Anyone know of an ultracompact mono audio amp capable of around 10W? Fidelity and high end bandwidth are not that important. Response to around 1Khz would be fine. Power consumption would ideally be relatively low, so Class D/Class T is ideal if total board size can be minimized (though I don't believe there is a mono Tripath chip)
You don't say what your supply voltages are, or how small "ultracompact" is exactly, but I've used the BA5406 before for low-power audio amplification:
It's 2 low power single-supply class AB audio amps in a single package, and you can bridge them for about 10 watts into 4 ohms.
For class D, TI makes a bunch of chips like this one:
TCA0372 perhaps?
