to be honest, ive never heard any other set of components besides the ones you can purchase at retail giants. these obviously blow those away.
they get very loud and the tweeter can definitely be bright if you leave it on the factory setting. I adjusted the tweeter down to -6db and it was just right.
i also have 5.25 Q's (the black ones not the tan like these) and i can easily tell the difference in midbass with the 6.5's. the crossover is much bigger also on these 6.5's.
