Wow......never thought I'd initiate a speaker discussion. My DQ were bought new by an electrical engineer. He had moved into a retirement home and didn't have the room for them. I saw them on the FB marketplace...$375. He said they didn't get much use. Woofers were re-foamed. I think considering an electrical engineer bought them new, then that speaks for something. Other than the re-foam, they are 100% stock. As for me, they sound spectacular......now, I'll just keep on perusing this forum. Great info.....most of it a little over my head. But I've also learned a ton here! Happy Trolling!
