I also thought about the break in period, but if you guys heard these you would know something was wrong. It's not just weak midbass or I'm not happy with the midbass, its NO midbass. So weird.
I have owned two sets of kickbass drivers (SLC and Profi's). Both of them had sorry midbass response initially, but after several hours of playing began to put quite a large smile on my face. That doesn't seem like its your problem though...very weird, hope you figure it out.
have you solved this problem yet? I am having the same problem with my Accord. Weak midbass from the focal k2p but doors are well deadened. No idea what's going on.
Kickbass drivers tend to sound hazy at first prior to break in. I wouldnt touch a thing until you've dialed in a good 10+ hours of listening. Then evaluate the situation.
