    All Pass Filter is a form of time delay. So what I'm thinking is if the timing is just right, then the phasing would be a non-issue. Also, it appears that these circuits are specifically built for the drivers in use, as well as the vehicle its placed in. Am I correct?

    Of course an allpass filter is built specifically for the application. A speaker just models up as a sum of electronic parts which interacts with a circuit just the same as the rest of the components.

    as for tuning ot the environment, well that's why we use multi-functional processors to start with, yes?

    Thats what i was thinking. So there really isnt an advantage for this over a standard processor. I would assume better off for home use.

    The advantage if you are a DIY kinda guy is to be able to add features to a processor you already have. So that if you have already picked a candidate processor, such as an alpine model because it integrates into a cd player you already have, or a bit1 because you want a unique feature of that processor, but gosh darnit you really would like to adjust phase on a couple of the channels, you can have your cake and eat it too without buying multiple processors.
