【ULTIMATE SC SP-BN (265cm)｜Speaker Cable for High-End Car Audio】

Even after swapping the speakers or adding an amplifier, the sound doesn’t become as cohesive or information-rich as you expected. In such cases, it’s worth looking not only at the speakers or amplifier, but also at the speaker cable that delivers the audio signal.

ULTIMATE SC SP-BN (265cm) is a high-end class speaker cable designed for those who want to carefully refine the entire car audio system.

For the conductor, it uses high-quality BRC copper. The conductor diameter is 5.50mm² (equivalent to 10AWG)—a size that’s easy to match with systems where you want to make the most of the performance of your speakers and amplifier. Sound differences due to cables aren’t determined by the cable alone, but choosing the right one based on the equipment you use and your system configuration can help organize and improve the sound’s information content and cohesiveness.

For the outer construction, it adopts insulation based on an original two-layer structure and a nylon mesh jacket designed with abrasion resistance in mind. It’s built not only for excellent tactile appearance, but also to be durable for long-term use in a vehicle.

However, speaker cables shouldn’t be selected based on thickness and material alone. You also need to consider the amplifier’s output, the speakers’ specifications, wiring distance, mounting method, and how the cable is routed inside the car. If I were choosing, I wouldn’t decide on the cable first—I’d confirm your current system and the direction you plan to go, then make the selection.

At LOGON, we guide you to a reasonable combination while asking about your vehicle model, system configuration, and your preferred sound. Since it’s a set of genuinely high-end components, we’d like to finish the setup in a way that you can use for a long time with comfort and confidence—including how the wiring is handled and how reliably everything is connected.

Because this is a made-to-order product, if you’re considering adopting it for your system, please tell us your current audio setup and what you want. We’ll help you sort out the sound direction together and also advise whether there’s a meaningful reason to use this cable.
