Shielded Cat6 Ethernet Cable
Hardwiring the Arc soundbar disables its reliance on the primary Wi-Fi network for data ingestion, allowing the internal radio to dedicate its full bandwidth to the 5GHz ad-hoc backhaul used by the Sub. This eliminates interference-induced packet loss and Spanning Tree Protocol loops that cause the Sub to intermittently drop from the system.

Ultra High Speed HDMI 2.1 Cable (48Gbps)
The eARC (Enhanced Audio Return Channel) protocol requires high-bandwidth stability to maintain the audio handshake between the TV and Arc. An Ultra High Speed cable ensures that high-bitrate codecs like Dolby Atmos do not suffer from signal attenuation or EMI, which can cause the Arc to momentarily lose sync, subsequently dropping the Subwoofer's audio feed.

Replacement AC Power Cord (Figure-8)
High-excursion vibrations from the Subwoofer's dual drivers can cause a loosely seated or worn figure-8 power connector to momentarily lose electrical contact. A new, tight-fitting cable ensures consistent power delivery during heavy bass transients where mechanical cabinet vibration is at its peak.
