Triangle RED - Subwoofer 3m
Overview
With its Black and Red ranges, French manufacturer Triangle is extending its catalogue beyond loudspeakers. This Y‑configured RCA cable connects the subwoofer output of a Hi‑Fi amplifier or home cinema amp to the inputs of an active subwoofer. The 3‑metre length (also available in 5 metres) provides enough leeway to place the subwoofer freely in the room, without being constrained by proximity to the source electronics.
A multi-strand, ultra‑pure OFC copper conductor
The conductor uses OFC (Oxygen Free Copper) with a purity level of 99.99%. This type of copper, produced using a process that removes residual oxygen, reduces internal micro‑resistances and promotes high conductivity. Low frequencies, which require a higher current transfer than mids or highs, directly benefit from this low‑impedance structure. The cable is made up of several strands, a geometry that improves mechanical flexibility while distributing the electrical flow evenly.
Triple-layer insulation and reinforced shielding
The RED Subwoofer cable combines several protective barriers. From the outside inwards: a braided cotton sleeve provides mechanical protection and an attractive finish, followed by PVC insulation, an aluminium insulating foil, a braided copper shield, then a second PVC sheath surrounding the conductor. This triple‑layer insulation architecture serves two purposes. First, it blocks electromagnetic and radio‑frequency interference, which is particularly problematic over long runs or near digital devices. Second, it damps mechanical vibrations that could propagate along the cable.
Gold‑plated connectors and directional arrows
The RCA plugs feature gold plating that protects the contact from oxidation and ensures stable conductivity over time. Each connector is clearly identified, which simplifies connection to the subwoofer inputs. The cable also bears an arrow indicating the recommended signal flow direction, from the amplifier’s subwoofer output to the subwoofer input. This marking helps maintain the electrical consistency of the system and prevents connection errors.
Y configuration: a mono signal fed to two inputs
The subwoofer or LFE output of an amplifier delivers a mono signal, as low frequencies are generally summed into a single channel. The Y cable takes this signal at the source via a single RCA plug and feeds it to the two subwoofer inputs through its two output plugs. The subwoofer then sums these two inputs internally before amplification. This configuration addresses a practical constraint: many active subwoofers have a pair of left/right RCA inputs (inherited from older stereo systems without a dedicated sub output) rather than a single LFE input. By feeding both inputs, you avoid leaving one input floating and ensure an optimal signal level. For subwoofers equipped with a single input, one of the two plugs simply remains unused.
Integration into a Triangle or mixed system
Triangle designed this cable to accompany its own active speakers (Borea Connect, AIO Twin, LN01A, LN05A ranges) and its subwoofers (Tales 340, Thetis 300, Thetis 340). The cable of course works with any amplifier or subwoofer featuring standard RCA connectors. Its weight of 190 grams (284 grams in the 5‑metre version) and its flexibility make it easy to route behind furniture or along a skirting board without putting strain on the connectors.

Frequently Asked Questions
What’s the difference between this cable and a standard RCA audio cable?
A subwoofer cable has to carry low frequencies with higher current and often over longer distances than a standard interconnect. The reinforced shielding and larger conductor cross‑section reduce the risk of picking up noise (hum, radio interference), which is more likely to occur over long cable runs.
Can this cable be used with a subwoofer that has only one RCA input?
Yes. Simply connect one of the two Y plugs to the subwoofer’s single input and leave the other plug unplugged. Signal transmission remains the same.
Why use a Y cable if the signal is mono?
Many subwoofers have two RCA inputs (left/right), a legacy of stereo systems without a dedicated subwoofer output. The Y cable allows you to feed both of these inputs from the amplifier’s mono output, ensuring the correct signal level and avoiding leaving one input unused.
Is this cable suitable for a home cinema setup with an LFE output?
Yes. The LFE output of a home cinema amplifier uses a standard RCA connector and delivers a mono signal dedicated to low frequencies. The RED Subwoofer cable connects directly to it.
