Blue Jeans Cable Canare 4S11 Speaker Cable with Ultrasonic Bi-Wire Terminations, 20 ft Grey – Two Bananas to Four Bananas, Assembled in Seattle

Overview

Meet the Blue Jeans Cable Canare 4S11 Speaker Cable, a purpose-built bi-wire path designed for clarity and reliable performance. At 20 feet, the grey jacket provides ample reach for typical stereo or integrated-system layouts, while the two-conductor-at-the-amp end and four-conductor-at-the-speaker end support distinct signal paths for left and right channels. This cable is designed to complement a wide range of components from integrated amps to dedicated receivers, offering flexibility without compromising build quality.

Premium construction and thoughtful engineering are evident in every detail. The cable uses Canare 4S11 conductors and ultrasonic-welded terminations that fuse copper directly to brass connectors, with no intervening metal layers, sleeves, or setscrews. This approach aims for a clean electrical path and reduces weak points where signal could degrade over longer distances or with vigorous playback.

Design and performance advantages

The star quad layout minimizes electromagnetic interaction with nearby cabling, which can contribute to lower crosstalk and a more stable image in some setups. Assembly happens in Seattle at Blue Jeans Cable's own shop, using proprietary connectors and a Sonobond welder. Locking banana plugs enhance engagement between plug and binding post, and the locking collar tightens the splines to help maintain a secure connection over time.

Key features at a glance

• Bi-wired configuration: two connectors at the amp end, four at the speaker end.
• Ultrasonic-welding: copper fused directly to brass connectors with no sleeves or setscrews.
• Star quad design to reduce EM field interaction with other cabling.
• Assembled in Seattle, using proprietary connectors and Sonobond welder.
• Locking banana plugs for secure plug-to-post engagement.

Real-world use and considerations

In a typical home audio setup, a 20-foot run offers flexibility in speaker placement while aiming to preserve signal integrity over medium distances. Possible benefits include more defined imaging, clearer nuances in playback, and a coherent center image, though outcomes depend on your gear, room acoustics, and power delivery. The design emphasizes consistent performance and durability as part of a well-built signal path.

Ideal use scenarios

• Stereo and home theater systems requiring a true bi-wire path.
• Longer speaker runs where termination quality matters for signal integrity.
• Systems using locking banana plugs for secure connections.

Maintenance is straightforward: inspect connections after setup, keep bananas seated firmly, and avoid sharp bends near terminations. The grey jacket blends with many rooms and remains durable under regular use.
