DIY Spekon Cable For Rel

I agree with @oberoniaomnia - trust REL and use the stock cable.

If this is a line level signal then 24 awg is quite typical and sufficient. If you don’t use the REL cable, I would recommended soldering SpeakON connectors to any reputable bulk shielded audio interconnect (Furutech, et al.) or bulk professional mic cable from the likes of Mogami, Gotham, or Belden. However, I seriously doubt you would ever discern a difference between those options and a cable from REL. Rabbit holes are usually a waste of time and money - I know because I have been down many of them.

Mostly I just need longer cables. I bought the subs used and the cables had been cut by the previous owner. I figure I may as well diy and get a better product at a better price. It is a very simple cable after all. Mostly just wondering how much shielding may make a difference. It seems it’s essentially an interconnect cable which are typically shielded I think.  There is a gentleman who sells nothing but mil-spec silver plated ptfe on eBay and he has some two and three wire shielded options.  This route would cost me about $50 and I think make a solid cable. That’s kind of what I’m leaning towards but like I said pretty amateur when it comes to wire.  

Mogami 3104 12awg quad cable + Neutrik NL4FX 4-Pole speakON cable connector.  Good LCR spec but not sure if you could hear the difference from the Rel stock cable though.

What I have found is that the speaker cable used from the amp to the sub via the speakon connector will affect the sound of your main speakers. Afterall the cables are connected to the same source (amp). So, they do interact.

So, choose wisely.

I have never owned a REL sub - these must be speaker cables.  My comments assumed line level cables.
