does the box shape have anything to do with the sound ,i am designing a speaker enclosure 84" tall x 8" to 10" wide x ? deep ,but i'd like to contour the face of the box ,and try to aim each drive to the sweet spot.any thoughts?

Ther actually have been commercial designs that had a spiral shape, with mediocre result. Line arrays don't require special aiming techniques in home usage. In large concert venues 'J' arrays are used to control vertical directivity but even then the individual elements are still aimed on the same horizontal axis.

ok thank you ,i'll get a handle on this yet,lol
does the size or the driver have any thing to do with the sound or output ,other then lows.i know a single 3.5" driver is not going to put out as much sound or spl as a 5.25" or 6.5" even , but i would be moving the same cone space on my speakers ,weather its the 3.5" or 5.25" ,just more or less drivers to make up the 84".
so back to my question if size matters?

There are a minimum of 3 T/S parameters used to derive the anticipated response of a driver, and those are Qts, Vas and Fs. Driver size is not there. Additional parameters can be used to further quantify a driver's probable performance, but the actual driver size is way down on the list. An in depth discussion of how all the parameters affect performance is well beyond the capabilities of a web forum, as that information literally can fill a book- which explains why there are dozens of books written about the subject. If you plan on getting serious at all about this stuff you're going to need at least two on your shelf.

The two most often quoted items regarding driver performance are size and wattage; they are probably the two least significant indicators of potential driver performance.
