i havent heard them but i i was listening to the 5 way and the 2 way rev series 6x9 and the 5 way sounded better even though the rev one is more expensive and i heard alot of good things abt rev series being better then regular blue n silver cone ones but when i tried them at a local car audio store 5 way was better but since ur looking for 6.5 inch u should try the 4 way one and rev 2 way 6.5 coaxial at some car audio store before buying
