I won these in an ebay auction and they are in a process of being shipped to me. Something about them caught my eye. The seller says they are made by a company called DPI and that he got them at a garage sale. I could not find any information about them at all online. Each box is approximately 8.5 inches wide, 8 inches deep, and 20 inches tall. Each tower has two 6.5 inch speakers and a Titanium Super Bullet Tweeter. Each speaker weighs about 18 pounds as per seller. Thank you everyone! I am updating this post. I was finally able to identify the tweeters, it looks like they are cheap pyramid tweeters sold on amazon. So, that's not great news. I still can't identify the speakers though. Please help!
