First off the k150 and 250 series heads have a slant front to them, the K 200 series do not, nor are they as deep as the k150 and 250 series heads.
The guitar and bass heads in the K150 series use a cabinet that is not as wide as the 250 series, however since the k150 series PA are wider these then use the wider 250 cabinet.
If you go and look in this site's literature section you will see what I have replied to you about.
