If not in ceiling speakers, then perhaps some of those outdoor Mirage speakers. They look less like a speaker than the standard Omnis mentioned by CraigV, but will throw a large stage. Sort of the same issue though, not a ton of bass, but you will likely have a similar issue with in ceiling.
I personally just put the music on in the living room, because there is no escaping the sound in my house. Everywhere you go, even in the back yard, you can hear it.
