IMO, 3-ways are not all they are hyped to be - the crappy mid's usually do more damage than good. Maybe that's why high end component speakers are usually mid base and tweets only.
And there is no reason you can't use 3-ways with the factory set up if that's the route you want to go.

 

Personally, I like Blaupunkt. They make extremely high quality products. Drop my a PM if you have any questions on them.
