Diki please dont try to make them more then they are, ....I have always said that the CM30's are great for small jobs nothing more or less....they fill MY Needs and sound Great in that situation. Why even say to put heavy Bass thru them they werent created for that? If that's what someone needs then when they try them they'll make a decision for their needs...if you need that much Bass add on a Sub also like cass does.....these are lightweight, small and powerful enough to do the job period.
