Low Qts. driver ( under .5 ) usually indicates a stiff cone suspension
High Qts. driver ( above .5 ) usually indicates a loser cone suspension
A stiff cone suspension while perfect for a box speaker will not sound good in open air it's too rigid to move enough air. I think your mid drivers have low Qts. and are meant for enclosures. It's possible the woofers could be used if their Qts. is above .5. I'm playing with some 16 inch woofers from an old Sansui XP because they have F.range printed on the magnet and their suspensions seem flexible. Your tweeters may work but they need to be 8 ohms and have a sens. rating in the high 90's.
