Synergistic Research SRX XL Speaker Cables

Flagship Pure Silver Speaker Cables with 32 Separate Conductor Geometries

The Synergistic Research SRX XL Speaker Cables represent the company's expanded approach to reference-level speaker cable design. Built around 32 individual conductor geometries per stereo pair, SRX XL combines handcrafted pure-silver AirStrings, fourth-generation Tricon conductors, advanced graphene-based shielding and an integrated system of carbon-fiber cable supports.

Developed as an evolution of the original SRX Speaker Cables, SRX XL increases the number of pure-silver conductors and introduces a revised UEF Matrix Shield and an extended high-voltage conditioning process. The design is intended to manage electromagnetic interference, conductor interaction and the mechanical environment surrounding the cable while retaining flexibility for installation.

Each standard 8-foot stereo pair includes eight Carbon Performance Elevators, carbon-fiber spacers and interchangeable Gold and Master UEF Tuning Modules. The cables are handcrafted in California, with additional lengths available to order.

 

Expanded 32-Geometry Conductor Architecture

The defining feature of SRX XL is its elaborate conductor arrangement. Each stereo pair incorporates 32 separate geometries: twelve 14 AWG pure-silver AirStrings, sixteen pure-silver monofilament AirStrings and four fourth-generation Tricon conductors.

This is a substantial expansion over the original SRX Speaker Cable's 20-geometry construction.

Rather than placing every conductor inside a single conventional cable jacket, Synergistic Research uses individually isolated geometries and strategically positioned carbon-fiber spacers. The company developed this construction to manage interaction between the conductors and provide a controlled mechanical environment.

For customers building a reference-level audio system, SRX XL offers a distinctive alternative to conventional multi-strand or single-geometry speaker cable designs.

99.9999% Pure Silver AirString Conductors

SRX XL incorporates two different pure-silver AirString configurations.

The first consists of twelve 14 AWG conductors made from 99.9999% pure monocrystalline silver. The second uses sixteen second-generation pure-silver monofilament AirStrings.

Both employ sealed-air dielectrics and Synergistic Research's UEF Ground Plane Technology.

Air is a desirable dielectric because it minimizes contact between the conductor and solid insulating materials. Synergistic Research uses this construction as part of its approach to reducing dielectric interaction and managing unwanted electromagnetic energy.

By increasing the number of silver AirStrings relative to the original SRX, the manufacturer aims to improve transient reproduction, dynamic expression and low-level detail.

These are the manufacturer's stated performance objectives; the audible result will depend on the complete playback system.

Fourth-Generation Tricon Conductors

Alongside the pure-silver AirStrings, SRX XL incorporates four fourth-generation Tricon conductors.

These use monocrystalline silver/copper matrix conductors, PTFE insulation and a triaxial geometry.

The Tricon assemblies introduce a different conductor structure into the cable, complementing the two AirString configurations.

Synergistic Research also specifies that the conductors are evaluated for signal direction before assembly.

The combination of AirString and Tricon technologies allows the company to use different conductor geometries within the same speaker cable rather than relying on a uniform construction.

Eight UEF Cell Assemblies

SRX XL includes eight UEF Cell assemblies incorporating 99.9995% pure-silver ribbon and copper elements.

These assemblies use Teflon insulation, multiple silver/copper conductors and gold-plated 2.5 mm tuning-circuit connectors.

They form part of the cable's broader electromagnetic-field management and tuning architecture.

Together with the AirStrings, Tricon conductors and UEF Matrix Shield, the UEF Cells contribute to the specialized construction of SRX XL.

SRX XL UEF Matrix Shielding with Graphene

SRX XL introduces a revised UEF Matrix Shield formulation incorporating graphene.

Synergistic Research developed the shielding compound specifically for the XL series, building on the technology used in its earlier SRX cables.

The UEF coating is applied directly to the connectors as part of the cable's electromagnetic noise-management system.

According to the manufacturer, the revised formulation is intended to reduce unwanted noise while minimizing the restrictions that shielding can introduce to signal transmission.

The shielding system works alongside the cable's UEF Ground Plane Technology and individual conductor geometries.

Gold and Master UEF Tuning Modules

One of SRX XL's distinguishing features is its interchangeable tuning system.

Each stereo pair includes four Gold SR25 UEF Tuning Modules and four Master UEF Tuning Modules. These passive accessories connect to the cable's dedicated tuning circuits and operate outside the audio signal path.

Synergistic Research provides the two configurations so customers can experiment with the cable's presentation in their own systems.

The manufacturer describes the Gold modules as emphasizing warmth and fluidity, while the Master modules are intended to emphasize detail and refinement.

The suggested procedure is to allow the cables to settle into the system for 48–72 hours before comparing the tuning options.

This gives customers a degree of system-specific adjustment without changing the cable's primary signal connections.

SRX XL High-Voltage Conditioning

Following assembly, SRX XL undergoes Synergistic Research's extended high-voltage conditioning process, which the company calls Quantum Tunneling.

The manufacturer specifies treatment using one million volts at selected frequencies and pulse modulations. For SRX XL, the procedure incorporates longer-duration frequency sweeps and revisions to its conditioning equipment.

Synergistic Research attributes changes in conductor and contact behavior to this treatment and considers it an important part of the cable's manufacturing process.

These proposed effects are manufacturer claims rather than independently established performance measurements.

Carbon-Fiber Performance Elevators and Spacers

The standard SRX XL stereo pair includes eight Carbon Performance Elevators with integrated HFT elements, along with 24 carbon-fiber spacers.

The elevators support the cables above the floor, while the spacers maintain separation between individual conductor assemblies.

Synergistic Research developed these accessories as part of its approach to managing the cable's mechanical environment and electromagnetic-field interactions.

Unlike aftermarket cable supports purchased separately, these components are included in the SRX XL package and form part of its intended installation.

Their physical dimensions and placement should be considered when planning cable routes around equipment racks and loudspeakers.

Handcrafted Construction and Factory Burn-In

SRX XL is handcrafted at Synergistic Research's California factory.

Each stereo pair incorporates individually isolated cable geometries and 52 point-to-point hand-soldered connections using 4% WBT silver solder.

After assembly and high-voltage conditioning, the cables undergo a five-day, three-stage factory burn-in process.

This extensive construction distinguishes SRX XL from conventional speaker cables and makes it particularly important to establish the correct length and termination configuration before ordering.

Choosing SRX XL for Your Reference Audio System

SRX XL is intended for substantial two-channel audio systems in which the amplifier, loudspeakers, room and supporting components have been carefully selected.

Before ordering, the most important practical decisions are cable length, amplifier-end and loudspeaker-end terminations, and the available space for routing the individual conductor assemblies and included elevators.

Synergistic Research specifies its BoFa banana and Gold spade connectors for this model. We recommend confirming the required configuration for both ends of the cable, particularly when working with amplifiers or loudspeakers that have unusual binding-post arrangements.

Customers using bi-wireable loudspeakers should also determine whether they need a conventional single-wire connection or the manufacturer's separate SRX XL IFT Bi-Wire accessory.
