We ship these sets out daily, so people have been figuring them out. They are very popular
I actually have these in 2 vehicles, they are excellent. The midbass is fantastic, and I mean fantastic, and quality of sound is awesome, by far the best sounding set of components per price I've heard. one vehicle is amped off the stock setup and the output on low wattage is incredible along with the fact the midbass increased drastically, the other vehicle is on a 150w per channel b2 Quattro. They get loud and retain a very nice balanced sound very well. The tweet is very smooth sounding as well and not harsh at all.
