I wish these cables always come with the shown Neutrik ends, and since I bought a total of 9 of these, only about 1/3 come with the cool ends. The others come with workmanlike ends without pizzazz. At 50ft, these are perfect for 15" speakers, and at 100ft, I would keep them away from anything less than10" because the capacitance is a big killjoy. I run 18ga to my 10s and the 12ga to my 15s and 12s at up to 100ft and the sound is similar to me than running all of them at 25ft with the same gauges. Don't believe the hype that you need powered speakers to get awesome sound - just manage your wire gauge and you are golden.This thing is 12 gauge. It's effing huge! Durable and neutrik connectors are solid. Only complaint would be if you are using an amp in a home, cannot put cabinet too close to wall. Like need about 6-8" of clearance from wall. Sticks out quite far but thick cable too, you don't want to bend the cable, you can but it would affect signal a little, but still, even if you bend wire, it still needs the clearance from wall.These cables are serious business!! They are about at LEAST a cm thick! Nothing is cutting through these bad boys! They're solid and are well built inside. The shield is massive and provides a lot of protection. Nice lock in, too! I love these. Beefy is what I want if I want to protect and feel comfortable with my connection to my monitors (Tannoy 601a Reveal series). What an awesome purchase!Perfect. I had to replace the speaker cable for my amps because the jack had bent after a gig one night. These are great! I love the thick ends. They are better at securing the jack into place. These are the right babies for replacing amp gear! I've been gigging with mine for about a year now.So just a note. MAKE sure you know the length of the desired cable. Trying to guestimate the amount you need is lazy. actually bust out a measuring tape and check to make sure you always have the right amount of cable needed. That said, This product is legit! Ordered two 5 ft. 12 gauge 1/4in. speaker cables. Super HEAVY DUTY!!! works great!I bought this to connect a Kustom Defender 5H to an old Peavey 112SX cab used in the bedroom. The cable is heavier than I could have imagined and gives the impression it could handle a lot more abuse than I'll ever give it. I haven't heard any extra noises I could attribute to these cables; they are transparent.Holy Crap... this is thick cable. I haven't hooked it up yet, but definitely worth the price. Well made, properly over-moulded with shrink wrap, gold plated tip (the sleeve is not plated) on the 1/4" TIp/Sleeve connector. Make sure you have a few inches of clearance behind your conniptions, these suckers will stick out a bit.Awesome cables! Used in my Rokit KRK 6" monitors - The picture doesn't do this product justice - the connector is HUGE very reinforced and thick, durable, just a high quality cable.Just awesome
