I had a wired system many years ago with nice $1000 in ceiling speakers. Not surprisingly that is an awful place to put speakers unless you live horizontally a lot. I never put in a wired whole house audio again and used Sonos for a while. Sonis which was a pretty big upgrade in terms of functionality and sound. But today there are tons of active speakers to choose from $30 to thousands. That’s what I do now where I want sound. I also learned I need good sound in many fewer rooms that is typical for whole house audio. A simple and cheap Bluetooth speaker fits many uses.
Be sure you like whatever interface your stuff uses. For just whole house audio type stuff that is IMO more important than the speaker fidelity.
