Great heavy cable for sub-woofer that I have had no issues with.  I have had other cables from BlueRigger and they all seam very high quality and I have had not issues with them.

I used this cable to go from a media closet to the back of the room for a subwoofer and it worked great.

I needed high quality, durable, shielded cable to extend the reach of system audio running from my audio recording computer (system sounds, internet audio/video, etc.)

This cable is perfect.  It is super thick, but still extremely supple (they have the feel of EPDM rubber).  There are actually two visible cables (left/right) molded together, not just a single combined run.

I probably wouldn't use this to extend the reach of a pair of earbuds, but they are great for the semi-permanent solution to extending the reach of my computer speakers in the studio.

My advice.  Buy 2 of these great cables and a 2nd sub-woofer.  Place them far left and right in your listening field and you're in 'audio heaven'.

This cable is amazing there really isn't a difference from another gold plated cable like this one but this cable is very heavy duty and well worth it.

This is some ridiculously thick speaker cable (I actually mean that in a good way). The only issue I ran into is that it was really tough to insert this properly into the speaker terminals on the back of my Yamaha receiver. I'm assuming that this is probably an issue for most entry level receivers and they aren't really designed for really thick wire, so it's hard to complain that these wires are basically "too good".

Given the above installation problem, I would probably buy 16 gauge next time, but I really do like this wire for what it's worth and the audio quality is great.

I purchased this cable to replace some from that other big company and this cable is much heavier so I am certain that it will hold up through pretty much anything that a typical home environment would throw at it.  It weighs two to three times that of the other cable and is real copper for those wondering.  Buy it and see for yourself.  Shipping was fast as well (direct from KnuKonceptz).  Buy the speaker wire pants and you will have a professional looking cable for a fraction of the cost.

I have a turntable and phono preamp in one room and my main amp in another.  I seriously wanted to avoid hum or interference. I ran this under my house and the result has been excellent. This cable is seriously heavy and well armored.

If you have to do a long audio cable run and you're serious about getting good results, I highly recommend this cable.

These power cables work fine and seem heavy-duty.  I was a little worried that they might be too stiff, but that isn't a problem.  I'm using them to plug into the bottom of a pair of Definitive Technology Mythos ST large tower speakers.  The cables come out the bottoms of the speakers, bend under the granite bases, and go up to power strips located on top of an entertainment center.  The extra length (compared with the original cables) lets me move the speakers around freely.

It is heavier and a larger cable than I expected. Here are some more words. One two three four five

Using these from a receiver in an electronics closet to home audio panel, then from a remote panel to a sub-woofer.  High quality cable with solid connection.  Flexible without feeling flimsy.  Does what I need with a third of the competitor price.  These were connected together like you would want for Left and Right audio, but easily separated (without damaging the insulation) by just gently pulling apart-no knife required. Sub woofer performing perfectly.

Excellent HEAVY made cable.  No static or noise on my wife's classroom RedCat like the old cable the school used.

Used this cable to hook up a subwoofer to a power amplifer and it works great, easy to take apart and switch the wires around if needed. The markings on the terminals are kind of hard to see unless you look really close, but otherwise its great.

This cable is similar in thickness to instrument cables, very thick.  The audio quality is clean and interference has not been an issue for me.  The only thing that could be a problem for some people, as mentioned by others, is that the cable itself is also very heavy so extra care must be taken to avoid damaging the audio jack it is plugged into.

Just installed this cable on my new BIC PL-200 sub.  Sub sounds great.  Cable has a feel of strength and durability to it without being too stiff.

I am using these under a pair of high quality full range speakers, each of which contain 3 12" woofers. For years I went with the approach of spikes to couple the speaker to the floor with mixed results. After having excellent success with Auralex foam under monitor speakers, I decided that maybe decoupling my large speakers would work well. Because of my speakers large size I decided to go with the full size sub dudes. Auralex rates them at 300 lbs. and my speakers weigh well over 100 lbs. each and stand over 5' tall and they are completely stable on the platforms. They have also been setup for several months and I see no evidence the foam is settling or compressing. As for their performance, they do an excellent job of isolating the floor and furniture from vibration. In addition low frequencies are rendered clearly with none of the "muddiness" that large woofers can often produce. I was so impressed with them I purchased an additional unit for my home theater subwoofer and 2 more sub dude II's for a smaller pair of full range speakers.

I received this cable on August 25, 2015.  I had purchased it for use in a hifi system along with a Wharfedale 8" subwoofer.  I had read good things, but I was still surprised by the quality of this cable when it arrived.  I also use BlueRigger HDMI cables, and I am very happy with those, so I bought this as well.  It is a very thick, dual shielded cable, and the ends are gold plated and fit snugly with no play.  It was exactly what I needed.  Bass was crisp and clear, no hum or interference.  I ended up replacing this with a MediaBridge cable because I discovered that if I used a cable with a split mono lead, I could get a bit more input level and a noticeable gain in output.  I wish that BlueRigger made a split mono version.  I briefly considered buying a small splitter adapter and a second one of these because of how nice it is, but the cost would have been too high.  If your subwoofer uses a crossover that only requires a single RCA connection, then this is the cable to get.  If you can get a bit more level using a splitter, or a split mono cable, then go that route because there is a noticeable difference.

Pros:
-Thick, high quality cable
-Gold plated ends
-Snug fitting
-No hum or interference (dual shielded)

Cons:
-Not offered in a split mono version

All in all, I will be using more BlueRigger products in the future and I look forward to seeing their line expand. I rate this cable at 5/5 stars and highly recommend BlueRigger products.  For the cost vs. quality this is easily one of the best brands on Amazon.
