A little costly but worth it if you want great sound
AudioControl DQDX - Black/Blue
6 Channel Performance Digital Signal Processor with EQ, Crossover and Signal Delay plus 5-year warranty*!
For over two decades, AudioControl has been designing and manufacturing award-winning autosound products at our factory located in the rainforests of the Pacific Northwest. During this period, countless sound-off winning contestants have chosen AudioControl products to give them the competitive edge. "Can you really win without AudioControl", was part of an article written commenting on competition winning systems. Nothing sounds better than an awesome recording played back on a kickbutt system. Unfortunately, the acoustics of your vehicle can take away from your systems performance. While AudioControl products do not change the laws of physics (although they act like they do), autosound enthusiasts have long known that AudioControl products "make good stereo sound better"
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.
Because of speaker placement limitations and the seating positions in a car, it is almost always the case that the driver of the vehicle is in an incorrect acoustic alignment. This exists because the driver is close to the left side speakers and further away from the right side speakers. Thus, the sound from the left side arrives much sooner than the right side. By delaying the appropriate speakers for just a few milliseconds, the DQ-61 is able to allow the signal to arrive at the same time putting the driver in perfect acoustical alignment.
Equalization for Maximum Control and Performance:
Like all of AudioControl's high performance signal processors, the DQ-61 is designed to offer maximum audio performance and control. All six output channels are equipped with highly accurate graphic equalization filters. This equalization allows for the taming of the most demanding car acoustical challenges or correction of factory radio response curves.
24 dB / octave Linkwitz-Riley crossover:
The AudioControl DQDX uses a 24 dB / octave Linkwitz-Riley alignment crossover to separate the bass frequencies from the midrange and high frequencies. The crossover in the DQDX gives you a flat response without any peak or dip around the crossover frequency. In addition, the 24dB crossover makes the transition without the phase irregularities you get in most other configurations. The crossover selector is exact so it completely eliminates the guess work during the installation.
High Voltage Line Driver:
The high voltage, low impedance outputs make a huge difference in how your system's amplifiers will perform. First, the high voltage pre-out means your amplifier can reach full power without having to turn up the amplifier's input gain controls. This means you get more volume with less noise and less distortion. At AudioControl they are all about "Making Good Sound Great" and with the built in Line Driver in the DQDX you will be sending the best possible quality signal into your amplifiers.

Everything I read about for high quality sound this does. I thought my system was clean and clear but this makes it better. Cuts distortion increases output adjusts for acoustic faults.

The sound processor helped my system. Made it better. It instantly sounded cleaner and clearer. It’s possible using an EQ could give similar results but the unit is almost magic. I found using filters on my amps or head killes some of the dynamics so I end up turning them off but the crossover/filter in this must be exceptionally better. Using the sound app I made changes I may not have considered that improved clarity and removed distortion. My system is louder. The input output controls gave me more bass and helped balance two 15” MTX on different amps. The delay really moves the imaging and moves the subs when is crazy. It was fantastic until I started the car and I had alternator noises for the first time in this system. I moved the internal jumpers and removed it but there is some rumble way down and I had noise once trying to split to different amps. I since added a few filters. It’s hard to accept that mid bass is the downfall of most systems I have tried to build a system to optimize mid bass but the graphs are correct and the processor can dial everything in. Sonic had a nice price and usual there by Thursday shipping but more importantly had it available to consider. Looking for places to install equipment is tough but this worked out well and gives a professional look and sound.
