At first I thought they were tinny, but they just needed a few days to break in. Now they sound fantastic. A lot of bass for being in-wall. However, I now have a cross-over at 80Hz and let the sub take care of the low end. They were easy to install and look great. Update: 9April2019 These continue to get better as we use them more.
