Have anyone heard of the NXG pro series inwall speakers and if so are they any good I found some on the hififorless website for what seems to be a good deal. Also I will be using a fixed freamed screen for my projector and was wandering if three center channels in front or two regular 6 1/2 inwalls with one center would sound the best. Please help before I make a mistake with the wrong speakers and and wrong setup.
