Reference RCA subwoofer cable

The Reference RCA Subwoofer Cable is designed for audiophiles who demand the deepest, cleanest, and most powerful bass performance from their audio system or home cinema setup. A subwoofer (or “sub”) is a specialised loudspeaker engineered to reproduce the lowest frequencies in the audio spectrum — typically between 20–200 Hz for consumer systems, below 100 Hz for professional live sound, and under 80 Hz for THX-certified systems.

Subwoofers work in harmony with your main loudspeakers, extending the frequency range to deliver a fuller, more immersive sound. The Reference RCA Subwoofer Cable ensures this integration is seamless, precise, and sonically transparent.

Precision & Purity

The Reference RCA Subwoofer Cable employs dual, separately routed shields that protect audio data from external interference. With a precisely engineered 75-ohm impedance, it transmits the digital signal with perfect accuracy and timing. The result is a natural, dynamic sound ideal for high-resolution audio formats and cinematic experiences alike.

Each cable features solid 24-carat gold-plated connectors, ensuring maximum conductivity and minimal signal loss. The outcome? Deep, resonant bass with extraordinary control and definition that brings every soundtrack to life.

Next-Generation Performance

Introduced in June 2021, the Reference S Subwoofer Cable represents the next step forward in sub-bass reproduction and performance. Enhanced with Anti-static isolation material, it enables your system to reveal lower frequencies that were previously hidden. This added layer of refinement allows the subwoofer to operate more efficiently and reproduce bass that feels alive, tactile, and immersive.

You don’t just hear the bass — you feel it. Explosions, rumbles, and musical lows gain realism and presence that pulls you right into the performance.

Noise Reduction

Unwanted noise and vibration are the enemies of true low-frequency performance. To combat this, Perkune’s Reference Series employs double-layer AirGap shielding, dual-layer Teflon isolation, dual vinyl insulation, and PE dielectric protection.

Each cable is also fitted with two Anti-static pads, reducing the impact of micro-vibration, EMI, and static buildup. The result is an astonishingly clean signal path — free from distortion and interference — allowing your subwoofer to perform at its absolute best.

Performance

The Reference RCA Subwoofer Cable exceeds expectations in every category. Bass notes are perfectly positioned, balanced, and delivered with a sense of weight and realism rarely heard in consumer systems. You’ll notice greater dynamic contrast, a deeper soundstage, and a physical sense of impact that brings your listening experience to life — whether it’s a thunderous movie explosion or the subtle resonance of an upright bass.
