The BINARY B3-SUB-2 is a subwoofer cabinet interconnect cable in the B3 Series lineup, designed to carry low-frequency audio signals between a subwoofer amplifier and a subwoofer enclosure or powered subwoofer unit. At 6.5 feet in length, it provides a practical run for rack-to-speaker or component-to-component connections in residential and light commercial audio installations. The cable ships as a single unit and is suited for AV integrators, home theater installers, and low-voltage technicians working with dedicated subwoofer channels in distributed audio or home theater systems.
The B3-SUB-2 is intended for use in residential home theater builds and light commercial audio setups where a reliable, dedicated subwoofer interconnect is needed. It is part of the BINARY B3 Series, a line oriented toward professional AV integration work. Typical installation scenarios include connecting an AV receiver or processor subwoofer output to a powered subwoofer, or linking a subwoofer amplifier module to a passive enclosure.
Designed as a subwoofer interconnect cable for use within the BINARY B3 Series. Compatible with standard subwoofer-level inputs and outputs found on AV receivers, processors, and powered subwoofer units that use the same connector format.
Installation is performed by low-voltage AV technicians or licensed electricians working under applicable low-voltage codes. Power down all associated audio components before connecting or disconnecting signal cables to prevent damage to amplifier stages. Route the cable away from AC power lines and high-voltage conductors to minimize hum and interference. Secure any excess cable length to avoid strain on connectors at either termination point.
