coax is 75ohm just like dedicated subwoofer interconnects.

Is it ok to use with this with 3k subwoofers like paradigm sub 15? Is it quad shield?

Is output from receiver to subwoofer analog or digital if these devices allow to use this cable to connect?

Subwoofer cables and other RCA audio interconnects have no defined characteristic impedance. OTOH, 75ohm coax will work.

Any coax will do.
It is analog regardless of the cable used.

That is not what I've read over the years. As I understand it -- it should be:
75 ohm for subwoofer interconnects (just like yellow video composite interconnects as well as digital "coax" digital connections)
50 ohm is standard for L/R (black and red interconnects)

Monoprice cables are really quite high quality. It does not matter the cost of your subs - the cables will more than suffice as will your coax...Coax is likely better shielded than some subwoofer cables -- I've read that many recommend using coax for long runs anyway.

Thanks for quick reply. I am trying to make sure I am exploiting full potential of high end subwoofer with 8 dollars cable.

If I want to go for brand names, they are not even available in stores for 50 feet length. Moreover, price is is three digits.

It seems what you pay is what you get does not apply to any of the cables.

No analog RCA signal cables (be they full-range or sub-woofer) need to be labeled 75 Ohm. Digital cables are a different ball-game.

There is so much nonsense in the cable business, it is not surprising. I would love for you to show me a technical reference for it. What people sell is what they can convince people to buy.

Now I'm curious...I do understand your point that if the source output and input aren't 50 or 75 ohm, then it doesn't matter what the cable is --- especially if the source or input have such vastly different resistance measurements.
snake oil abounds in this hobby...
