I had white van speakers for a while in college. Acoustic Monitor Digital V or something like that. They were pretty terrible, but I also had a pair of Realistic Mach Ones that were at least decent, so the white vans didn't get a lot of play. I never knew about the white van scam until years later, i had picked them up for $20 at a yard sale. Prior to me learning about that, I had given them to a girlfriend, and now I feel really bad because she was a really good person, and didn't deserve such terrible speakers. I think she said she threw them out in a move.
All I remember about their sound is that everything sounded indistinct on them, and one of the cabinets rattled.
