Here's the deal. The speaker is an Electro-voice LS215 Low frequency cabinet. It has 2 15" speakers in it. I've been using it with my Bass rig. I upgraded to a new cabinet, and I've had no luck finding any information online, whatsover. I'm going to sell it, and I'd like to know what year its from, and any other useful information. I have the feeling it is from the 70's or early 80's. I bought it very used about 7 years ago. It has a 70s look. Anyway, thats it. I hope someone can help I have never replaced anything, but it still sounds damn good. It is just waaay too big. (The new one is 2/3 the size and is matched perfectly to my bass head). I did email their customer support, twice. no response in the last few weeks. As for age/look, I live in new york city, and with all the strokes wannabes here, It will help me sell it for more.
