Features & Specifications

If your run exceeds 200 feet, consider using a 12 gauge cable like this 2-conductor cable that is CL3 rated and specifically designed for the outdoors. If you plan to bury the cable, OSD recommends you bury it 4-6” underground so that it's not visible nor pose a danger of somebody tripping over it. Always use CL3 rated outdoor speaker wire which is designed for the outdoors and can can withstand extreme weather conditions like rain, snow and high temperatures and incorporate twice the insulation. These cables also use formulated white polyethylene jacket that is U/V resistant so it will stand up to the sun.

The cable features a specially formulated white polyethylene jacket that is U/V resistant and provides protection against water damage. The audiophile grade wire contains 168 strands of 99.9% pure copper conductors. The high strand count provides improved skin effect.

Hi Alvin:

The 12 gauge will most likely work for your application but we are limited to two colors Black or White Jacket. It also looks like you will be dealing with Fresh Water versus Saltwater. I would check with a marine wire supply for more choices for colors. And talk to an expert in marine wire, seems to meet they have different specs in that industry.

I want to place outdoor speakers on my deck.  My deck is in bright sunlight all afternoon and into the late evening.  Each speaker will sit under an overhang between two bay windows.  Some of the wire may be exposed to the elements.  Would that be a problem with this wire?
1 Answer
Hi Johnnie:

All of our CL3 rated speaker wire has a UV treatment added to the outer jacket so it should not be a problem. Usually, we recommend 12 gauge for Subwoofers and 14 gauge for an upgrade from 16 gauge. The 16 gauge works best when terminating into our Speaker Selectors and indoor Volume Controls. Make sure your speakers will accept up to 12 Gauge. The rule of thumb for us is 16 gauge for runs up to 80 feet and 14 gauge for 81 to 200 feet. And 12 above that. Also 14 gauge for subs up to 50 feet and 12 AWG above that. It is never a bad thing running bigger wire.

m going to purchase the Sonance speaker system which includes 8 speakers, one subwoofer and amp. The distance of speaker wire I need is approximately 170 feet (one straight run). Can I use 14/4 for my wire? If not, what do you suggest? Thanks Matt
1 Answer
Hi Matt: Sonance recommends 14-4, you need a 4 conductor cable based upon their installation video. We have a 12 gauge, but it is limited to 2 conductors. We usually recommend 16 gauge for 0 to 80 feet, 14 gauge 81 to 200 feet. 12 Gauge longer than 200 feet. If you are connecting a subwoofer/low frequency only; 1 to 50 ft 14 gauge and above 50 feet; 12 gauge. TL/5474

1 Answer
HI Josh: They tell me the official diameter of the 12/2 is 5/8". Use that number as you reference. TL/4954

March 2, 2018
Is the strand count of 168 per each wire (Black is 168 & Red is 168) or is this the combined strand count for both (84 strands for Black & 84 strands for Red)?
1 Answer
Hi Darrell: The strand count listed typically refers to a single conductor which may have individual bundles like 168 may be 8 bundles of 21 conductors each. The multi conductor also make the cable more flexible and easier to install and work with. TL/4828

is a REAL dumb question for you guys. what does the CL3 mean?
1 Answer
HI Dan: CL3 is the rating of the outer jacket. It means it is is fire retardant and can be used in side the wall when connecting In-wall or In-ceiling speakers. So when you run the wire in the walls through the different stud bays and there is a fire the jacket will not burn and spread the fire inside the wall. It will just melt. It will also not give out any toxic fumes either when it melts. The FT4 rating is the Canadian equivalent. The CL3/FT4 rating is good for all residential and most commercial applications as well. It can not be used inside an heat or cooling duct in a commercial building. For that you would need a plenum or FT6 rated jacket. If you were using non CL3 rated jacketed cable on your home and had a inspector look at it he would make you remove it from the wall. TL/4070
