Synergistic Research Atmosphere Excite SX Speaker Cables

Pure Silver AirStrings, Multi-Geometry Construction and System-Specific Tuning

The Synergistic Research Atmosphere Excite SX Speaker Cables combine high-current Silver Matrix conductors with handcrafted pure-silver AirStrings in an eight-geometry stereo speaker cable designed for premium two-channel audio systems.

Positioned between Alive SX and Euphoria SX in the Atmosphere SX speaker cable family, Excite SX introduces pure-silver AirString technology alongside the Silver Matrix architecture used in Alive SX. Each speaker cable incorporates four separate conductor geometries, bringing the total to eight across a stereo pair.

Synergistic Research also incorporates its graphene-based UEF treatments, an extended high-voltage conditioning process developed for its SRX cable program, and two included Galileo SX Gold Tuning Modules. The tuning modules give listeners a way to compare the manufacturer's intended sonic presentation with and without the modules installed.

Handcrafted in California, Excite SX is intended for listeners who want to explore Synergistic Research's combination of multiple conductor geometries, sealed-air insulation and adjustable cable tuning without moving to the more elaborate Euphoria SX or flagship SRX designs.

 

Eight Separate Conductor Geometries

Excite SX uses four separate conductor geometries per speaker cable, for a total of eight across a stereo pair.

Each channel combines two high-current Silver Matrix runs with two pure-silver AirString runs. Rather than relying on one uniform conductor design, Synergistic Research combines these different constructions to achieve its intended balance of current delivery, detail and tonal presentation.

The Silver Matrix assemblies provide the high-current portion of the architecture, while the AirStrings introduce the company's sealed-air pure-silver conductor technology.

This combination distinguishes Excite SX from Alive SX, which uses Silver Matrix conductors without the additional pure-silver AirStrings.

High-Current Silver Matrix Conductors

Excite SX incorporates four high-current Silver Matrix assemblies across the stereo pair.

These use a silver-copper matrix conductor construction with a separate ground conductor isolated from the shield. The manufacturer specifies modified polyethylene insulation and silver Mylar shielding.

Synergistic Research also evaluates conductor direction before assembly as part of its manufacturing process.

The Silver Matrix conductors form the foundation of Excite SX's multi-geometry design, working alongside the AirStrings rather than being replaced by them.

99.9999% Pure Silver AirStrings

One of Excite SX's defining upgrades over Alive SX is the addition of pure-silver AirString technology.

Each speaker cable incorporates two handcrafted AirString runs using 99.9999% pure monocrystalline silver conductors.

The conductors are housed in a sealed-air dielectric, reducing their physical contact with solid insulating materials.

Air has very low dielectric absorption, making it useful in cable designs intended to minimize conductor-insulation interaction.

Synergistic Research associates its AirString technology with improvements in perceived detail and spatial presentation. In Excite SX, the company combines these conductors with the Silver Matrix assemblies to achieve its intended sonic balance.

Atmosphere SX UEF Treatments with Graphene

Excite SX incorporates Synergistic Research's Atmosphere SX UEF treatments, including two graphene-based formulations applied to selected areas of the cable.

According to the manufacturer, these treatments are applied to the connectors, cabling and grounding elements to address unwanted electrical noise and mechanical interaction.

The UEF architecture forms part of Synergistic Research's broader approach to managing the electromagnetic environment surrounding audio cables.

The company attributes a reduction in perceived noise and improvements in tonal presentation to these treatments. Those effects are manufacturer-reported design objectives rather than independently established listening results.

Galileo SX Gold Tuning Modules

Excite SX includes two Galileo SX Gold Tuning Modules.

These accessories connect to the cable's dedicated tuning circuits and allow owners to compare the cable's presentation with and without the modules installed.

Synergistic Research describes the Gold modules as providing greater musicality, a smoother presentation and additional perceived air and detail.

The tuning system is particularly useful for customers who want to experiment with the manufacturer's intended voicing options in their own listening rooms.

How to Use the Gold Tuning Modules

Synergistic Research recommends installing Excite SX and allowing the cables to settle into the system for approximately 72–96 hours without removing or handling them and without attaching the Gold modules.

After this initial period, listen to familiar recordings with the modules disconnected. Then install the Gold modules and repeat the comparison.

The manufacturer recommends selecting whichever configuration is preferred in the individual system.

Unlike Euphoria SX, which includes both Gold and Silver modules, Excite SX comes standard with Gold modules.

 

SRX Long-Duration High-Voltage Conditioning

Following assembly, Excite SX undergoes Synergistic Research's extended high-voltage conditioning process, which the manufacturer calls Quantum Tunneling.

Developed during its SRX cable program, this process applies high-voltage treatment at selected frequencies and pulse modulations over an extended period.

Synergistic Research specifies treatment using one million volts and attributes changes in conductor and contact behavior to the process.

The treatment is part of the company's manufacturing approach rather than a feature requiring any additional electrical connection or maintenance by the customer.

Handcrafted Construction and Factory Burn-In

Excite SX is handcrafted at Synergistic Research's California factory.

The manufacturer's published specifications identify 18 point-to-point hand-soldered connections using 4% silver solder.

Additional manufacturing steps include its graphene-based UEF treatments, a secondary UEF Blue treatment originally developed for the company's SR Blue Fuses, and SRX long-duration high-voltage conditioning.

After assembly, the cables undergo a five-day, two-stage factory burn-in process.

The manufacturer lists approximately 4.5 hours of hand-build time for the standard configuration.

Choosing Excite SX for Your Audio System

Excite SX is designed for premium two-channel audio systems in which speaker cable construction, connection quality and system matching are important considerations.

Its combination of Silver Matrix and pure-silver AirString conductors offers a different construction from conventional stranded copper speaker cables. The included Gold Tuning Modules also provide an opportunity to experiment with Synergistic Research's approach to cable voicing.

Before ordering, confirm the required length and the connection types at both your amplifier and loudspeakers.

Excite SX is available with SR BoFa banana and SR Silver spade connectors. The appropriate configuration depends on the binding posts used by your equipment and the available installation clearance.

Customers with bi-wireable loudspeakers should also determine whether a conventional single-wire connection is appropriate or whether they require a separate bi-wire arrangement.
