Sealed Back Line Array Drivers

Wiseguy, I get the impression that you come from a pro-sound background.  Is this true?  You seem to be looking for high efficiency and high power handling.  Just keep in mind that car audio is a completely different field.  Instead of a wide open area, you are in a confined and limited space.  What works well in one instance won't work in another.  Oddly enough line arrays are a perfect example of this as they have serious lobing issues in the near field.  Their near field is pretty large, and therefore doesn't work well in car audio or most home audio (in my experiences).  However as was mentioned above, they work great in pro sound where you want to fill as much space with sound.

Adire Audio

I guess you could say that... I personally have only be interested in the audio world for about three years. But my dad was an engineer for Universal Recording Studios before they closed their doors many years ago and Shure before they started a big layoff.

I am using two pro audio drivers up front and they are killer. I just wanted to find a speaker that would not be damaged from subwoofer excursion in the rear. I saw that these were sealed so they were appealing. I didnt want to have to build encloures for my rear 6 1/2 Koves if I didn't have to, i tried using baffles and they were usesless. Unless you guys can recommend something else...

Those Fostex drivers look interesting... Any recommendations on those? Price range?

These look sick!! http://www.fostexinternational.com/docs/speaker_comp/FE-E-Sigma-Series.shtml

Here is the diagram for the recommended enclosure for one of those full-range speakers you mentioned, Wiseguy.  I believe this setup is quite different than what you imagine it to be.  I'm not convinced that a full-range speaker application is what you really want in the back shelf.  It sounds like your main concern is that the back of the rear shelf speakers will be bombarded with sound pressure from the subwoofer and will either be destroyed or the voicing will be obstructed.  A simple side-to-side fiberboard baffle is all you really need, such as those that are part of most sedans separating the rear shelf from the trunk.  You can easily construct one using a stiff fiberboard covered with lightweight carpet and solve the problem of the impeding sound waves.  The large baffle will act as a large enclosure and let any speaker perform as it should.  Then your choice of rear speakers can be made because you want a certain overall sound in the car as the decision should be made.
