First impressions

[Jean-Marie]

Now that we're talking about  electricity bills, how is it looking for all you early adopters? Seriously, though.
I'd like to know what I'm getting into cared:  

A good point. Is the extremely low efficiency of the speakers really reflected in power consumption at lower SPL levels? In fact, what is the max power consumption? I know the power of the amps, but not their efficiency.

This is completely different because of SAM.

if you look at 3kW to reach 105 dBA SPL it means an efficiency of 70 dB for the speakers. However, this is only true at the lower end of the spectrum. given the size of woofers and that there are two of them, I would think that at soon as you are in 100 Hz or more you are more into an efficiency in the 95 dB (I'm using a typical response curve for woofers of similar size). Contrary to passive speakers design where you need to align the efficiency of the speaker to its lower point and therefore is dissipated as heat by the filters, SAM and active amplification adapts and therefore the phantom is low efficiency only on the lowest part of the spectrum.

Add to this that the ADH amplification is very efficient (very close to class D from an efficiency perspective since the class A part is only a 6W amp) I really doubt that when playing music you would see any significant difference between a pair of phantoms and a expert system paired with 90+ dB. If what you are listening to is pure tones at 16 or 25 Hz, though you would see a difference, but musical programs are rarely that way.
