Check out the CDT Selection of speakers at http://www.thezeb.com. They have a good selection of CDT components. They also have some MB Quart speakers but they arent well known for theyre midbass.
Polk/Momo are pretty good speakers, and have more midbass than most others. Although the components don't play as low as the coaxs. I think 50 Hz as compared to 43 Hz.
