i originally bought these cables as backups for the speakons we were using in the band since they were so cheap. when my main cables( more expensive i may add) lay down on us the SLL21510 became our main speakons. since then they have not been replaced and as far as i can see they wont be in the future. As with any cable of any price a certain degree of care must be taken when using and storing these cables but as long as you observe this kind of care they will work perfectly. lined up against more expensive speakon cables i have not noticed any degredation of sound quality or any outside hum or interference through my P.A
Overall Very Happy with the quality and price of this product!
