I used the Mini Grands for my main system for 7 years. I loved them for there uncanny midrange and lifelike imaging, and hope you get a chance to hear them set up near optimal. There should be an external DAX crossover that matches output between subs and ribbons for amps differing in sensitivity (or for personal taste). The crossover also cuts the signal to the ribbons below 80 Hz (If memory serves me correct). You will need two amps to drive the system.
As far as dialing them in quickly, that will be difficult. Allow 48 minimum from back walls, and experiment with toe-in, but not more than an inch or so. Even if your listening seat is only 8 from the speaker, allow at least that much space between the speakers. Listening height is critical for proper balance, but the rake of the speaker can be adjusted to compensate (Apogee included a plumb-bob to help get both speakers matched). Very minor adjustments can yield incredible results, and can be dialed in more quickly as you become accustomed to their capabilities. For maximum impact, work at positioning the panels for midrange magic, and realize that, with time, the rest of the system can achieve equal articulation and transparency.
Keep speaker cable runs short to the ribbons, (I butted mono blocks up to the rear of the panels) they need lots of current, so opt for a smaller gauge (fatter wire)
technology be damned.
Hope this helps
