Why do you need Signal Delay (or an Equalizer for that matter)
Putting the driver in perfect acoustical alignment definitely has its challenges in a vehicle.
In home audio it is generally 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 manufacturers
has supplied us with. This usually created a whole slew of issues when you add amplifier
power, new speakers, and subwoofers. Which 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.
