I have a pair of LSi15's on the way. I am reading on this forum that they are power hungry. My amp(HALO A52) generates 225 watts into 4ohms. I know that is within the printed polk Specs for this speaker, but, I want the opinion of a private owner. Also, what watts they use to feed the LSi15's. I will trust my ears when I listen to them, just want to hear from you all.
