The SMD QR-1 Quick Release Heavy Duty speaker box terminal cup is a great solution to 2 common problems. One being that most terminal cups are very wimpy! Not this one! Rather than a very thin injection molded unit like most others use, ours has a 1/2" body and 1/4" thick flange milled from 3/4" PVC, this product will never crack or deform under pressure. The terminals we use are made of nickel plated n52 neodymium magnets, sealed with SMD Sunflash. They will never move OR leak! 100% Guaranteed not to "vibrate off" from any vibration of any sort.
The next problem this product solves is of course, removability! If you live in a place you need to bring your box in at night, or perhaps to make room in the trunk for other items, now you can do it in a snap!
