Is this CCA or actual pure copper?

BEST ANSWER: This wire was sold as oxygen free copper not copper clad. I'm not knowledgeable about purity claims.

It doesn't say on package but looking at it with magnifying glass it looks like pure copper.Enter

What's the difference between the "enhanced loud" and the "choice series" copper wire?
A shopper
on May 8, 2017

Monoprice Speaker Wire, Enhanced Loud Oxygen-Free, No Logo, CL2 Rated, 12AWG, 100ft

Monoprice Speaker Wire, Oxygen-Free CL2 Rated, 2-Conductor, 12AWG, 50ft
BEST ANSWER: It appears the Loud series has a resistance of 7.2ohms/km. while the Choice series has a resistance of 5.69ohms/km. The resistance of the speaker wire run can be added to the impedance of a speaker. For shorter runs, not really significant. Not clear on why the Enhanced Loud would enhance bass more than the choice, if that is what the claim is.

You would have to to get a per foot impedance of each cable to be certain and it's not listed for either ... the only way a wire itself affects sound is by adding more resistance to the circuit which can change the response curve of a speaker, unless they somehow made the wire of even purer than the "99.95% purity copper" of the choice series or managed to fit more stands in the same AWG I don't see it being any different.
That said, IF it does have a lower impedance the difference would be insignificant at best (likely inaudible outside of soundproof lab conditions) The more important thing is to get a wire that is appropriately sized and up to any applicable codes for your application, like fire rated, and I would suggest oxygen-free pure copper, because clad aluminum will have a higher impedance and be more likely to change the sound.

Does it state or read anywhere on the body of the wire that is authentic oxygen free copper wire ?
A shopper
on Nov 3, 2018
BEST ANSWER: The cable carries a UL rating. The cable would not be UL compliant if it were anything other than Pure Bare Copper. Thanks for asking.

Is this speaker wire safe to route in ceiling/walls? What is the class? Is it UL listed?
Brandon V
on Aug 8, 2022
BEST ANSWER: I put the 12-guage, oxygen speaker wire right along where the wall and the floor meet for my stereo configuration, but since the wire says it is UL approved in the Monoprice specs, I cannot see why it would not be safe for behind wall/above ceiling installations.

Great
Just got my speaker wire from you and what a difference. I had 12 Guage speaker wire before but needed to upgrade and this did it.
I'm hearing all the sound that's suppose to come out of the speakers. Thanks!

Very good quality
Simple wire that?s clearly marked, very high quality. I use an auto stripper. I had to use the 10 gauge stripper section so it didn?t cut the wire. Very strong, a bit stiff but it allows it to be adjusted around the baseboard and keeps it shape. Couldn?t get a better wire for the price.

Love them, had monster wire and began to look for new speakers, once I got them connected and started playing music my wife came downstairs and asked did your new wires make my speakers sound like that? With a smile on my face told her yep everything sounds new, movies and all. Love them. Highly recommend them before buying new equipment.
