Question about Meadowlark E Floorstanders

I have a pair of Kestrel 2s that sound great powered by a Rogue Cronus integrated tube amp. The Cronus is rated at 55WPC into 8 Ohms. I also found that the 8 Ohm taps sounded better than the 4 Ohm ones, so in my experience they are very easy to drive. I do not biwire but use the jumpers that came with the Kestrels. Also I have no problem powering them to quite loud levels with this amp in a moderately sized room 15L X 12W X 8H.

Yeah my room is about the same (12L x 14W x 12H), I use the speakers for music and HT. And most amps I see are about 100watts into 8ohms and anywher from 150 to 200 watts into 4ohms. My concern is that i would damage the speakers, is that possible?

Provided you are using quality amplification that won't clip into the load afforded by the Meadowlark at the power levels you need in your room, it is better to have a more powerful amp than an under-rated one. It is usually amp clipping that causes the damage to the speakers when pushed. Personally, I can't imagine listening at levels that would damage my speakers, let alone my ears. Generally, 1 or 2 watts will be nominally loud enough, the extra watts are for the transients. How loud do you need to go? And how far away from the speakers will you be seated?
