Does this end tighten down onto the female RCA plug? Like a screw/compression fitting?
A shopper
on Jun 1, 2017
BEST ANSWER: Thank you for your question. It will be like a standard RCA connection. Once plugged into the female RCA plug the outer conductor will be a little tight fitting over the female RCA plug. That way it will ensure that it has a solid connection. It will not require any turning to connect it. I hope this helps.

Yes, you are correct, the connectors can be tightened-up to form a compression fitting over the female RCA Jack. In my opinion, this is one of the most significant features about this cable, yet it's not even mentioned in the product description! (hint hint). The jacks are of excellent quality (machined metal, with gold plated connectors), and furthermore, the casing can either be tightened by hand, or tightened by wrench for a very strong, reliable cable plug to RCA jack "grip" - perfect for a "permanent" installation.

BEST ANSWER: Thank you for your question.
As long as your turntable has RCA connections you can use this to connect the two devices together.

If this is a cable pair, do they meet in the middle, or is it two completely separate cables? If they're separate it'd be cheaper to just buy two of the same length of the Monoprice Onix Series Digital Coaxial Audio/Video RCA cables which are in all appearances identical.

There appears to be a screw hole on each plug. What does it do? My cable's plus's shell is loose, is it because of the screw is missing? What type of screw is that?

How stiff is this? Is it the same as the subwoofer cables that have no nylon braid?

Great cables!
Great quality cables! Run three separate cables to three subs, ranging from 15ft to 50ft. No difference in performance.

Great product at a great price.
I purchased a Sub cable from Best Buy. It was $20. It did the job. I was waiting until I got this cable from Monoprice. This cable I purchased from Monoprice was $13. Its much nicer quality cable and connectors. Love the fit and finish. I might be able to return my other cable form Best Buy.

Great cable!
I got this for my subwoofer. It is a nice, hefty cable. The connection is firm and secure. Fit and finish is outstanding, and it sounds great. I couldn't be happier!

Great Subwoofer Cables!
I decided to replace some really old cables with these. I can actually hear a big difference in how my subs sound now. Low end bass is deep and full. I can feel the bass hit me during gaming and movies. Very satisfied with purchase.
