded PVC, added Graphene layer, and 4% silver shield drain wires further improve RF-Noise Dissipation.

Permanent Molecular Optimization (PMO) does not replace the important aural benefit of playing music over extended periods of time. Music (modulated AC signal) slightly stresses the dielectric and connection interfaces, significantly benefitting cable performance.

PMO is a controlled extreme stressing of the materials — a near-death experience for them — that significantly and permanently (unlike running-in) helps the cable get out of the music's way.

All this is complemented by several important tried-and-true AudioQuest design elements. These include:

• Solid conductors prevent strand interaction.
• Direction-controlled conductors efficiently drain RF noise away from the vulnerable amplifier circuitry — toward where it will do the least or no harm.
• ZERO-Tech eliminates characteristic-impedance mismatches between the cable and the attached source and load, allowing power to flow seemingly unencumbered, presenting sound and music with remarkable ease.
• The constant DC potential (in contrast with running-in and PMO’s AC stressing) of AudioQuest’s 72v Dielectric-Bias System polarizes the dielectric (insulation), significantly reducing Dielectric-Noise (energy stored in the dielectric being released out of time and at other frequencies). DBS also linearizes (makes more consistent across a wide band) Radio-Frequency Noise-Dissipation.
• There is no metal in the cable dressings or plug barrels, which would reradiate and capacitive-couple RF-Noise into the cable. Cold-welded gas-tight connections are made to Red Copper spades or bananas.

Our Review

The AudioQuest Lone Ranger Full-Range Speaker Cable is a seriously impressive evolution in AudioQuest’s lineup — a cable that blends technical brilliance with a sense of effortless musicality. It takes many of the innovations that made Brave Heart such a standout and refines them into a more manageable form, with separate round housings for positive and negative conductors, delivering a cleaner, quieter signal and a sound that feels powerful yet unforced. Its generous use of PSC+ copper, advanced ZERO-Tech design for zero characteristic impedance, and 72v Dielectric-Bias System all work together to open up the soundstage with stunning resolution and ease. Add to that a superior polypropylene dielectric, graphene-based noise dissipation, and Permanent Molecular Optimisation for permanently “run-in” performance, and you get a cable that feels alive with texture and tone. In use, Lone Ranger brings music to life with remarkable authority and presence — a perfect blend of muscle, finesse, and clarity that makes every listening session feel just a bit more special.
