Shielded Speaker Wire 12AWG

In my opinion and experience shielded speaker cables restrict dynamics! My speaker cables are DIY, the positive and negative are tightly twisted together, no shielding and very short @ 12'' long. Cable material consist of,12 AWG Orange and black Mil-Spec M22759/11 (PTFE) Stranded Silver Plated copper, they look similar to this when finished. Both amp and speaker ends are bare wire. For in the what it's worth category, short speaker cables helps to minimize EMI interference, also try to keep power cords away from speaker cables. 😎

I agree with others - there is no need to use shielded speaker cables.

Firstly, they carry huge signals compared with interconnects of phono cables, so any RFI will be miniscule in effect.

Secondly, because a speaker cable is a pair of wire bundles, what  affects one bundle pretty much affects the other in the opposite way - this cancellation effect is crucial for very high speed cables like ethernet, which mainly uses unshielded twisted pairs these days.

Thirdly, adding a shield will increase the capacitance of the cable, almost always for the worst.

Speaker cables may benefit from being gently twisted but most often the two conductors will also be separated by about an inch.

Similar arguments apply to balanced interconnects.  Balance is good because it increases the signal to noise ratio.  Shielding is debatable.

If cables must cross other cables, try to do this at right angles to minimise interference.

I'd caution you about centre speakers, but it is off-subject!  Nevertheless, have a good look at this Discover the Surprising Flaw in Center Channel Speakers

I appreciate all the great guidance and the video about center channel speakers. I am leaning towards the  T-14 Speaker Cable - DH Labs Silver Sonic https://share.google/Wo4rwTXnxtRYcwcu0

Hello cgbgregg, You can also consider Iconoclast spkr cables. Due to room layout, I have 25' runs of Iconoclast TPC. Immediately upon listening to them, my boss who is always concerned about my audio expenses, smiled enthusiastically (!). The design inherently rejects noise, but the point is that even w my long run, they sound clear, revealing, enlarged soundstage, no noise. If your length is more reasonable than mine, they will send you a pair with a 30+ day return. Bob Howard at Iconoclast was very knowledgeable and thoughtful (850-860-0940). I did a ton of research before ordering; No way I am returning mine.   

Blue Jeans Cable sells Belden 10AWG stranded cable. That's what I use.
