Ok that was interesting reading. Thanks for the input. So to add I did not pay retail and bought them new off a friend for half of retail. Just finished installing them and I'm impressed with it. Yes I'm no audiophile, but just running off my stock system and it sounds great already. Noticed alot of the same music I listen too had notes I never heard before. I will be adding a amp to them soon and hopefully reach its potential. I do like the convertible solution of being able to remove the tweeter out. Wish they were beefier though would be my only complaint. Going to do some more listening...
