Sure, but by how much, and not the least: why?
It could only be the direct sound, as the diffuse in-room response would be the same., once equalised.
Does a dB here or there actually matter? The difference may be accessible to a well trained critical listener and evaluator of stereo equipment.

It is great to know a maker do design, build and sale a loudspeaker as great as this.
Now, please make yourself comfortable and think of the many composers that went to bed asking if that chord there should be D2-D3 or D3-D4, that is an octave apart in range, becomingly unable to fall asleep.
Now you are the listener...You are not going to say D3-D4 would have been much better than the heard D2-D3 the composer finally opted on, are you ? I mean, may be you are a musician and have a saying, but most people aren't.
Same goes for the rest of the cleff.
