Assuming that processing is used to counteract the effects of PLD's and phase problems with dash mounted mids and tweets, would you still get a one seat wonder?

Hi Eddie,

It depends how big the PLD's are. The bigger the PLD's are, the more time alignment you need. The more time alignment you need, the more it becomes a "one-seat-wonder".

The problem isnt with the tweet (assuming its crossed over high).. PLD are in the mid freq's from about 300 to 4khz about..

Time alignment when used to adjust the PLD's from the left side to the right can only help one seat. Think about it. Lets say the driver finds center in the middle of the dash.. But the passanger finds it directly in front of him.. So you add alignment to the right side mid.. That in theory would move the center image for the passanger side closer to the center of the car.. But what about the drivers side? By moving the right side mid further away has now moved its center image to the left of center.

P.S. time alignment is really not made for aligning the left side speaker to the right side.. its made for aligning the speakers of the same channel, for example the left side mid to the right side tweet. There is tech-brief in the autosound-2000 techbriefs about how the patent holder for "time-alignment" was thinking about sueing car electronic manufactures for the improper use of the term/patent.

Oh, i have never heard a car with mids above the dash that i liked, and/or imaged properly from both seats.

"If you're implying that you can only have one or the other (high coherent stage or a system that sounds good from both seats)...I disagree with you."



Not at all gleepoy. I've had the chance to listen to some of the best sounding cars in the world. So I know that you CANhave good tonality and stage in the same car. Trouble is, it's hard to do. And by mounting your mids in the pillars I think you are making it harder to get both seats to sound good. I know that I'm going to have a one seat wonder due to the locations I've choosen. But I'm hoping that the advantages will outway all other problems.
