Top 7 Best Subwoofer Cables

#1 Blue Jeans Cable LC-1 Double-Shielded Low Capacitance Subwoofer Cable

First on my list is the Blue Jeans Cable LC-1, Blue Jeans is new in the market but is standing out for its excellent quality products. The high-quality rubber insulation is .30 in diameter that makes this cable quite thick. 

The copper wire used in the cables is made of low-capacitance copper for maximum signal flow. 

The cables have two individual braided shields that are securely connected to gold-plated high-quality RCA connectors. 

This subwoofer cable is available in different lengths and is also available to customize as per your desire. The cable is UL listed and CM rated making it perfect to use for in-wall installments. 

With the advantage of the subwoofer wire being thick, it is not what you want to use for under carpet wiring as it can create a hindrance.

#2 Audioquest SUB-1 Silver Serpent Anniversary Edition RCA Audio Interconnect Cables

Here is a cable company that needs no introduction called Audioquest, they have been making audio cable and equipment over the years and are really good at it. The Audioquest SUB-1 is my favorite from the brand because of its silver-plated copper conductors than your regular copper. 

It has a stranded core than the solid core that is favored by most audiophiles but the silver-plated copper wires still offer an excellent signal transfer. With a 100 ft long wire, the signal loss is as little as .3db which is quite impressive. 

A copper shield is isolated around the wire to reduce noise pick up and provide extra support making the wire sturdy for long-term use. 

Without a doubt, this is an excellent choice to improve the low end of your home theater set up.
