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.

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?

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.

Very Good Subwoofer Cables
These are excellent subwoofer cables for the price, and you can notice an improvement in sound with these. One of my cables broke, and I was using a cheap cable until I could get a replacement. The very low end bass was rattled and wrong with the volume turned up. Once I subbed in one of these cables, the bass was great again. I don't think I need, or almost anyone else needs, to pay more for bass cables. I think these get me to peak performance for my sound systems.

Quite Satisfied
Onix series digital coax AV RCA subwoofer cable appears sturdy, well built, especially for the price. It fits tightly to connectors on both the subwoofer (Marin LoganDepth) and amp Pioneer Elite 7.2 ch surround sound receiver.
