Synergistic Research Foundation XL Speaker Cable

Synergistic Research Foundation XL Speaker Cable

Foundation XL Speaker Cable applies the learnings from Synergistic Research's flagship SRX XL cable line to the Foundation series, doubling the 6N pure silver Air Strings for improved immediacy, resolution, dynamics, and transient response. Like other Foundation series speaker cables, a pair of Foundation XL consists of four separate cables, two for positive and two for negative, an arrangement that improves the cable's overall electrical characteristics. Every cable uses SRX XL Matrix Shielding with Graphene and is treated with SRX XL High Voltage Conditioning, the same process developed for Synergistic Research's flagship SRX XL cables. Included Gold and Purple Carbon Tuning Discs let you further refine the cable's voicing. As an authorized Synergistic Research dealer in Toronto, Canada, Vinyl Sound can help you match this speaker cable to your amplifier and speakers.

Frequently Asked Questions

What's the difference between the Banana and Spade connectors?
Both are SR Silver connectors, choose whichever matches your amplifier and speaker terminals. Vinyl Sound can help confirm which connector type fits your system before you order.

Do the Carbon Tuning Discs need to be swapped for different music genres?
No, they're a one-time voicing choice for your system. Try Gold and Purple individually and keep the one that best matches your amplifier and speakers.
