Yes, less bass energy into the room is exactly the point. WIth a flat bass response, you're typically going to get nasty room mode peaks that result in muddy-sounding bass. If you want more bass and aren't using room correction for some reason, the solution is easy: use a tone control (or EQ) to increase the bass level to your satisfaction.
Why would putting the speaker sideways result in "bass artifacts"?
It's a pitty I cannot find the thread. There was a discussion between amir and erin on the NFS and amir recognizes some artefacts in the measurements from erin and suspected he measured the speaker sideways...and he was correct. Don't know why I cannot find it.
Hm. I'd be interested to see what that was about, I'll see if I can find it.

I agree. In the end you have a room of fixed size with some damping and want to reach enough SPL and flat FR at listening place. If this can be reached with smaller cabinet and smaller drivers, maybe this approach is superior to a big tower like F228.
I wish people would stop using the word "pressure". There is no appreciable pressure change caused by a transducer. It produces waves through a medium (air) that are felt and heard, that is all. Your wife is feeling the low frequencies, she's not complaining about the temperature increasing...
It is called sound pressure level though.
Yes, and the sound is in fact deviations in the local static pressure so the term is accurate.
We both know people use the term to describe low bass, and subsonic frequencies; just like he did.
If it didn't change, we would not hear anything. There is the background mean pressure, which stays relatively constant (e.g., subject to weather), and pressure fluctuations caused by sound waves. After all, isn't our ear a very sensitive frequency-dependent pressure transducer? That pressure concept seems to work well for B&K, Shure, and other brands of microphones. In any case, I expect that Morse & Ingard got their acoustics theory correct.
You are wrong. It always helps to thing about a speaker having a frequency response down to 0Hz. A hypothetical 0Hz tone would increase your air pressure from 1013hPa upwards, depending on the volume. At 0Hz, you also do not suffer from any room modes etc. You would also observe an increase in room temperature due to higher density of molecules per volume.
I do so as there is physically no difference of sound pressure at low or high frequencies.
Well it doesn't change averaged over time, but it does change averaged oven the room volume when the frequency is below the room modes
