Well I've compared them ....same amp same box the AQ's were 1.5db down from the DD's...plus I've never blown a DD on a 1000 rms...or even 1500rms...the AQ couldn't handle 1000rms without sounding like it was gonna come apart....assembly line crap don't compare to an individual hand built speaker that has to pass several test before it is packaged and leaves the company...If it don't pass it is redone............but waste your money and learn or spend a few more dollars and do it right the first time...DD ...FTW ....
