zog Posted September 17, 2023 Posted September 17, 2023 Further Information: These speakers look OK but sounded very thin. I have not performed any mods to them. IMHO nothing special except there was a whole DIY mod thing about them ages ago. Now I see the pics I made they are a bit dusty, but have been stored in a box with some padding since I purchased them and not used. I tested them when I purchased them, they worked. I have not tested them since. There are a range of improvement projects documented "on the web" for upgrading the cabinet and crossovers for those who want to play with a DIY audio project. I got them on ebay at a good price, then got obsessed with waveguides and they have basically been gathering dust in my garage ever since. https://web.archive.org/web/20160319131515/http://gr-research.com/insigniaupgrade.aspx
