I paid over $125 for orion 6.5 midrange and tweeter combo to put in he doors of my mustang along with buying a mids and high amp after i installed the orions in my mustang ,the sound quality wasnt there with the orion componets even after i hooked up the amp to them ,i saw a video of the ds18s on youtube so i purchased a set of the ds18s 6.5 and super tweeters installed them in the doors ,just on the head unit and the sound was amazing no need for a amp so i purchased another set for the rear deck in my mustang ,you can hear the mids and highs clearly even with the two 12 inch subs in the trunk .i have two trucks that are fiximg to have a set of ds18s in the doors of them real soon .great sound and price
