How do you tell negative from positive speaker wires?
A shopper
on Dec 24, 2022
BEST ANSWER: There is no polarity difference on this type of wire. The wires are neutral conductors. The picture is misleading. Only one wire has a colored line or lettering, usually blue, grey, black or red--doesn't matter. I consistently use the colored side as positive.

Wire does not have a polarity. Whichever wire you connect to a positive terminal, match it to a positive terminal on the other end. One wire clearly has a blue line on it to help you determine one strand from the other.

One conductor is marked with a colored stripe for the length of the wire. Just be consistent with polarity on both ends to ensure speakers are in phase.

Does 2747 wire have a direction of flow? - The wire I am replacing has arrows indicating which end hooks to the amp and which end to the speakers. I have always assumed it had lower impedance in one direction vrs the other.
A shopper
on Oct 30, 2018
BEST ANSWER: Copper and other wires are non-directional. The only thing that might have been directional in your past experience was the type of connectors or plugs on the ends of pre-made connecting cables. This is plain wire you cut to length and install your own connector plugs or strip the ends for bare wire connection.

Which of these work better to make my own biwire speaker cable?
A shopper

Monoprice Speaker Wire, Oxygen-Free CL2 Rated, 2-Conductor, 12AWG, 50ft
Monoprice Speaker Wire, CMP Rated, 4-Conductor, 12AWG, 100ft, Black
BEST ANSWER: I used the 12 gauge O2 free cable to drive my 7 driver, 4 ohm, Legacy Audio towers. plus the center. They are plenty efficient and the Outlaw Audio amp has plenty of power to drive them so I did not feel the need to bi-amp them. The cable is high quality and priced way below anything else close. I ran 14 gauge for the 8 surrounds and Atmos speakers too.. The sheath was almost too thick for my cable trays. Again, very high quality.

Depends on what you want to use it for. If you need plenum rated cable, then the Nimbus is for you. If you intend on laying the speaker wire on the floor, the choice series is perfectly fine cable. The Nimbus can carry multiple pairs of wire, thus making the cabling in a ceiling or under the floor easier, no need to do two or more cable runs. I cannot comment about the effect of crosstalk on longer runs.

If I'm running 12 AWG CL-2 wire in my walls, should I stick with the same cable from my binding post outlet from the wall to my speaker? Or would there be a problem to use this wire from the wall to the speakers? I think this wire would stand out less than the bright white sheathing. Thanks for any insight you have.
A shopper
on Feb 28, 2018
BEST ANSWER: The best solution is to keep the speaker cable from wall exit to speaker jack hidden.... don't leave too much extra wire coming out of the wall (but make sure you can connect it to speaker easily and enable later speaker movement/adjustments that you expect). Make the wire exit the wall so it is least visible from most common sitting location in the room. Other options include painting or wrapping the speaker wire in tape to color match to the wall. Check for paint that adheres to vinyl, or use colored electrical tape or shrink tubing. Good luck!

BEST ANSWER: I don't think this particular wire would be suited for outdoor use, but it might work. The only reason is because of the coating. It's thick and not cheap by any means, but I don't know how it would hold up in the long run when exposed to moisture. I'm using them for several home theater speakers as well as a desktop 2 channel setup. My setup would be considered somewhat high end', just for reference and they work great. I would contact Monoprice directly just to be sure. Hope this helps and good luck!

What's the difference between the "enhanced loud" and the "choice series" copper wire?
A shopper
on May 8, 2017
Monoprice Speaker Wire, Oxygen-Free CL2 Rated, 2-Conductor, 12AWG, 50ft
Monoprice Speaker Wire, Enhanced Loud Oxygen-Free, No Logo, CL2 Rated, 12AWG, 100ft
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.

BEST ANSWER: I can’t give you a 100% certain answer, but because this is not sufficient for in wall I would assume you shouldn’t technically put it under carpet either. It would most likely be fine, but I would probably opt for the wiring that is CL-2 rated instead. It has an extra jacketing around it that helps protect the wire and prevent fires.

No complaints, Very satisfied
The jacket stripped as well as expected. The blue stripe is easy to see. The wire is stiff enough that it's easy to lay out in a straight line without it wanting to go all over the place; yet it's pliable enough for tight bends without having to struggle with it. And it successfully transmits the signal to my speakers without sounding worse than the old speaker wire I bought 40 years ago. What else is there? Time will tell whether any longer-term issues, like corrosion, arise. In the meantime, I'm very satisfied.
