I love the MK45's. I did a lot of research, and listened to a lot of videos before I purchased. And they sound so much better in person. The fit and finish is perfect. The big thing is do you run them with the reducers in or out. The sound is awesome with them out. But I think you lose a little low end torque with them out. So I'm running mine with them in right now. It still sounds good, and the low end torque is there.
