Summary:
I got quite a surprise with the Niles 650's! I thought I was compromising by getting in-walls (you know how that goes) but these are actually really good! It wasn't too much trouble to put them in the wall (wish I had run the speaker wires first though...). Overall, really good for the money. They image extremely well for being up out of the way and the bass wasn't what I would have had with a box speaker I'm sure, but it certainly was there. Gobs of detail too!

Strengths:
Excellent imaging even when placement was not ideal
