My understanding is that you actually only need
.1 watt RMS for a
sound to be audible ... but could be wrong on that.
Much less. If you have a 100% efficient speaker radiating equally in
all directions then 1 watt will produce an SPL of 109 dB at 1 meter
distance.
Most speakers have very low efficiency. Assume 1%, that still means
89 dB at 1 meter.
