yes you are right
locations of the speakers is one of the most important factors to achieve high SQ
you don't want your tweeters to be behind your ears....
have you ever been to a concert where the singer sings behind you?
you ALWAYS want the music to be coming from the front...
or your ears will get tired real soon...
does the 10.2 t come with a crossover?
try to cross the tweeter at a high frequency or if you can...
run them at -3db/-6db
this way your mid should sound a bit louder
so it seems like the crossover settings could be a solution for you...
don't under estimate them
the quality and settings of the crossover makes huge differences.
