16 Gauge, 2-Conductor, Behind-the-Wall Speaker Cable


When your setup requires installing your cable behind a wall or ceiling, use this 16 gauge, UL-rated CL3 economy cable to stay within USA building codes and within your budget.

It is made of 99.99% Oxygen-free copper and includes a layer of foil shielding to prevent unwanted interference and hum induced by surrounding electrical wires.

The CL3-rated outer-jacket is UL listed and meets all building codes in the USA for fire retardancy. It does not include the CSA mark and therefore may not pass inspection in Canada.

Run this 2-conductor cable (+ and -) to a single speaker. General convention is to use RED for positive (+) and BLACK for negative (-).

Speaker cable is made of individual strands of copper that are twisted together to result in the cable's thickness, or gauge. The lower the gauge, the thicker the cable, e.g. 14 gauge is thicker than 16 gauge. Generally speaking, thicker cable will result in less signal loss over a given length. With the recent rise in the cost of copper, we now offer 16 gauge cable as a more economical means of running all of your speaker cable. For many of our customers, the money saved vs 14 gauge cable is better spent upgrading their speakers. For others, quality 16 gauge cable is sufficient for their listening taste and the price savings helps keep their project on budget.

When evaluating cable, it is also important to know the number of individual strands that are used to produce the overall gauge. Electrons will follow the path of least resistance which tends to be on the surface area of the copper. So the more individual strands used, the greater the available surface area, and thus less signal loss. Typical CL3-rated 16 gauge speaker cable that you'll find at consumer electronics stores is manufactured with a strand count of 12. In contrast, ours utilizes 41 individual strands of 99.99% oxygen free cable.

Some popular cable manufacturers also use this high strand count but they will cost you about double our prices simply because they sell through distributors and retailers. And with the recent rise in the price of copper (due to strong worldwide demand), the amount you'll spend wiring your home for sound has become a significant part of your home audio budget.

With HTD speaker cable you get the quality you need at a price that won't break your budget.
