hdc3's

I am selling 2 HDC3.118s, they are in almost perfect condition, the only reason they aren't in perfect condition is because they are used, they have always been run on clean power by a soundqubed 4.5k, i am trying to get 300 for each, thank you! I am sorry, i'm a noob at this so i'm confused on...

Are the new ones still pounding hard after china parts? Should I get a Bl 15 or a DDC3 15 for a daily driver but for high sq and spl. Other brands?
