Cable with Neutrik Speakon connector


I recently acquired a REL Strata iii.  It is awesome with my Acoustic Zen Adagios.  However, I would like to find an upgraded cable with the Neutrik Speakon connector.  Any suggestions where I can find one?  Thanks.

Signal Cable is advertising REL cable with Speakon connector for $90. Look up REL in search function.
I have tried the Signal cable with ny Strata iii. There was a great improvement over the stock REL cable. I since have upgraded to the Synergistic Research cable, better than the Signal. But for the money the Signal is very good. And Frank in a true gentleman to work with.
If you have a cable you like, this is a very easy DIY project. I bought my REL sub used and the seller neglected to include the cable. Piece of cake to build one.
I had a Signal Cable one but it came apart; I now use 2 made by an Audiogon member who use to advertise on here; they are considerably better. I will try to find his name.
Neutrik Speakon plugs are very cool...been using them on pro gear for years. I did find an angled Speakon plug that is great for my REL (less stress on everything) and I had fun making the cables...much less expensive that way...shrink wrap tubes galore, and, weirdly, the plugs are made in Liechtenstein!
I have a Nordost Baseline made to Rel spec. Huge improvement over the stock cable. If memory serves me there was a $35 upcharge to make it to Rel spec a couple of years ago.
Speakon connectors are very easy to work with. They have set screw type internal terminations and come with two sizes of inserts to use as strain relief. I just made two different umbilical DC power cables with Speakon connectors to connect an outboard power supply to a preamp. For one cable I used bulk power cable and for the other I used bulk IC cable. These are terminated with Speakons at both ends.

I assume the REL comes with a Speakon input? If you know what cable you want to use, you could easily reterminate it with a Speakon connector, which is easily (and inexpensively) available from Parts Express. If you want to try a variety of different cables with your new sub, you could consider wiring up a Speakon connector to some short hook-up wires and then terminate those to a standard rca connector input (I assume you are connecting a standard low level sub cable?). An inexpensive rca input connector should also be available from Parts Express. Using that "adaptor" set-up, you could try a variety of sub cables that have standard terminations until you zero in on what you want, and then reterminate the REL end of that cable directly to a Speakon connector. I would try something like that before paying a bunch of money to have someone make a cable that I haven't heard before, or to pay to have someone reterminate cables for me.
