they are the best car speakers that ive heard, i heard the in himmels van at the finals and his van was the best sounding one at the finals that i heard. i also have them on my display in .75 cubic ft vented boxes and they sound great. i always have a tough time trying to put into words the differences between sopekaers because there is so many other factors that can influence their sound, room etc. did you listen to mickey brones car at the finals with me? i would say that his eclipse was a close 2nd best sounding car that i listened to and he used the focal utopia mid with berylium(sp) tweeter, whatever that means, if anything
