I have no solution that I can think of to add just a subwoofer as none of the current speakers have a sub input and I'm trying to keep the AirPlay working. I have three other AirPlay speakers in other rooms.

Again, I think you would be pleasantly suprized about what you would hear coming out of a pair of Phantoms, there would honestly be no need for a subwoofer or the A9.
