I don't think many people would consider the Vandy's as a good rock speaker. I listen to rock & blues exclusively, I owned the Vandy 2Ci sigs, they were nice but too polite for rock. I also heated the cones up so bad one night the warning lights came on, not the best for a "rock" speaker. When I called Richard the next day he said I must have been listening at "drinking levels", which I was. I have used that term ever since & he was 100% correct. I loved the sound of the Vandy's & would own another pair but didn't find it to be the best match for my listening tastes.
I now have a pair of VSA VR4jr's & my friend has a pair of VR4's, they are definitely a dynamic speaker with some slam. They are nuetral & fast, they can reproduce the thunder of a live show or the delicacy of a single wind instrument if called for. Most of the time people recommend "lower end" speakers when people are looking to rock but I think it's a cop out. There are plenty of high end speakers with dynamics & slam, you just have to poke around.
