How small? The Sonance is likely to be a GREAT speaker but it's a 6 1/2" requiring an 8 1/4" hole. A back box is available for it.
I say likely because the one I've installed hasn't been turned on yet. The wall box is in the ceiling of the shower stall and the wires are run, but the room isn't finished.
A good answer is easier with a clear question giving the make and model of everything. "The biggest problem in communication is the illusion that it has taken place." -- G. “Bernie” Shaw
