well the cmx use a titan type of metal compound tweeter, where as i think germs use a silk / cotton combination for their tweet. also germs have a better crossover for adjusting the set. IMO i would actually take the cmx's over the germs because i like the metal tweeter, and it not harsh, but imo it fits my taste. Dont get me wrong to you ur ears might have an orgasm when they hear the silk tweets. but for 435 - 450 i think the cmx are better at a 320ish range
