[QUOTE="LosIsATool, post: 8397736, member: 632125"] Andy referring to the MS-8s lack of sub TA. Keep in mind how many awards this processor has. If you set time alignment manually with another processor, you measure from the speakers to the listening position. The sub is farthest away--let's say it's 5 feet away. Then, measure from the next one--probably the passenger mid in the bottom of the door, which is probably 4 feet away. The difference in the distance is 1 foot. So, you delay everything but the sub by one foot. Now, let's say that your crossover between your sub and your front speakers is 60Hz. A 60Hz wavelength is approximately 20 feet long. One wavelength is also 360 degrees. 1/20 of 360 is 18. The phase shift at the crossover frequency (which is all that matters) is 18 degrees. That doesn't contribute any cancellation nor does it affect the placement of bass sounds or the illusion of bass up front. Getting bass up front is simply about making sure that polarity of the sub is correct and the right EQ. You can simply swap the speaker wires and recalibrate with the microphone to determine which of these you prefer. [/QUOTE]
