The Matadors are made of Ash, which is light on the density like Mahogany. Gives a real mellow full tone like Mahogany, and they're Rumba shaped, which means they're wider in the middle than Gon Bops and other classicly shaped barrel congas.
So, they're going to give a super mellow full round sound.
I heard from a few Congueros around here that the Matadors are actually made from the same shell that they make for the top of the line Giovannis,, but they have slight imperfections, so they become the "second in line". Of course, that's probably an urban myth.
Well, I just had to modify what I said earlier!
Just looked up LP's congaline:

So, if you pick up the drums and they weigh a ton, then they're Oak - and the sound will be loud and sharp. If they're fairly light, then they're Ash, and they'll be much mellower.
