Awesome!

The following review is for a previous version (Stadium GTO 20M).

If your car has the room to fit these, they will absolutely transform your experience. It is truly jaw-dropping what these will add to the system. The singer's voice will be crazy elevated. Normally when you raise the mid EQ, you get a hollow sound which is nlterrible. These are so filling and dedicated, that you don't have to raise the EQ just to hear the singer's voice...it is just "there"...and VERY clear. These things will scream. Literally.
