I'm pragmatic when it comes to cabling I don't care what Monster tries to tell you, cabling doesn't need to cost a million dollars or have gold plated connectors to make things sound "warm" and "musical." They conduct electricity for god's sake.
These cables get the job done for the right price, and it is surprisingly difficult to find suitable 12 ga wire for PA systems online. I split the 100's into a 75' and 25' cord using Neutrik NL2s on the freshly cut ends. The stock connectors seem just okay, I don't know if they'll resist impact, abrasion, or normal wear and tear as well as the genuine article, but they seem like they'll hold up well enough. Make sure the collar is screwed tight all the way up to the chuck/connector so they don't unscrew. Pretty much all of mine arrived loose - not a big deal, but worth mentioning. Only time will tell if they hold up, but they don't seem at risk of breaking right off the bat.
The wire itself is pretty robust, it's double insulated and molded ALL the way around the inside wires (which are themselves individually insulated of course), filling the gaps so there is no wiggle or twist in the wires.
I wouldn't hesitate to recommend these cables to anyone, as long as they keep a few spare NL2/NL4 plugs around!
I have several of this kind of cable from Monoprice, at different lengths...25' , 50' and 100'....they all have the super quality 12AWG wiring w/ great shielding but poor quality connectors. I had 2 of them break upon the first couple of uses. I quickly remedied that by purchasing the Neutrik NL4FX connectors. You can buy them from Fullcompass.com or get them off eBay for $4/connector.
With that combination, you can't beat the quality of the cable for the price,even after you replace the connectors.
PROS: Very nice shielding, thick sturdy cable for use on the road, wire conductors have been "tinned" for re-wiring purposes
CONS: Poor quality connectors......they are plastic and will break.
I can also say that I had had one intermittent connection. It was connecting to a coupler for extension reasons. The coupler was Neutrik brand from FullCompass. After flipping the coupler around, I no longer had an issue despite being coupled to another monoprice speakon cable. So I would say there may be a slight connector issue but for the most part they work fine.
I bought three 100' cables and one 50' cable to run audio for a permanent installation. After running all of the cables through conduit and getting everything setup, I wasn't getting audio. After jiggling the connectors on the amp and speakers, I was able to make audio come in and out. I ended up having to purchase higher quality Speakon connectors, and re-terminate them properly. I do not recommend these cables at all.
