DQDX Digital signal processor with eq, crossover and signal delay
 
Putting the driver in perfect acoustical alignment definitely has its challenges in a vehicle.  In home audio it is generally pretty easy to just move a speaker forward or backward or to the left or to the right to help make sure you hear both speakers at the same time.  In a vehicle, we are typically stuck with the speaker locations that the vehicle manufactures has supplied us with.  This usually creates a whole slew if issues when you add amplifier power, new speakers, and subwoofers.  This is why signal delay and equalization are so critical.  Equalization helps match all your new components together so they sound great and signal delay helps all that great sound arrive at you, the driver at the same time!
 
Designed for maximum sound quality and enhanced audio performance, the DQDX is the latest AudioControl processor to incorporate Signal Delay. This process corrects for the varying speaker locations in the vehicle.
 
The AudioControl DQDX lets music enthusiasts truly “take control” of their sound and receive an amazing experience.
