I will go with EW, MB Quart has been around for a long time, but I have heard there stuff and I have JL in my car. I personally love JL, everything that they ever have made has been top of the line. I ran a set of JLs in the front with a 150x2 PPI amp when I went to competiton in tulsa. I had no probelms with front staging I love them to death. I dont remember what I got them for because I get everything at cost because I have sponsers. So In my opition I would go with the JLs everyday.
