The use of in wall or ceiling is dictated by the application and what will fit. And, I'm stating that IMO it's not worth spending "a lot" of money on in-wall/ceiling speakers because I think that the envirnoment and mounting location compared to listening position(s) precludes good (audiophile) quality sound not to mention the inherent limitation in speakers such as these. Also, the usage (background/party/entertaining) isn't conducive for serious listening anyhow - at least that's how I use whole house audio. So, I didn't buy the cheapest stuff out there but I didn't spend a fortune either.
