The 335PX and 336PX used the same tweeter, as far as I know there's really only the one version of the PX tweeter. I have these out of the billet housings so I could angle them more on-axis and still clear the door panel opening.Apparently I missed half of your entry...
Which PX tweeter are you using? Have any experience with the 6.5 and PX in a 2 way configuration? How much more does the 4" contribute?
What he said....If I was going to put any of them in an enclosure it'd be the mid range since it would need the smallest one. You want the MB to have as much air space as possible.
