My understanding is that you actually only need .1 watt RMS for a

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.
Thanks. Wow!
