What is the difference in oxygen free cable? And you specify the gauge depends on the run, but doesn't gauge also depend on power of the amplifier? Thanks Doug
1 Answer
Hi Doug: We only offer our CL3 Rated speaker wire with Oxygen Free Copper. Two advantages, one being slightly better conductivity the second being protection from Corrosion. Regarding your second point, Bigger Gauge wire is typically better. Think of current traveling through the cable like water through a garden hose. The bigger the Garden hose, the more the water flows. We do recommend a minimum of 16 gauge up to 80 feet, 14 gauge up to 200 feet and 12 gauge above 200. That changes when running wire for subwoofers where we recommend a minimum of 14 gauge up to 50 feet and 12 gauge beyond that. Another factor you have to consider is what components you will be terminating to in your signal path. Mose Speaker Selectors and Volume Controls work the best with 16 gauge for their input/output connectors. The above recommendations pertain mostly to 4 and 8 ohm systems. 70Volt systems have no problem running longer lengths with smaller copper especially if the 70V amplifier has a subsonic or low pass filter. Hopefully, this helps. TL/5421

Hi. I will buy an ACE850 speakers for a home cinema using a video projector in my house, I will used in the wall, which is the better cable that you recommend me to buy? 12, 14, 16? What referenci? Thanks.
1 Answer
Hi Juan: The gauge sometimes is determined by what components you are using. We preach for full range speakers like the ACE850 from 1 to 80 feet use 16 gauge, 81 to 200 feet use 14 gauge and 200 feet and longer: 12 gauge. When we are talking about connecting a subwoofer than 1 to 50 feet: 14 gauge and 51 feet and longer: 12 gauge. But sometimes, when you are using speaker selector or volume, controls you may be restricted to 16 gauge which is the ideal fit for their connectors. But in your case where I am assuming you are connecting directly from the AVR to the speakers, 14 will work just fine. TL/5089

May 31, 2017
I have researched OSD 12 gauge two strand wire for some time now. I've talked to many experts in the sound design field who have told me that anything over 80 foot would require a 12 gauge wire for efficiency and less resistance. I am running about 85 to 115 feet of wire x4 channels in one location. (Across from main patio)(57ft x 14ft pergula) and a 40x10 by 40x8 L shaped main patio, in which my cabinet and equipment will be stationed. 4 speakers will be for sure with an optional 9th speaker possible. I live in Phoenix AZ, so yeah heat is a issue.... Now, should I run 14 gauge, or stick with 12? I am running an amp at about 115 watts per Channel x 7 with a later expansion of 2 more channels for a total of 9.2. Power amps might be added later and I'm definitely going to have a bunch of cooling fans.

Hi: Bigger is better, and also more expensive. It sounds like you are running speaker wire directly from your receiver to the speaker which is good. Typically when a set up includes speaker selectors or volume controls there is a limitation with the connector and what size wire it will accept. Most say up to 14 AWG but are made for 16 AWG. There is not a problem with most receivers or speaker terminals which accept up to 12 AWG. So if it is within in your budget 12 gauge is better than 14 gauge. The thing you want to avoid is running different Gauges in your single runs. Your chain is only as good as your weakest link. Think of the Wire as a garden hose, the larger the diameter the less resistance to the water flow amount. Same with current. TL/4399

How is this different than CL3 in wall rated speaker wire in terms of direct burial?
1 Answer
Hi MSP-N: The Speaker Wire we produce has a fire retardant CL3/FT4 rated outer jacket approved for In-wall/In-Ceiling applications. CL3 is for US and FT4 is the rating for Canada. The CL3/FT4 is approved for all residential and most commercial installations. You can not run it in a Heating/Cooling Duct. That would call for a plenum rated cable that is approved for all applications (but much more expensive and a stiffer jacket). It does not matter what you are running through the internal conductors just that if you were to have a fire in the wall the jacket would melt versus burn and not give off any toxic fumes. We also add a UV protection and increase the density of the jacket so it can be used for Direct Burial. I hope that helps TL/3748

Is this speaker cable shield so that it can be used in walls also?
1 Answer
Hi Andrew: You will note the Cable you are referring to is CL3/FT4 rated. This means the actual jacket material used is made with a fire retardant material. So if there is God forbid a fire in the walls, the jacket will not give off toxic fumes or burn so as to spread the fire in the wall. Worse case if the fire gets hot enough it will just melt. It has nothing to do with the current or signal run through the actual wire. Note these speaker wires are also twisted internally so each time there is a turn you get noise rejection eliminating the need to shield against external EMI or RF emitted noise. TL/3116

Sounds great but I need a very basic spec. Cable outside diameter? I have sections that have to go through conduit before the direct burial. Need the normal info to determine conduit fill code requirement. I find if difficult to believe this important information is not shown somewhere very easy to find. As I'm sure I'm just overlooking it. Thanks!

Hi Derek: Outside diameter is 1/4" or roughly 6.3 mm

Does the 12 gauge speaker wire come in a 4-conductor model?
1 Answer
Hello, No - our 12 gauge is only available as 2-conductor. We do have 14 gauge 4 conductor wire that is good for runs up to 200ft.

I want to put the cable in a pvc conduit to further protect it. How thick is the cable in diameter? Need to decide what size pvc to get. Thanks.
1 Answer
HI Kevin: I would typically recommend 1 1/2 inch PVC. Just in case you want to run more than one cable or if you would need to run a four conductor. Also you may want to consider run a pull string at the same time in case you want to add additional cables later. TL/3189

what cable labeling does the direct burial wire have on it? will it indicate that is is a direct burial wire to satisfy my local electrical inspector??
1 Answer
Hi Tim: This is the label on the outer jacket of our Speaker Wire Jazz audio 12/2 type CL3 75*C UV RES (UL) E241 235-F5 12/2 means 12 gauge, 2 conductor CL3 rated cable is approved for in-wall and In-ceiling for both Residential and Commercial applications. THis means it is fire retardant and will not burn if there were a fire inside the wall or ceiling. It would just melt and not emit any toxic fumes. The heavy duty PVC jacket is also UV resistant to resist other elements where it might be exposed above ground to the sun. (UL) E241 235-F5 is the factory listing UL approved. You must realize we are dealing with low voltage not high voltage electrical current. The next highest rated cable jacket for residential and commercial is plenum or FT6 (for Canada). This is if you were to place the cable in an air heating or cooling duct. We are pretty sure you will not have any problem having an issue with your electrical inspector. If your still concerned call them and give them the jacket text/numbers I gave you. TL/3177

April 15, 2012
please can you tell me if this cable or this one (16 Gauge 4-conductor Oxygen Free Speaker Cables 500ft are compatible with osd ls3 speakers and can you tell me what is the best amplifier compatible with these speakers ? best regards fabien sfez
1 Answer
Fabien, The ls3 can use either cable, up to 100 ft 16-2 would be fine, 100-200 ft a 14 gauge and after 200 ft you should use a 12 gauge wire. The best amplifier would be determined by how many of these LS3 speakers you would want to connect. One to two pair the AMP120 would work, three or more pairs you may want to step up to a AMP200 and add aspeaker selector. CL

how does this wire stand up to ocean salt air(condo near the ocean) and how does the sound quality compare to monster cable?
1 Answer
Hi Jim: Can you provide additional info? What are you connecting to (Speakers) and from (Amplifier/Receiver)? Are the cables going inside the wall, in the ground or hanging outside (to patio Speakers as an example)? Note the high strand count provides flexibility and passes more current when compared to Standard cables. These are 168 strands of 30 gauge copper. These are Oxegen Free (99.9% pure copper). TL
