Pioneer DM 40

I am assuming they will do what they are supposed to. It being Pioneer you do pay for the brand name. A set of 6″ KRKs will cost you roughly the same as the 4″ DM40s. It’s a personal choice, I have KRK 5″ currently and if they have to be replaced I will go 6″, because the low end is just a bit lacking. This will be more the smaller the speaker. So the 4″ will have even less bass.
