The selection of in-walls is so broad, you have to spend time listening and evaluating. Ensure you understand the room and placement of the speakers for for casual or critical listening.
SpeakerCraft CRS8 In-Ceiling (Home Theater Rear)
Comments: Like the pivot tweeter...I don't have the speakers right on top of me so the sound is more natural for background details like doors being opened and footsteps. With the pivot tweeter you don't have to be picky with speaker placement.
Monitor Audio W265 In-Wall (Kitchen)
Comments: Big speaker with pretty good soundstage and bass. Kitchen can get crowded during parties so the sound gets filtered a bit.
NOTE: Good cable is required for In-wall or In-ceiling because the runs will be pretty long.
