Question on speaker sensitivity / power.

I was looking at some Opera Callis bookshelf speakers and noticed that they are rated for 50 watts max and have a sensitivity of 86db. I would think speakers with that low of a sensitivity would actually perform best with a more powerful amp. Am I off base on the power/sensitivity issue?

1 watt = 86db
2 watts = 89db
4 watts = 92db
8 watts = 95db
16 watts = 98db and so on.
You have to double wattage to gain 3db.
You have to go up about 10db to hear a doubling of volume.
THX is 110db, Ultra THX is 112db.

Yes, I'd suggest at least 100 watts on those speakers. 200 won't hurt?
