This is a Carvin Red Eye Bass System 2-Cabinet Set, consisting of an RL118 an RL410T cabinet. As the model names suggest, they are a 1x18 cabinet and a 4x10 with Tweeter cabinet. The speakers are in excellent condition. I used Carvin for many years because of their superior, warm, unmuddied sound, and I dont know how they do it, but these cabinets are very light weight, while still having wonderful resonance They come with their casters and a set of speaker cables.
