Off Axis Tweeters
If I am positioning my tweeters off axis, on the sail panels pointing straight across the dash at each other, is it important to make sure they face each other *exactly*? As in take a laser pointer and center themselves on each other?
Just curious about cancellation and the sort. Thanks.

As with any speaker listen to them in various spots. I've found speakers tend to sound best on axis. You get the most information that way. When I'm buiding a one seat car I usually start by point the tweeters right at me. Each tweeters off axis response will be different though. In general smaller dome tweeters have better off axis response so depending on what you use, it can greatly effect your results.

I am also a big on axis fan, whenever possible that is how I will mount them.
My current vehicle has the tweeters off axis, this worked best in the scheme of things. I still want all of the information possible so I tested where they sounded best! After testing numerous angles and locations the final position of the tweeters was not symmetrical to each other, nor to the drivers position or passengers position. So my answer is "step away from the laser pointer" and put speakers where they sound best to you in your car.

Thank you very much guys. I did in fact put them all over the place, even on axis with tape before settling on the sail panels. They sounded very bright on axis, and since they are considerably higher, ( bottom doors to sail panels ) on axis sounded seperated. This way they have more depth, although for sure information is lost. I had the 0/-3/-6 db option but left them at zero.
My deck EQ only is 2 band parametric and I definetly have non flat frequency response :-S I guess next year I will switch for an HU with 10-15 band EQ like the 880prs or the x993 etc.
