Here is an analysis performed by measuring dual mono 0dBFS sine waves (20Hz, 1kHz, and 2kHz) from my listening position.
My ceiling is slanted from 8 to 12 feet. The measurements are taken at my 11 foot seating position in a 30 foot room.
A volt meter was used to set the level at the speaker (while playing) to 2.83 volts.
Since the Salon2s are basically 4 ohms speakers, this computes to 2 watts (from the AHB2s.
The AHB2s produce roughly 180 WPC into 4 ohms, so these amps can produce about 106 dB (using two speakers).

The
Peak SPL Calculator can reflect a similar result when selecting in corner placement, though the Salon2s are not jammed into the corner.

The problem with some with this type of analysis is that with a couple of incorrect assumptions, it is possible to overestimate power requirements by 2X, 4X, even 8X.
The computed levels have been corroborated using the AHB2 clip indicators.
I also bi-amp that is yielding 1 to 2 dB of headroom, observationally using the clipping meters.
I am not sure why, but since I now use a DAC3/LA4 for 2-channel, the system seems louder.
It is certainly far louder than I like for music and movies. Of course with movies, there are a lot of channels firing, including 2 Rytmik E22 subwoofers.
