Dsiggia,
You are absolutely fine with either speaker as long the impedence doesn't swing or dip wildly as Mahandave mentioned. Obviously, the higher the sensitivity the better for dynamics and extra headroom with an amp, but I have two sets of 97dB speakers(one using almost the same Emminece 12" woofer as the Tylers) and have driven them with amps from 6 watts per channel up to 50 watts. The 6 wpc Art Audio PX-25 SET does a kickass job of driving my Cain & Cain I-Bens without ever seeming to run out gas.
I tend to believe(and many others) that an amp's power supply is a bigger factor than the output tube's max power potential. If the PS sags under load then it doesn't matter if the tube is capable of 50+ watts.
