Best Subwoofer Cable

A subwoofer cable has the job of delivering a line-level audio signal (typically 0.3 to 0.45 volts) from your A/V receiver, amplfier, or preamp to a powered subwoofer. In many cases, the subwoofer is some distance from the rest of the system, so a good cable must keep signal loss to a minimum. Additionally, quality subwoofer cable must be well-shielded to minimize the pickup of 60 Hz hum from power cables, a frequency right in the sweet spot of a subwoofer's frequency response. RFI (radio frequency interference) can also be an issue. RCA connectors with gold plating are always nice since gold resists corrosion. Our selections below are based on cable capacitance, shielding, and connector quality, and are for mono cables only i.e. single connection point at both ends.

AudioQuest SUB-1 Subwoofer Cable

The AudioQuest SUB-1 is our top choice for good reasons. Three silver-plated conductors and a superior shielding system mean a clean and unattenuated signal will be delivered to your subwoofer. This is a seriously well made interconnect that is worth the price. Read Full Review

    Why it's best:

    If you want a great subwoofer cable, look no further than the AudioQuest SUB-1. This cable features three separate silver-plated solid copper conductors to maximize signal transfer, with each conductor having its own air core insulation layer. All three conductors together are also shielded to effectively eliminate noise, with the shield completely covering the outer sleeve of the RCA connector. The conductors are also sliver-plated copper, and attached with silver paste instead of standard solder. A very nice feature is a separate ground wire which can be connected to further reduce the potential for AC hum.

    This cable is a great choice for audiophiles, and it is not insanely priced. The only caveat would be using this subwoofer cable in systems where the equipment is exposed to moisture. The silver-plated copper is electrically superior, but not corrosion resistant like gold.

    Blue Jeans Cable LC-1 Subwoofer Cable

    You may not have heard of Blue Jeans, but their LC-1 subwoofer cables are very high quality, and literally cut to fit your specifications. Thick, low-capacitance connectors and gold-plated connections mean 100% signal transfer. Plus, the LC-1 is UL and CM rated. Read Full Review

      Why it's best:

      The Blue Jeans Cable LC-1 is a close second to the AudioQuest SUB-1. Blue Jeans is a small company that makes great products. Their LC-2 cable is quite thick - .30 in diameter, and constructed of low-capacitance copper. Each cable has two separate braided shields, with the shields tightly connected to high quality RCA connectors with gold-plated contact points. Additionally, the Blue Jeans LC-1 is UL listed and CM rated for in-wall applications. These subwoofer cables are made to order in the desired length, and can be further customized as needed. The only negative could be the profile and thickness if you are running this under a carpet.

      Silver Serpent Subwoofer Cable

      As its name suggests, the Silver Serpent utilizes silver-plated copper conductors for maximum fidelity, and a claimed signal loss of only .3 db per 100 feet due to its 75 ohm impedance. Shielding is more than adequate, and the outer cover is very sturdy. It's a good, audiophile-grade choice. Read Full Review

        Why it's best:

        This audiophile subwoofer cable has all the essentials for a high quality interconnect. Like the Audioquest SUB-1, the Silver Serpent contains silver-plated copper conductors, but these are stranded core instead of solid. Some audiophiles will prefer solid over stranded wire for these applications, but the silver plating still makes this cable a decided upgrade in terms of signal transfer. The rated signal loss is only .3 dB over a 100 ft run - quite impressive. This subwoofer cable has a bare copper shield to minimize noise pick up, and has a very sturdy outer jacket. The Silver Serpent is a good choice to improve the sound of the bottom octave of your system.

        Monster Cable MC 600SW-8M Subwoofer Interconnect

        This subwoofer cable from Monster has the basics covered: dual copper conductors, shielding to reduce various sources of interference and noise, and gold-plated connectors. It also boasts a "high frequency network" for upper subwoofer frequencies. This is a good cable suitable for use in home or in the car, but may not be quite audiophile grade. Read Full Review

          Why it's best:

          The Monster Cable 600SW subwoofer cable is yet another quality subwoofer cable from a company known for their interconnects and speaker wire. The 600SW has two solid-core copper conductors to carry low frequencies with another wire network designed to deliver higher frequencies which, when lost, can result in less defined articulation. Like all quality cables, this subwoofer cable has a shield to reduce EMI and RFI noise. And the flexible outer cover, and gold-plated RCA connectors makes this a useful cable for both home and car applications. This is a product is a typical Monster offering - high-quality and priced within reach.

          Mediabridge Ultra Series Subwoofer Cable

          If you need a quality interconnect that definitely won't break the bank, this is your choice. It has some compromises (aluminum shielding) but still boasts gold-plated RCA connectors. Capacitance and impedance are not listed, but have no doubt that this cable will deliver signal just fine, although not to some audiophile's requirements. Read Full Review

            Why it's best:

            The last entry in our Best Subwoofer Cable category is not really in the same league as the first three, but it still is a very capable interconnect and a bargain. This Mediabridge subwoofer cable uses a single copper conductor with a double shield system consisting of copper and aluminum along the entire jacket. Aluminum keeps the price down, and works well as a shield at lower frequencies (less so at higher frequencies). Gold-plated RCA connectors finish this nice choice for music lovers on a tight budget. And, unlike most subwoofer cables, the Mediabridge Ultra Series is also perfectly suited to being used as a digital audio or video cable. So if you upgrade later, this will still be a useful interconnect.
