Blue Jeans Cable Canare 4S11 Speaker Cable - Ultrasonic Bi-Wire

In this review the Blue Jeans Cable Canare 4S11 speaker cable is evaluated for listeners seeking a practical upgrade to speaker wiring without exotic claims. The single biggest reason to buy is the termination quality: this cable uses an ultrasonic welding process that fuses copper directly to brass bananas or spades for a consistently solid, low-resistance connection. For anyone bi-wiring floorstanders or bookshelf speakers with separate HF and LF posts, the built-in bi-wired configuration and locking bananas make setup straightforward and reliable.

Key Features

• Bi-wired configuration: Two connectors at the amp end and four at the speaker end let users separate high- and low-frequency paths for improved system tuning and flexibility.
• Ultrasonic welded terminations: The copper conductors are fused directly to the brass connectors, eliminating intermediate metal and reducing potential contact resistance.
• Star quad conductor: The cable geometry reduces EM field interaction with nearby cabling, which helps keep channel separation and reduces noise in complex setups.
• Locking banana plugs: The locking collars tighten splines against binding posts for a secure mechanical and electrical connection that resists accidental pullout.
• Assembled in USA: Hand-assembled in Seattle with proprietary connectors and Sonobond welding provides consistent build quality and traceability.

Who It's For

The Blue Jeans Cable Canare 4S11 suits home audio enthusiasts who want a practical, well-terminated bi-wire cable without spending on boutique pricing; it is particularly useful for those who value reliable banana and spade connections and who run separate high/low speaker inputs. AV hobbyists moving from basic crimps or screw terminals will notice cleaner bass and a firmer mechanical feel at the binding post.

Those who need custom lengths under professional installation constraints or who insist on exotic conductor metallurgy should look elsewhere; this product is focused on smart geometry and industry-leading terminations rather than marketing exotic materials.

Pros & Cons

Pros

• Outstanding connector integrity thanks to the ultrasonic welding that removes intermediate metals and setscrews.
• Secure mechanical connection with locking banana plugs that reduce intermittent contact and improve reliability.
• Star quad layout minimizes electromagnetic interaction, helping maintain sonic clarity in dense cable runs.

Cons

• Some users report mixed long-term durability, so very heavy use or repeated reterminations may reveal wear on connectors or cable jacket.

Frequently Asked Questions

Is this cable bi-wire ready?
Yes. It terminates as two connectors at the amp end and four at the speaker end for bi-wiring.

Are the plugs secure on binding posts?
Yes. The locking banana plugs tighten via a collar that presses splines into the post for a secure fit.

Where is the cable assembled?
It is hand-assembled in Seattle, Washington using proprietary connectors and a Sonobond ultrasonic welder.
