REL Acoustics 10 Meters Bassline Blue High-Level Subwoofer Cable - BASSLINE 10M

REL Acoustics BASSLINE 10M 10 Meters Bassline Blue High-Level Subwoofer Cable in Blue

The REL Acoustics BASSLINE 10M Bassline Blue high-level subwoofer connection cable combines 18-gauge solid-core copper construction, optimized conductor geometry and a proprietary filter board for more natural, expressive bass. Connecting your amplifier's speaker terminals to the subwoofer's SpeakOn high-level input gives the subwoofer the same source signal as your main speakers. Designed to refine an established music or home theater system, it aims to bring greater clarity, warmth and dynamic ease across the soundstage, with more distinct vocals and better separation between instruments.

Key Features

Purpose-Designed High-Level Integration

A cleaner transition from subwoofer to main speakers is the goal of this connection. Developed for the high-impedance termination at REL Acoustics filter-board inputs, the cable incorporates a proprietary filter board intended to preserve the signal, provide appropriate impedance matching and help define bass more clearly. The design treats the high-level connection as a working part of the complete subwoofer system.

Sound Illuminated

The emphasis is on contrast and dynamic shading, not extra brightness. Optimized conductor geometry is intended to keep bass expressive while revealing voices, spaces between notes and acoustic separation in a recording. REL Acoustics seeks a more open, spacious presentation that stays natural and unobtrusive, including in older installations.

18-Gauge Solid-Core Copper Construction

Grain-aligned, slow-drawn copper is paired with selected twists, terminations and listening-tested connectors. Hand assembly and carefully chosen silver solder reflect a focus on engineering and manufacturing consistency rather than exotic technology. The copper wire is drawn, cleaned, jacketed and printed in the United States; durable materials and discreet proportions complete the design.

System Matching and Setup

REL Acoustics identifies Serie S and Reference systems as well positioned to reveal this upgrade. Improvements in dynamics, integration and soundstage resolution depend on the system's capabilities. This is the standard cable, with separate versions for certain amplifiers.¹

After replacing the standard cable, REL Acoustics suggests 1-2 more crossover clicks and one, at most two, additional gain clicks. That guidance gives existing owners a starting point for refining the subwoofer-to-speaker transition after the upgrade.

Footnotes:

¹ Special impedance-matching circuitry and stackable banana plugs apply to separate NAIM versions, not this standard cable. REL Acoustics recommends a dedicated version for Audio Research, D'Agostino and CH Precision amplifiers; that version's circuitry and plugs are not features of this standard cable.
