Is a 50ft RCA cable to connect a subwoofer to receiver too long?

I bought my first subwoofer ever (Monolith 10 THX), and because of the space issues, I'm not placing the sub next to the TV spand, and so I've bought a 50ft RCA CL2 cable, without realizing that it could be a limit restriction. Can any confirm that a 50ft RCA cable to connect the sub to receiver is OK?

The reason I bought it long was to run it around the door frame, instead under the carpet.

This is the one I've bought: Monoprice 50ft High-quality Coaxial Audio/Video RCA CL2 Rated Cable - RG6/U 75ohm (for S/PDIF, Digital Coax, Subwoofer & Composite Video)

Thanks,

I'm fairly certain I have the 35 foot version of this (mine is several years old I think) and it works perfectly with no issues whatsoever. You'll be fine. It's a very nice shielded cable.

The longest cable I've used is a 25' one https://www.amazon.com/Mediabridge-U...s%2C137&sr=8-5

The Monoprice one looks similar. The Mediabridge has a CCS (copper clad steel) core. (That's about as cheap as things get.) Its original use was for radio frequencies, but it works well as a subwoofer cable. Its shielding characteristics are good.

The major difference among coaxial cable is capacitance. I don't know which cable you're using, but the two series that specify a capacitance list 22 pF/foot. That's good.

That cable will work fine. The main issue that “makes or breaks” long unbalanced cables is shielding. Coax shielding is as good as it gets – typically 100% or close – because it’s double-shielded, both braided and foil. The only downside to coax is that it’s typically stiff and unwieldy.

As noted as long as it's a high quality cable with good shielding you should be okay. RG6 coax should work well. I have custom 53ft and 65ft runs from Blue Jeans Cable (Belden 1505F) that works fine. The main issue with long runs is running into ground loops and there are ways to deal with that if it occurs.
