My anonymous sources tell me that the CD D's are: Downweight- 1 - 16 = 51 17 - 32 = 50 33 - 45 = 49 46 - 61 = 48 62 - 75 = 47 76 - 88 = 46 Upweight should be a minimum of 18 in the bass and 20 elsewhere. These specs work well for B's also. I don't deal with smaller ones much. Conrad Hoffsommer Luther College
