CDT Audio

I have been researching 4" component sets for quite some time now, and I have come to the conclusion that I would use one of the following brands:  MB Quart, Polk, or Infinity.  I would try Boston Acoustics, but their 4" midrange is actually a 4.5" midrange, and my install location in my door specifically requires a 4" midrange, no cutting and no exceptions.  To get the fullest front imaging possible, I have thought about a custom kickpanel for a 6.5" midbass.  I hadn't really seen any CDT stuff until recently, so I was wondering what experiences anyone has with this company.  At their website, they seem to brag an awful lot about their Eurosport series.

So, what do you (anyone out there) think about CDT 3-way components as opposed to MB Quart 3-way components?

Thanks
